3. My work as a historian is interdisciplinary, striving to understand and present historical

events and movements in a broader context that often includes demographics, economics

and, increasingly, theories of human behavior. One of my areas of interest and expertise is

the emergence of monogamy in western societies.

4. In June of2010 I was contacted by Craig Jones of the British Columbia Attorney General.

Mr. Jones described the Reference case to me and asked if I would be interested in

assisting the Court by preparing an expert report and, if necessary, by testifying. I agreed to

do so.

5. Mr. Jones emphasized to me, and I understand, that my duty in preparing the report and, if

called upon, in testifying, is to assist the Court and not be an advocate for any party. Mr.

Jones emphasized that I should follow the evidence where it leads and draw what

conclusions I consider merited.

6. I have prepared a Report which is attached as Exhibit "B" to this Affidavit. It is based on

previous work and writing I have done on the topic, and a renewed review of the available

evidence in the academic literature. I am solely responsible for its content.

7. My report focuses on three issues: (l) the origins and development of the institution of

socially imposed universal monogamy and its displacement of polygamy in world history

(polygamy here I use to mean polygyny - polyandry, while documented, is so rare as to be

irrelevant to the issues I examine); (2) the consequences of socially imposed universal

monogamy, and the reasons for its success; and (3) the extent to which socially imposed

universal monogamy, in the western tradition, can be said to be based on religious doctrine.

8. My opinion on each of these questions may be summarized as follows:

9. The origins and development of the institution of socially imposed universal monogamy:

Monogamous marriage practices have historically occurred in the form of Ecologically

3

Imposed Monogamy (ElM), where polygamy is socially condoned but effectively

restricted by male resources and often only a small minority of all unions are actually

polygamous, and in the form of Socially Imposed Monogamy (SIM), where polygamy is

banned regardless of male status and resources. Socially Imposed Universal Monogamy

(SlUM) refers to the prohibition of polygamy for all members of a given society. Most

societies in world history condoned polygamous practices. SlUM is first solidly

documented for ancient Greece and Rome in the first millennium BCE, was subsequently

endorsed by early Christianity, and remained dominant in post-ancient Christian Europe.

With modern European imperialism and colonization, SlUM became a globally dominant

norm in most parts of the world except the Islamic Middle East and sub-Saharan Africa.

10. The consequences of socially imposed universal monogamy, and the reasons for its

success: Modem theories of polygamy emphasize the inequalities that this institution

entails and reinforces. These inequalities are manifold: they occur among men, among

women, and between men and women. The imposition of SlUM, by contrast, reduces

inequality among men and between men and women, with mixed effects on inequality

among women.

11. It is plausible, but likely unprovable, that SlUM has been a contributing factor for the

relative pace of western development. Empirical tests of the correlation between polygamy

and various indicators of development have produced conflicting results concerning the

relationship between polygamy and political development but generally tend to reveal a

negative relationship between polygamy and socio-economic development, or, to put it

another way, a positive correlation of SlUM with such development.

12. The extent to which socially imposed universal monogamy, in the western tradition, can be

said to be based on religious doctrine: Ancient SlUM emerged as a secular practice within

the context of city-state republics in ancient Greece and Roman and seems connected to

egalitarian norms. Ancient Jewish culture and religion accepted polygamous practices. By

contrast, the New Testament record favors monogamy and at least implicitly rejects

polygamous practices. These preferences are couched in religious terms. Early Christian

4

authorities commonly condemn polygamy or at least do not consider it acceptable behavior

for their own times. Ancient Christianity largely developed within the context of normative

Greco-Roman SIUM; Christian and secular monogamous principles were therefore tightly

enmeshed and SlUM, whilst championed by Christian authorities, was also viewed as a

Roman custom. After the failure of the Roman Empire, the ascent of Islamic polygamy and

of other non-monogamous groups served to associate SlUM more specifically with

Christian doctrine. The medieval Christian churches were instrumental in re-consolidating

SlUM in Europe and in its subsequent implementation in the New Warld and other

European colonies.

A INTRODUCTION

1 Objectives and Contents

This report focuses on three issues: the origins and development of the institution of socially imposed universal monogamy and its displacement of polygynous polygamy in world history; the reasons for the success of socially imposed tmiversal monogamy and its consequences; and the extent to which socially imposed universal monogamy, in the western tradition, can be said to be based on religious doctrine.

I address these issues by in four steps. Section 2 of Part A establishes the appropriate terminology. Part B provides a global historical outline of the development of polygamous and monogamous practices (Sections 3 and 4). Part C is devoted to theories

Scheidel p. I

of causation and empirical tests of their propositions (Sections 5 and 6). Part D deals more specifically with the circumstances of the emergence and the character of the western tradition of monogamy and its relationship to religious beliefs (Sections 7 and 8).

2 Terminology

2.1 Polygamy and Monogamy

It is important to clarify the terms used in this report. We must distinguish between "genetic monogamy," which refers to mutually exclusive reproductive mating arrangements between two partners, and "social monogamy," in which mutually exclusive pair-bonding need not be matched by reproductive outcomes. In this report, the term "monogamy" is applied to a social relationship, that is, marriage or quasi-marital cohabitation, without regard to actual practices of sexual intercourse.

"Polygamy" may involve one male and multiple female partners ("polygyny") or one female and multiple male partners ("polyandry"). Although polyandry has occasionally been documented, it is rare in the historical and anthropological record and will not be considered here (e.g., Levine 1988; Durham 1991: 42-102).

There is no clear semantic divide between polygynous "polygamy" that entails marital or quasi-marital relationships and forms of "polygyny" that involve more casual relationships between a married man and women other than his lawful wife. For the purpose of this report, I apply the term "polygamy" (defined here solely as polygynous polygamy, as explained above) only to official marital relationships between one husband and multiple wives and to analogous relationships that closely mimic marital unions, such as cohabitation with concubines. This usage accounts for the fact that it is difficult to separate unions with multiple wives of equal status from those with one principal wife plus additional wives of lesser status or those with one wife and co-resident concubines. I apply the term "casual polygyny" to relationships that do not constitute or closely mimic marital relationships, such as informal sexual relationships between a man and female subordinates (servants etc) that were not socially recognized as stable commitments.

2.2 Ecologically and Socially Imposed Monogamy

The academic literature recognizes a distinction between "Ecologically Imposed Monogamy" (ElM) and "Socially Imposed Monogamy" (SIM) (Alexander et al. 1979: 418-20). ElM occurs in an environment in which polygamy is admissible in principle but effectively constrained by ecological factors that limit the resources which enable men to gain access to and support or control multiple wives. In this context, only resource-rich men will be able to engage in polygamous practices. It is possible for a society in which only a very small proportion of all men practice polygamy to be classified as "polygamous" as long as access to resources is the only effective constraint on polygamous practice.

By contrast, SIM entails the normative prohibition of polygamous relationships regardless of resources. In this context, even resource-rich or otherwise powerful and high-status men are prevented from engaging in polygamous practices. In my own work,

Scheidel p. 2

I have proposed the term "Socially Imposed Universal Monogamy" (SlUM) in order to clarify the nature of this condition (Scheidel 2009a: 282). It serves to emphasize that no­one, not even state rulers, are formally exempt from this rule. l This is the prescriptive norm that generally prevails in modem western societies.

2.3 Configurations of Polygamous and Monogamous Practice

It is important to realize that these superficially neat concepts fail to capture the complexity of real-world differentiation among marriage and mating practices, especially in the global historical long term. In earlier work I have proposed a schematic trichotomy consisting of three distinct configurations (Scheidel 2009: 282). They are ideal types that facilitate categorization of practices encountered in a wide variety of environments.

The three types are: (1) ElM, where polygamy is considered legitimate and practiced according to

men's means. This situation was common in the majority of historical societies (see Section 3).

(2) SIM or SlUM that co-exists with habitual "casual polygyny" (as described in Section 2.1). In these cases husbands are prescriptively limited to marital relationships with a single wife but their casual sexual and potentially or effectively reproductive relationships with other women are not subject to legal sanction or their wives' consent. Such relationships include relationships with female subordinates (slaves, domestic servants) or with mistresses residing outside the marital household. This situation was common in ancient and medieval societies that imposed SlUM (see Section 3).

(3) SlUM that co-exists with a high incidence of effective monogyny, where exclusive relationships between one husband and one wife are a societal ideal and extra­marital relationships do not normally go beyond casual affairs or encounters with prostitutes. This situation is common in contemporary western societies.

The heuristic distinction between Types (2) and (3), whilst by no means clear-cut, is important for understanding the difference between pre-modern and contemporary forms of SlUM (see Section 7).

B. HISTORICAL OUTLINE

3 Global Developmental Patterns of Polygamy and Monogamy

3.1 Evolutionary Background

Physiological evidence suggests that humans are predominantly monogamous and only mildly polygamous in both "genetic" and "social" terms. A moderate degree of polygamy may be extrapolated from two observations. One is that in humans, adult males are on average bigger (i.e., taller as well as heavier) than females. Male-biased sexual dimorphism is a correlate of polygyny: the more polygynous a species is, the bigger

I While SIM might be limited to certain elements of society, the tenn SlUM clarifies that monogamy was a prescriptive norm without exceptions.

males are in relation to females. Species with female harems consequently display extreme levels of dimorphism: male sea lions for example can be three times as heavy as females. The human dimorphism index of 1.15 (based on weight and height) indicates that humans are only mildly polygynous. This basic ratio has been traced back as far as Australopithecus afarensis more than 3 million years ago (Reno et a1. 2003). The other reason is that whereas "Mitochondrial Eve" - our matrilineal most recent common ancestor -lived about 200,000 years ago, "Y -chromosomal Adam" - our patrilineal most recent common ancestor - is considerably less distant, having lived only 90,000-60,000 years ago. This is a function of the generally well-documented fact that male reproductive success tends to be more variable than for females, which is consistent with some degree of polygyny.

3.2 Global Incidence and Distribution of Polygamy and Monogamy

This notion of moderate polygamy is supported by the global anthropological record. We observe that most documented societies condoned polygamy but also that most actual bonding and mating arrangements were monogamous. Of 1,154 societies described in the Human Relations Area Files (a large global database of anthropological information), 93% recognize some degree of socially sanctioned polygyny, and in 70% of all cases polygyny is the preferred choice (which does not mean that it is dominant in quantitative terms) (Clark 1998: 1047). The "Ethnographic Atlas Codebook" classifies 186 of 1,195 societies for which data are available as monogamous, or 15.6% (Gray 1998: 89-90).

Precision is difficult to attain due to the frequent failure to distinguish between rare, de facto absent, and formally banned social polygamy, or between polygamy as a form of formal marriage and other forms of cohabitation. This casts doubt on the finding that among 862 societies surveyed in George Peter Murdock's Ethnographic Atlas, "monogamy" is observed in 16% of all cases (n=134).2 In a more recent study of 348 better-known societies, 20% (n=71) are defined as monogamous whereas another 20% displayed limited polygamy and fully 60% more frequent polygamy (Burton et a1. 1996: 89). These numbers are problematic because the underlying coding scheme assigns each society to a single category. This raises the possibility that some or perhaps even many of these putatively "monogamous" cultures allowed for a measure of polygamy, most notably among rulers or the ruling class, or tolerated some form of concurrent concubinage.3 This problem is well illustrated by the "Western North American Indian Data Set." In each of its 172 societies, monogamy is found to be the dominant form of marriage, accounting for 60+% of all unions (Jorgensen 1980; 1999: 235-266). At the same time, in only 28 cases, or 16%, is polygamy reported to be absent or very rare: once again, the failure to distinguish between "very rare" and "no polygamy" is critical (Jorgensen 1980: S0291; BorgerhoffMulder et a1. 2006: 61).

2 Murdock 1967: 62-125. Murdock 1981 surveys the 563 best-known of 1,264 societies. In this sample, independent monogamous families account for 11.7% of the total (n=66) (133 table 4). , This suspicion is borne out by the fact that ancient Egyptians and Babylonians are classified as "monogamous," regardless of well-documented resource polygyny amongst their rulers: Murdock 1967: 82, 86. In the same vein, Manchu and northern Chinese are likewise counted as "monogamous" (86).

Scheidel p.4

The standard anthropological surveys are a blunt instrument for establishing the incidence of SIUM. It is highly likely that many of the societies that are classified as "monogamous" merely exhibited high levels of ElM, to the extent that monogamous practices were effectively pervasive, yet without being the result of prescriptive norms. For all their deficiencies, these surveys convey the impression that largely monogamous systems were not very common and that SlUM was even rarer in world history.

Monogamy and polygamy are non-randomly distributed in both spatial and developmental terms.4 One study draws on data from 351 societies to divide the world into nine macro-regions defined by systematic variation in social structure. Most of Eurasia and North Africa consist of two regions labeled "North Eurasia & Circumpolar" and "Middle Old World.,,5 These major cultural entities broadly correspond to fundamental phylogenetic divisions (Jones 2003: 506). The North Eurasian and Circumpolar region is the older of the two and associated with moderately patricentric kinship systems. The Middle Old World region was a later development probably linked to the rise of pastoralism and later farming, and defined by strong patricentrism and the political and military dominance of patrilineal groups.

Cross-culturally, matricentrism is strongly correlated with monogamy and patricentrism with polygyny (Burton et a1. 1996: 93-94, cf. 109 fig.13). Thus, the earliest evidence of SIUM - in ancient Greece and Rome (see Sections 4.2 and 7) - hails from the fault-line between these two Afroeurasian macro-regions and more generally from a more or less polygynous environment. This suggests that the emergence of SIUM in these societies represented a break from past practice and not merely an elaboration of regionally common norms.

4 Historical Development of Monogamy Relative to Polygamy

4.1 General Background

Moderate and ecologically mediated polygamy appears to have dominated for millions of years. Francois Nielsen's analysis of Murdock's data shows that a weak developmental trend away from polygamy was reversed in advanced horticultural societies (where women's labor was and still is generally critical in generating resources) but subsequently resumed in agrarian systems: "monogamy" is attested for 10.5% of the surveyed hunter-gatherer cultures (n= 172), 24.8% of simple horticultural systems (n=157), 6.5% of advanced horticultural systems (n=261), and 41.5% of agrarian societies (n=135), as well as for 12.1 % of fishing cultures (n=58) and 21.6% of herders (n=74).6 This is consistent with the observation that in the Standard Cross-Cultural Sample (n=186), "46% of larger states have socially imposed monogamy, compared to 26% of smaller states, 10% of chiefdoms, and 11 % of bands and tribes" (Sanderson 200 I, 332). It must be noted the same qualifications apply as before: many of the putatively

The overall incidence is 17.9% (n=857).

monogamous socIetIes may merely have been characterized by high levels of ElM instead of being governed by formal monogamous norms.

While agrarianism curtailed polygamy, in many cases it also helped to intensify reproductive inequality within polygynous systems.7 Laura Betzig has documented a close relationship between stratification, despotism, and polygamy in early agrarian states.s The pertinent evidence is massive: it extends across thousands of years of Eurasian, African, and American history. Imperial state formation was particularly conducive to the growth of harems for rulers and often the ruling elites more generally, for example in Pharaonic Egypt, the pre-Islamic and Islamic Middle East, India, China, South-East Asia, among the Aztecs and Inka, and in many African polities up to the fairly recent past (Scheidel 2009b, expanding on Betzig's work). Polygamy was normally much more limited in sub-elite circles, reflected in references to bigamy in various Mesopotamian cultures and ambiguous evidence for Pharaonic Egypt but better documentation from Zoroastrian Iran, to name just a few examples. At the same time, formal barriers to non-marital polygynous relations between men and their female slaves were normally lacking.

4.2 Greek and Roman Monogamy

The societies of ancient Greece and Rome provide the earliest unequivocal evidence of SIUM.9 Ancient Greece experienced sharp political and social discontinuities during a period of state collapse around 1200 BCE. Marital practices during the period prior to this collapse are unknown. A system of small autonomous city-states slowly emerged from the ensuing "Dark Age" (from 1000 BeE onward). The earliest texts from the post-collapse period are the Homeric epics (Iliad and Odyssey), given their final form around 700 BCE but referring back to a semi-mythical earlier period. These epics repeatedly refer to polygamous practices among the Greek leadership of this earlier, "heroic" age. to It is unknown whether or to what extent these descriptions correspond to historical realities. Even so, these texts reveal a Greek perception that SlUM had not always been part of their own culture.

Historical evidence that refers to contemporary conditions in the Greek world survives from the seventh century BCE onward and conveys the impression that SIUM was by then firmly established as a prescriptive norm and considered the only legitimate marriage system. Polygamy was regarded as a "barbarian" custom or a mark of tyranny. Thus, with reference to the foreign Thracians, the Athenian playwright Euripides declared in the 420s BCE that "we count it shame that over two wives one man holds

7 Nielsen's claim (2004: 309-310) that maximum harem size was smaller in agrarian than in advanced horticultural polygamous societies is invalidated by the exclusion !Tom his sample of many of the most egregious instances of harem polygyny in agrarian empires (cf. the dataset in Betzig 1986: 107-133). 8 Betzig 1986 and numerous subsequent studies, especially Betzig 1992a, 1992b, 1993, 1995,2005. 9 Erdmann 1934: 87-103 is the most substantial discussion of Greek monogamy and polygynous practices. For Rome, see especially Friedl 1996: 25-39, 214-228, 380-394. The most important studies by non­historians are MacDonald 1990: 204-227; Betzig 1992a, b. iO Gottschall 2008; Scheidel 2009b: 286-288.

wedlock's reins."ll By implication, SlUM was therefore considered a "Greek" custom and associated with notions of freedom.

SIUM co-existed with concubinage practiced by some married men: as far as we can tell, cohabitation with concubines was deemed socially unacceptable for married men. Effectively polygamous households were therefore 'beyond the pale' (Scheidel 2009b: 289-294). At the same time, married men's sexual congress with their own slave women or with prostitutes was unencumbered by social and legal sanction (see below, Section 7).

Greek SIUM appears to have been limited to Greek city-states proper: several probable instances of polygamy among the rulers of Macedonia, a nearby Greek­influenced region, and among later Macedonian rulers of colonial empires indicate that elite polygamy persisted even in cultures that were in close contact with Greek civilization (fifth to first centuries BCE; Ogden 1999). This, together with the epic tradition concerning earlier polygamous practices, underscores the unusual character of Greek SlUM.

There is no sign of early polygamous traditions in ancient Rome. Given the lack of usable evidence from the early stages of Roman state formation and of an epic tradition comparable to the Homeric texts, we cannot tell if this absence of evidence should be interpreted as evidence of absence. In the historically documented period (from about the third century BCE onward), SIUM prevailed in Roman society. The question whether concubinage was feasible concurrently with marriage has been debated in modem scholarship and the evidence is inconclusive. It was not until the sixth century CE that an imperial decree claimed that "ancient law" prohibited husbands from keeping wives and concubines at the same time. l2 We do not know how "ancient" this norm was. As in ancient Greece, sexual relations of Roman married men with their own slave women were not formally unlawful, including relationships that resulted in offspring (see below, Section 7).

The causes for the emergence of Greek and Roman monogamy are empirically unknown because they are not directly documented in ancient sources. Possible causes are discussed in Section 7. The degree to which Greek and Roman SlUM were exceptional cannot be ascertained with certainty. Numerous contemporaneous surrounding societies are known to have condoned polygamous practices: in the Greek period, the Achaemenid Persian Empire to the east of Greece, and Macedonia and Thrace north of Greece; and in the Roman period, Celts and Germans in continental Europe, the Numidians in North Africa, and the Parthians in Iran (Friedl 1996: 29). While we cannot rule out the existence of contemporaneous societies other than the Greeks and Romans that practiced SIUM, no such cases are unequivocally attested. This strongly suggests that SIUM was a rare and possibly unique Greek and Roman custom at the time.

4.3 Survival and Expansion of Greek and Roman Monogamy

With the expansion of the Roman Empire across parts of Europe, the Middle East and North Africa, SIUM came to be common practice, although polygamy survived in

Roman territories in the Middle East. This nonn was embraced by the Christian Church as it expanded across the Roman Empire from the first to fifth centuries CE (see below, Section 8). The collapse of the western half of the Roman Empire in the tifth century CE and the dramatic reduction of its remaining eastern half (also known as the Byzantine Empire) in the seventh century CE coincided with an expansion of polygamous soCieties. The Arab conquests in the Middle East, North Africa and Spain in the seventh and eighth centuries CE spread a belief system (Islam) that accepted polygamy ("Qu'ran" 4.3). Post­Roman Gennanic practices are less well documented but polygamy and parallel concubinage did occur; only one of the several Germanic Roman-style law codes outlawed polygamy (Brundage 1987: 128-133). Overall, Gennanic arrangements do not appear to have differed greatly from the polygamous dealings recorded in the early medieval Irish tradition (Bitel 2002: 180-1, 184; cf. Ross 1985).

In the centuries following the failure of the Roman Empire, the ideal of SlUM was predominantly maintained by the Christian Church. During the Middle Ages, SlUM as a nonnative concept spread as a by-product of Christianization, a development that coincided with the Christian Church's opposition to divorce and elite concubinage (see also below, Section 8).13 Ashkenazi Jewry followed this general trend, culminating in Gershom ben Judah's ban of polygamy even if it had an existing wife's consent, around 1030 in Gennany.14 Polygamous practices remained a fringe phenomenon in medieval Europe. 15 In the sixteenth century, the Protestant Refonnation prompted a short-lived revival of pro-polygamy rhetoric but this did not have lasting consequences: an abortive episode of Anabaptist polygamy in Munster in 1535/6 demonstrated above all the failure of attempts to revive polygamy. The historicity of a decree in Nurnberg in 1650 that purportedly pennitted polygamy to alleviate the scarcity of marriageable men after the Thirty Years War is in doubt. Pronatalist proposals to legalize polygamy in eighteenth­century France went nowhere (Blum 1998). The Church of Jesus Christ of Latter-Day Saints revived polygamy in the United States in the 1830s. 16

In the wake of European overseas colonization, diffusion via European emigration and imitation by non-European societies gradually elevated SlUM to a globally dominant principle. The spread of SlUM outside Europe was slow and has yet to be systematically tracked and analyzed by academic scholarship. In their overseas colonies, European powers outlawed polygamy, although non-recognition and discouragement of polygamy rarely led to actual enforcement. In sub-Saharan Africa, head taxes that penalized polygamous arrangements were often imposed by colonial governments but primarily encouraged concealment (Zeitzen 2008: 146). Christian missionaries likewise opposed polygamy. Overall, the extent to which the incidence of polygamy declined in sub­Saharan Africa is regarded as a function of the degree of penetration of indigenous societies by wage labor, urbanization, education, and Christianization. In other regions,

13 E.g., Goody 1983; Brundage 1987; MacDonald 1995: 7-18; and cf. also Herlihy 1995: 579-580. 14 "Responsa Asheri" 41.2. Friedman 1982 discusses evidence for the survival of Jewish bigamy in medieval Egypt. 15 This is strictly a statement about polygynous polygamy as a marital or quasi-marital practice: polygynous matings were common in medieval elite groups: see Betzig 1995 and below, Section 7. 16 Anabaptists: Caimcross 1974: I-53; and cf. 74-89 on the Christian monogamy-polygamy debate engendered by the Thirty Years War. Mormons: e.g., Kern 1981: 135-204; Foster 1984: 123-225; Van Wagoner 1989. The LDS church leadership renounced plural marriage in 1890 and more forcefully in 1904.

such as the Americas or Asia, polygamy was never as widespread as in sub-Saharan Africa. In many of these regions, the same forces - European colonial rule and Christian mission - were present and the same socio-economic processes occurred to varying degrees, with analogous consequences for the incidence of polygamous practices.

To give only a few examples, in Japan, legislation against polygyny commenced in 1880; polygamy was banned in Thailand in 1935, in China in 1936 and 1953, for Hindus in India in 1955, and in Nepal in 1963 (Price 1999: 14). The least secularized Islamic countries of the Middle East and more generally sub-Saharan Africa have been the main exceptions to this global trend. 17 However, despite the Qu'ran's tolerance of up to four wives, countries such as Turkey (1926) and Tunisia (1956) have formally outlawed polygamy and others have imposed judicial restrictions on this practice, such as the requirement that an existing wife or a court approve polygamous unions (Price 1999: 15). In what has been termed the "polygyny belt" from Senegal in the west to Tanzania in the east, 20-30% of married men tend to be in polygynous unions (Jacoby 1995: 939, and more generally Lesthaeghe et aI. 1989).

There is direct continuity between the Greek and Roman practice of SlUM that was common in the mature Roman Empire (third century BCE to fifth century CE), enshrined in Roman Law, and adopted by Christianity (see Section 6) and the subsequent western tradition of SlUM, in medieval and modem Europe, in European overseas colonies, and eventually in regions under European influence. Because of this it is appropriate to define the development of SlUM in post-ancient world history as the maintenance and expansion of Greek and Roman practice. No other documented cultural traditions in other parts of the world exhibit a comparable continuity of SlUM in ideal and practice.

C. CAUSES AND CONSEQUENCES OF MONOGAMY

5 Theories of Causation

The emergence and expansion of SlUM raises fundamental questions of causation and consequences. Two distinct but related issues are at stake: the causes of variation in the incidence of polygamy and monogamy, and the motivation for the imposition of SlUM regardless of status and resources. In this section I address these issues from a general theoretical perspective. In Section 7 I focus more specifically on the origins of the western tradition of SlUM.

5.1 Theories of Polygamy

Multiple theoretical explanations of polygamous institutions have been proposed in modem scholarship. 18 However, it is important to realize that polygamy is not a single institution that is susceptible to generalizing interpretations. Polygamous arrangements

17 Bailey and Kaufman 2010: 7-68 list and discuss countries where polygamy is currently legal. 18 Zeitzen 2008: 41-65,125-144 provides the most recent survey of different approaches. For the sake of limiting the length of my bibliography, I restrict myself to referring to her survey for the remainder of this section.

occurred in a wide variety of cultural and ecological contexts and played out in very different ways depending on specific configurations of circumstances. As Miriam Zeitzen notes, most modern theories focus on one of three issues: power, politics, and prestige; production and reproduction; and gender relations (Zeitzen 2008: 47).

Theories of the first category claim that polygamy serves to create political alliances or that it functions as a marker of power (including biological seniority) and/or prestige (Zeitzen 2008: 47-56). According to these theories, polygamy has a display function, advertising and reinforcing power and resource inequality among men.

Theories of the second category focus on polygamy's association to the sexual division of labor (Zeitzen 2008: 56-65). This perspective is particularly important for societies in which the supply of labor rather than the supply of land is the critical constraint on economic success. Polygamy in sub-Saharan Africa is thus commonly associated with the benefits men derive from female labor. In practice, wealth/power and polygamy are mutually interdependent: while male wealth/power facilitates polygamy, polygamy in turn augments male wealth/power though female labor inputs. By the same token, polygamy increases male reproductive success, and reproductive success may augment male wealth/power. In all these scenarios, as before, polygamy serves as a marker and enabler of inequality among men.

Theories of the third category focus on gender relationships that are inherent in polygamy (Zeitzen 2008: 125-144). Polygynous polygamy, as defined in Section 2.1, inevitably entails inequality between men and women, with one man claiming multiple female partners. Concurrently, the sequence in which women enter polygamous arrangements and their ages often create status differences that establish inequality among women in polygamous unions.

All these theories tend to focus on male motivations for entering polygamous arrangements and their consequences in terms of fostering inequality. However, it is important to account for female choice (which I use as an umbrella term covering choices by females entering unions and those made by relatives on their behalt) as well as male choice in order to understand not only the causes and consequences of polygamy but also the causes and consequences of monogamy. I address these issues in the following two sub-sections.

5.2 Female Choice

The overall incidence of polygamy (again defined as polygynous polygamy, as throughout this report) may be explained as a function offemale mate choice. Economists have long argued that in terms of material wellbeing and reproductive outcomes, polygamy is beneficial to most women if there is substantial inequality among men in terms of resources or other properties that are relevant to reproductive success. 19 Simply put, a woman may be better off sharing a resource-rich husband with other women than to monopolize access to a resource-poor husband. In this context, moreover, polygamy not only benefits multiply married women but also monogamously married women in the

19 Becker 1974 ~ Febrero and Schwartz 1995: 316-317; Grossbard 1980, esp. 324; Becker 1991, esp. 87, 89. Becker 1991: 80-107 provides the fullest formal analysis of the economics of polygynous polygamy. See also Bergstrom 1994.

r ,

same population by allowing them to avoid unions with the least desirable males.20

Conversely, this custom benefits male polygamists but harms other men to varying degrees, the more so the more unequally resources are distributed and this inequality is correlated with polygamous preferences. The more females are attracted to polygamous relations with resource-rich males, the more males will be unable to marry. Hence polygamy tends to reinforce male inequality by matching reproductive inequality with resource inequality.21

Based on these observations, Satoshi Kanazawa and Mary Still hypothesize that the degree of resource inequality among men should have a positive effect on the incidence of polygamy.22 Furthennore, women's ability to choose a marriage partner is expected to increase the incidence of polygamy if men's resource inequality is high, and vice versa. In their view, "the extent of resource inequality among men and the level of women's power have a positive interaction effect on the level of polygyny in society" (Kanazawa and Still 1999: 33). In this scenario, the spread of monogamy is a function of decreasing resource inequality among men. These assumptions are borne out by simulation models and successfully tested against indices of resource inequality and women's power in between 54 and 102 modern countries. These data show that greater resource inequality significantly increases the incidence of polygamy and also indicate positive interaction effects of inequality and women's power on polygamy.23 Economic development is found to be negatively correlated with polygamy, suggesting that male resource inequality diminished with economic development.

Whilst this argument has stood up well to preliminary criticism (Sanderson 2001; MacDonald 2001; with Kanazawa 2001 a, 2001 b), the apparent significance of "women's power" is hard to explain given that female choice cannot be limited to a prospective wife's own decision-making. If polygamous unions with resource-rich men are advantageous, a woman's kin can reasonably be expected to arrange a marriage pursuant to the same calculus of rational choice?4 This suggests that women's power per se ought to be irrelevant to observed outcomes. Moreover, a separate model by Eric Gould and associates maintains that the composition of resource inequality is as important as its overall level. Their simulation indicates that while resource inequality based on non-labor

20 For simple illustrations of the main point, see Wright 1994: 97, repeated by Kanazawa and Still 1999: 27-28. 21 This observation is distinct from the notion that polygamy favors male polygamists if women produce gains other than children, especially by contributing to subsistence. This is held to be important in horticultural systems where women do much of the farm work (e.g., Boserup 1970: 50; Goody 1976: 34, 129; cf. also Sanderson 2001: 331). However, Bretschneider 1995: 177-179 finds little support for the concept of "wealth-increasing polygyny" (cf. White 1988: 549-550). 22 Kanazawa and Still 1999: 32-35. Sellen and Hruschka 2004 observe that the principle that "marital unions are more commonly and more highly polygynous when men differentially control access to material resources, particularly where those resources are valuable, renewable, and heritable" (707) mutatis mutandis also extends to foraging populations, with control of access to hunting and fishing sites serving as the critical variable. 23 Kanazawa and Still 1999: 34-35 (simulations), 35-42 (empirical tests). By contrast, their evidence does not show a negative correlation between democracy and polygamy; cf. below. 24 Kanazawa 2001a: 338-340 defends the concept of female mate choice against the assumption that malesmade the decisions but does not consider female choice mediated by kin. Note, however, that TertiIt 2006 discusses differences between marriage decisions made by prospective wives and those made by their fathers.

income (such as control of land and physical capital) favors polygamy, the marriage market equilibrium becomes more monogamous if inequality is determined by disparities in labor income, which tends to be a function of human capital (Gould et al. 2004). More importantly, however, neither one of these models is capable of accounting for the existence of SIUM. In principle, these models would readily allow for a moderate degree of polygamy even in the most developed countries today, at the very least among the very wealthy. I conclude that female choice theory is necessary but insufficient to explain SlUM and that we need to take account of male choice to make sense of this institution.

5.3 Male Choice

A "male choice" approach to polygynous polygamy and monogamy is likewise predicated on the observation that in the context of male resource inequality, polygamy tends to favor many women and disadvantage many men. This situation, in tum, is inherently conducive to inter-male conflict and competition and thereby impedes cooperation and curtails collective action?5 The negative effects of intra-group conflict and the benefits of cooperation supply an incentive for males to engage in bargaining in order to reduce polygamy and thus overall reproductive inequality within a given group. As Richard Alexander and associates put it, "the net effect of rules prescribing monogamy is almost certainly a significant depression in the variance of male reproductive success relative to that in stratified societies which do not prescribe monogamy" (Alexander et al. 1979: 420). Since this form of compromise bargaining erodes the reproductive advantages customarily enjoyed by resource-rich elites, it is unlikely to occur in the absence of powerful incentives.

The drive for competitiveness mediated by inter-group conflict has been identified as a plausible incentive. All other things being equal, formal restrictions on polygynous polygamy (e.g., a limitation to bigamy) and even more so its complete prohibition in the context of SlUM can be expected to reduce competition within the group and increase cohesion and cooperation and hence inter-group competitiveness.26 In the most basic terms, reducing reproductive inequality is thought to promote collective action, which must be considered a vital element of successful state formation (e.g., Blanton and Fargher 2008). Simply put, this line of reasoning supposes that SIUM is conducive to collective action and therefore yields tangible societal benefits.

5.4 Summary

All the theories under review emphasize the inequalities that polygamy entails and reinforces. These inequalities occur among men (because of differential access to wives), among women (because of hierarchies among wives in plural marriages), and between men and women (because of the gender asymmetry inherent in polygynous polygamy). By contrast, the imposition of SIUM is viewed as a measure that is meant to

25 For the correlation between sexual dimorphism (a proxy of polygyny, see above) and the intensity of male-male conflict in other species, see esp. Alexander et al. 1979; Mitani et al. 1996; Weckerly 1998. 26 Alexander 1987: 71. For a formal model in which polygamy is constrained by a ruler's need to discourage rivals, see now LagerlOf 2007. This scenario could easily be expanded to cover elites more generally.

reduce inequality among men and effectively reduces inequality among men as well as between men and women. SIUM's overall effects on inequality among women are less clear: while it removes inequality arising from hierarchies among plural wives in polygamous unions, it constrains female mate choice in ways that may increase economic inequality among women.

6 Macrosocial Consequences of Monogamy

The hypothesis that SlUM is conducive to collective action is susceptible to empirical testing. For practical purposes we may distinguish between a "weak" and a "strong" version of the notion that monogamy confers societal benefits. The "weak" version holds that if monogamy can be shown to have been positively correlated with advances in social complexity - for instance, from hunting/gathering, pastoralism and horticulturalism to agrarianism, or from tribes or chiefdoms to states - it is reasonable to suppose that monogamy is also positively correlated with the increase in social cohesion and competitiveness that enabled these transitions to occur. This notion is supported by the observation that polygamy is less common in agrarian societies than in other systems (see Section 3.2). At the same time, however, imperial state formation in particular can often be shown to be associated with dramatic intensification in resource polygamy27 This makes it impossible to substantiate any claim that monogamy was a necessary precondition of social up-scaling (cf. also MacDonald 1990: 198, 204). Moreover, we cannot tell if monogamy became more common because of overall development or whether development was contingent on an expansion of monogamy. In other words, we cannot easily distinguish between cause and effect.

What one might call a "strong" version of the notion that monogamy confers societal benefits holds that polygamous societies tend to be less competitive than monogamous ones. In consequence, once SlUM had emerged, it gradually out-competed polygamous societies for human and material assets. In Richard Alexander's view, the rise of stable large states (loosely if not entirely accurately labeled "nations") was causally linked to this institution: "It is almost as if no nation can become both quite large and quite unified except under socially imposed monogamy" (Alexander et al. 1979: 432-433). Alexander also claimed that SIUM tends to coincide with "the vote, representative government, elected (not hereditarily succeeding) officials, and universal education" (Alexander 1987: 72).

Two systematic statistical tests of these assumptions were independently produced in 1999, followed by a similar one in 2005 28 These are the only such tests known to me. Drawing on samples comprised of between 54 and 102 different countries in 1960, 1965 and 1980, Kanazawa and Still find that, depending on the statistical methods employed, the level of democracy either rarely or never has a significant effect on the level of polygamy (Kanazawa and Still 1999: 38-42). By contrast, Michael Price

27 See esp. Betzig 1993a; Scheidel 2009. White and Burton 1988 maintain that the incidence of warfare for plunder and capture of women is positively correlated with the incidence of polygamy, and Bretschneider 1995 finds that in the 186 societies of the Standard Cross-Cultural Sample polygamy is a positive correlate of successful inter-group warfare_ 28 Kanazawa and Still 1999; Price 1999; Tertilt 2005.

Scheidel p.13

argues that Alexander's assumptions are consistent with both historical and contemporary evidence. He interprets the spread of SlUM from highly localized beginnings to a global phenomenon as a function of the expansion of European powers at the expense of other (non-SlUM) competitors and the eventual imitation of Western practices by other societies (Price 1999: 33-45). In addition, he investigates the relationship between SIUM and state success by comparing contemporary monogamous and polygamous societies with the help of standardized measures of cooperativeness. Using population size, use of the death penalty, democratization, corruption, and per-capita GDP as proxies, he shows that in a sample of 156 states, monogamous ones are more populous, less likely to use the death penalty, less authoritarian, less corrupt, and richer than their polygamous counterparts (Price 1999: 45-52; see also Sanderson 2001: 332). Similarly, in a more narrowly focused comparison, Michele Tertilt finds that in a sample of 28 polygamous countries, total fertility, infant and child mortality, and the age gap between spouses were higher and per capita GDP was lower than in 58 countries that are located relatively close to the equator.29 In a quantitative model, she projects that banning polygamy in sub­Saharan Africa would reduce fertility by 40%, increase savings by 70%, and increase output per capita by 170%. Her model expressly does not set out to disentangle the importance of different factors that contribute to sub-Saharan African underdevelopment but addresses the question whether enforcement of monogamy would playa positive role (Tertilt 2005: 1342). Her findings strongly suggest that monogamy would have a strong beneficial effect on the affected populations. While Tertilt does not address political issues, Price finds that in his own sample, monogamous countries were 2.6 times as likely to be "fully democratic" as polygamous ones, and that polygamous countries were 4.1 times as likely to be "authoritarian" as monogamous ones (Price 1999: 49). This difference in outcomes (between Kanazawa and Still on the one hand and Price on the other) is hard to explain and probably reflects different scoring methodologies.

But this is not the only problem. Assume for a moment, if only for the sake of argument, that Price's findings are valid. Even in that case they raise questions of cause and effect. If SIUM could be shown to be positively correlated with societal success and wellbeing, would that mean that the success of societies that are characterized by SlUM is causally related to the practice of SIUM, or rather that SIUM is a side effect of independent developments that caused these societies to be more successful?3o Price acknowledges this problem but adduces a number of arguments in support of the former position, i.e., that "monogamy has been to some degree responsible for the success of the West" (Price 1999: 56-57).

In my opinion, several of his arguments fail to support this claim. He notes that ethological and anthropological theory suggests that sexual competition of the kind that is intrinsic to polygamy (driven by reproductive inequality and scarcity of marriageable female partners for lower-status men) leads to violent conflict and that SIUM would serve to mitigate such conflicts and promote cooperation. This is simply a restatement of the "male choice" theory described above (Section 5.2) and invites qualification: historical polygamous polities (such as most premodern empires: see Betzig 1986; Scheidel 2009b) were often very successful in expanding at the expense of their

" Tertilt 2005: 1347. She chooses latitude as a criterion to increase comparability with polygamous countries, many of which are close to the equator. 30 Emphasized by Wilson 1995: 37. Cf. also Price 1999: 29-30, 55.

competitors, conceivably because polygamy mobilized and channeled male violence for the purpose of outward predation and capture of additional women. This view is consistent with the finding that according to cross-cultural surveys, the incidence of warfare for plunder aud capture of women is positively correlated with the incidence of polygamy (White aud Burton 1988; cf. also Bretschneider 1995). On balance, therefore, it seems that while SlUM might logically be expected to increase collective action, polygamy at least under certain circumstances generated similar effects. While this does by no means invalidate the notion that SlUM is likely to promote societal success, it shows that polygamy is likewise capable of promoting this goal. Price's observation that polygamous empires were eventually eclipsed by monogamous western powers is factually correct but does not establish that SlUM significantly contributed' to this development.

Price notes that "if any aspects of Christianity have been responsible for the success of Christiau societies" it would have been the ones that had tangible effects on actual behavior. Post-Roman SlUM, promoted by the Christian Church (see Sections 4.3 aud 8), would have been one of these factors. However, this notion is predicated on the claim that Christianity was indeed responsible for the relative success of (Christian) western societies, which is possible but has not been established, aud is not currently considered to be a crucial variable in academic debates concerning the question of the "rise of the West" (see below). His observation that, in Europe, SlUM greatly predated modem development speaks against considering it as a mere by-product of modernization. This, however, does not demonstrate that SlUM was more than a neutral feature aud that it ultimately contributed to modernization. He also fails to substantiate his claim that non-colonized countries eventually embraced SlUM not just "because they begau recognizing Western economic and political dominance" but more specifically "in order to remain competitive with traditionally Christian nations" (Price 1999: 44). Westernization without colonization has entailed the adoption of whole bundles of European-style institutions and we cannot tell whether by itself, SlUM has been imbued with competitiveness-enhancing properties.

Price's potentially most promising observation is that contemporary monogamous societies that cau be classified as successful (in terms of the indicators listed above) are otherwise quite diverse (encompassing European, Latin American, and South-East Asiau countries) whereas polygamous societies that are less successful are also otherwise quite diverse (encompassing Central Asiau Muslim, Arab, aud sub-Saharau African countries). This would seem to lend a measure of support to his claim that SlUM has indeed been a distinct aud causally significaut factor in societal development. However, I am not aware of scholarship that would address this issue in greater detail.

The more specific question whether SlUM signiticantly contributed to the overall success of the West is impossible to auswer for the simple reason that the causes for the "rise of the West" continue to be hotly debated in the academic literature and no consensus appears to be within reach. A wide variety of putatively significaut contributing factors have been considered in recent scholarship, including, but not limited to, state weakness and fragmented sovereignty in medieval Europe, the polycentric nature of the post-aucient Europeau state system, the demographic impact of the Black Death, institutional features such as constitutions aud property rights, late female marriage in north-western Europe, geographical proximity to the Americas and its resources, the

availability of coal in Britain, Newtonian science, the Protestant work ethic, and so on.31

While it certainly cannot be ruled out that SlUM contributed to the process of the development of powerful nation states with growing levels of social cohesion, popular political participation, ideals of equality, human rights and economic growth, the proliferation of numerous other potential contributing factors impedes empirical evaluation.

Moreover, even if marital arrangements were considered relevant to observed developmental outcomes, it would be important to note that SIUM was not the only feature in that sphere that marked out Christian Europe as unusual in world historical terms. Modern scholars have paid great attention to the practice of relatively late marriage for both sexes in north-western European countries, with both men and women commonly entering first marriages in their twenties. This custom, which can be traced back at least to the late Middle Ages, is unusual in that women generally married at younger ages in other societies. In as much as a higher marriage age for females reduced power inequalities within marriage, this custom may have had a beneficial effect on overall social development. In addition, monogamy and late marriage tended to coincide with a low incidence of marriage among close kin. Together, these three features structurally favor neolocality (the establishment of separate households for newly formed couples), which in turn is positivelr associated with mobility, independence, economic development, and spousal equality. 3

By contrast, many Middle Eastern societies have been characterized by a combination of polygamy, consanguineous marriage, and early marriage for females, a cultural 'package' that may curtail mobility and personal freedom, impede the development of strong civic institutions, raise fertility and depress per capita incomes.33

In particular, a new study finds that democracy exhibits a higher magnitude negative correlation with consanguinity than with measures of nine other factors believed to influence levels of democracy (economic freedom; education; GDP per capita; history of foreign occupation in last 100 years; human development; inequality; IQ; median age; and percentage exports in non-renewable resources), and that consanguinity is the strongest predictor of differences in levels of democracy (Woodley 2009). In other words, SlUM cannot be viewed in isolation from other structural features of the marriage system in those parts of Europe that eventually pioneered republicanism, constitutional government and industrialization. This makes the actual contribution of SIUM all the more difficult to ascertain.

I conclude that the question of whether SlUM has been instrumental in modernization and societal success, and more specifically in the creation of the modern democratic and economically highly developed state, cannot be meaningfully answered on the basis of the evidence that has been marshaled and analyzed to date.

D ORIGIN AND CHARACTER OF WESTERN MONOGAMY

7 Emergence and Correlates of Ancient Greek and Roman Monogamy

The origins of Greek and Roman SlUM are empirically unknown. There is no sign that Greek or Roman monogamy was religiously motivated or justified with reference to religious beliefs. If polygamy may indeed be understood as a female response to significant male resource inequality (see Section 5.2), it is tempting to conjecture that the collapse of the Bronze Age palace system in Greece around 1200 BCE and the ensuing reduction of social complexity in Early Iron Age Greece (formerly known as the "Dark Age") facilitated SIUM (see Section 4.2). More generally, this depression may have created the necessary preconditions for the rise of the city-state (polis) as a form of socio-political organization that was predicated upon the relative weakness of rulers and elites and correspondingly strong notions of citizenship and popular military and political participation. However, this superficially appealing conjecture may be hard to reconcile with the fact that what has been called a "middling ideology" and egalitarian institutions (culminating in direct democracy) can be observed only after the formation of post-collapse aristocracies34 For instance, Susan Lape argues that in the case of Athens, it was only constitutional and legal reforms in the early sixth century BCE that defined the monogamous conjugal family as "the sole legitimate family form" by barring legitimate or legitimizable male procreation outside marriage. Her conclusions are so germane to the issue at hand that they merit extensive quotation: "By eliminating a man's bastard children from the family, Solon's laws made is less socially useful for a man to father bastards or to keep a concubine either in addition to or in place of a wife. In this way, the family laws ... worked to inhibit a source of aristocratic power and prestige. While the family laws curbed a traditional vehicle of aristocratic self­fashioning, they also made available a new source of commonality and community for Athenian men. ,,35

Greek SIUM is therefore best understood as the outcome of a gradual process that involved the building of civic institutions and the development of ideological notions of normative egalitarianism. Comparative evidence shows that low levels of socio-economic complexity as such (as they prevailed following state collapse around 1200 BCE) are insufficient to account for the emergence of SlUM. The same is true of the format of the city-state: whereas SIUM may only have arisen in city-states (Herlihy 1995: 580), non­western city-states did not habitually adopt SlUM (Hansen 2000).

Both Greek and Roman SlUM are consistent with the "male compromise model" (see Section 5.3), the notion that universally imposed monogamy mitigates sexual competition among men and thereby also diminishes the intensity and divisiveness of other forms of inter-male competition. The Greek and Roman city-states were characterized by high levels of popular mobilization, especially in the military sphere. Many Greek city-states and the Roman state, which also began as a city-state, were republics, a political system that was very rare in pre-modem world history.

34 See, e.g., Morris and Powell 2006: 72-92, 148-170. 35 Lape 2002/2003, pp. 119-120. See also ibid. 131: "Since the men most likely to father bastard children were those who could afford to do so, namely men with enough wealth to support multiple women and children, the family legislation articulates a class bias against the wealthy and aristocratic."

Scheidel p.17

Among documented ancient societies around the globe, the specific congruence of SlUM, republicanism, citizenship rights, and high levels of collective action in the military and political spheres can only be observed in the case of Greece and Rome. The same is true of SlUM as such.36 This suggests that the association of SIUM with these other features was probably not coincidental. Given our ignorance of the origins of SIUM in these two societies, however, we are unable to determine whether SIUM contributed to these other features or whether it was a neutral element. The observation that in Greece, SlUM was gradually strengthened over time (see above) speaks in favor of a dialectical process in which monogamous norms and practices and other civic features co-evolved and mutually reinforced one another over time.

Much more is known about how Greco-Roman SlUM mediated, and was reconciled with, resource inequality. As I have argued in detail elsewhere, the institution of chattel slavery helped facilitate as well as mask effective polygyny in the context of formal SIUM (Scheidel 2009b: 284-299). Greco-Roman SIUM coincided with high levels of chattel slavery. Monogamously married men were free to engage in sexual activities with their own slaves. Thus, chattel slavery helped maintain (serial) SlUM whilst simultaneously enabling the translation of resource inequality into effective polygyny, i.e. effective sexual inequality. It is only in a closed population with a balanced sex ratio that these features could not possibly be reconciled: Greeks and Romans solved this problem by importing disfranchised women from outside their own in-groups.

This shows that the simple zero-sum model of "female choice" outlined above only applies in the absence of exogenous inputs. For SIUM to co-exist with effective resource polygyny, it was essential for slaves to be demographic outsiders (rather than marginalized group members), which was almost always the case in Greece and Rome (unlike in some polygamous societies). In keeping with "male compromise theory," this arrangement was likely to foster cohesion within the ruling group or later even within the Roman Empire as a whole (in as much as slaves hailed from beyond the imperial borders). Greco-Roman SIUM was highly consistent with the prevailing desire to reconcile economic inequality with more egalitarian ideals and the dominance of male citizens that was sustained by constraints on female mate choice (by outlawing polygamy) and the exploitation of enslaved outsiders.

This shows that Greek and Roman marital and mating practices were unusual and conventional at the same time: unusual in their observance of SIUM and conventional in their pursuit of effective resource polygyny. I emphasize this point because it set the tone for later periods. Formal SlUM continued to coincide with casual polygynous relationships with subordinates in medieval and early modern Europe (e.g., Betzig 1995, 2002). It has been argued that effective monogamy was indeed a fairly recent historical development brought about by the increasing division of labor associated with industrialization which impelled novel bargaining processes between dominants and subordinates (Betzig 1986: 103-106). This indicates that SIUM, by itself, did not fully transform effectively polygynous practice. Instead, we observe a gradual and very drawn­out trend toward greater effective monogamy.

36 Because of these multiple peculiarities, it seems impossible to use the Greek and Roman cases to develop an overarching theory for the emergence of SlUM. Instead, it seems more prudent to ascribe SlUM to "complex, historically conditioned outcomes" (thus MacDonald 1990, 1995, 200 I).

8 Religious Dimension of Western Monogamy

8.1 Jewish Tradition

Several passages in the first five books of the Old Testament. which are conventionally regarded as Mosaic Law, are commonly interpreted as evidence of polygamy ("Exodus" 21.10-11; "Leviticus" 18.18; "Deuteronomy" 21.15-17). However, whether they can be accepted as unequivocal references to polygamy is still the object of academic debate (cf. most recently Davidson 2007: 191-202). It is likewise open to discussion whether the injunction against the Jewish kings' acquisition of "many wives for themselves" ("Deuteronomy" 17.17) merely places restrictions on polygamous practice or condemns the practice as such.

Regardless of how these normative statements are interpreted, the Old Testament contains numerous unequivocal references to polygamy, most notably as being practiced by rulers and other leaders.37 It has been noted that these cases are never described in favorable terms and that many of them are presented as having been caused by problems (notably childlessness) and/or as causing problems (e.g., Brewer 2000; Davidson 2007: 181-191, 202-211). At the same time, none of these descriptions expressly condemns these cases as contravention of religious law.

The incidence of Jewish polygamy during the formative period of Christianity in the first few centuries CE remains unclear. The first-century CE Jewish historian Josephus mentions "our ancestral custom that a man may have several wives at the same time" ("Jewish Antiquities" 17.14). Actual cases of bigamy are recorded in the sources, and the Rabbinic texts repeatedly mention polygamous unions and do not normally disapprove of them as long as they were undertaken for what were considered honorable reasons (Schremer 1997/2001; Satlow 2001: 189-192). The fact that as late as in 393 CE the Roman government forbade Jews to "enter into several matrimonies at the same time" ("Justinianic Code" 1.9.7) documents the persistence of this custom into late antiquity.38 As I show in the following sub-sections, appreciation of the latently or effectively polygamous character of ancient Jewish culture is important for our understanding of the context in which Christianity developed.

8.2 New Testament Tradition

The canonical Gospel tradition (Mark, Matthew, Luke, John) does not directly comment on polygamy. The only relevant passages are Jesus's views regarding the propriety of remarriage after divorce in Mark 10.2-12 and Matthew 19.3-12. In Mark 10.11-12, Jesus is reported as having stated that

"Whoever divorces his wife and marries another, commits adultery against her; and if she divorces her husband and marries another, she commits adultery."

In Matthew 19.9, the same rule is qualified by exempting remarriage after justified divorce from this injunction:

37 Betzig 2005 provides exhaustive documentation. 38 For later periods, see above, Section 4.3.

Scheidel p.19

=

"Whoever divorces his wife, unless for indecency, and marries another, commits adultery."

The possibility that someone might take a second spouse while he or she is still married is not raised in this context or anywhere else in the canonical Gospel tradition.

lt has been argued in modem scholarship that Jesus's statements preceding these two passages imply that according to the Old Testament tradition, which Jesus endorses, marriage was a union of only two persons (one male and one female). Brewer 2000 infers this from the close linkage of two quotes from the "Book of Genesis" (1.27; 2.24) in Mark 10.6-8 and Matthew 19.4-5. These passages (both presented as Jesus's own words) read (quotes from the Old Testament in italics):

Mark 10.6-8: "But from the beginning of creation, 'He made them male and female' [= "Genesis" 1.27). 'For this reason a man shall leave his father and mother and be joined to his wife, and the two shall become one flesh. ' [= "Genesis~' 2.24]." Matthew 19.4-5: "Have you not read that he who created them from the beginning made them male and female [= "Genesis" 1.27), and said, For this reason a man shall leave his father and mother and be joined to his wife, and the two shall become one flesh' [= "Genesis" 2.24]7" In these cases, the juxtaposition of the primordial couple of Adam and Eve (one

male and one female in "Genesis" 1.27) and the reference to two spouses forming a union ("Genesis" 2.24) is interpreted as an implicit reference to the monogamous nature of such unions. The specification "the two" found in Mark and Matthew's quotes, which is absent from the Hebrew version of "Genesis," may be seen as reinforcing this interpretation, which is also lent a measure of plausibility by an analogous reference to "Genesis" 1.27 in a Jewish text from the Qumran tradition that condemns polygamy and broadly dates from the time of Jesus (the "Damascus Document" 4.21, quoted in Brewer 2000).

From the historian's perspective, it is important to stress that that proper understanding of the sayings in the Gospels - of what we might term 'original intent' -depends on their contextualization in the religious debates and social norms and expectations of the first century CE, a context which is necessarily only sparsely documented. This means that exegetical interpretation is methodologically appropriate and indeed often necessary and that the proper meaning of particular statements cannot be meaningfully established by simply translating an existing text into a modem language. As a result, the precise meaning of these two passages remains open to debate. On a narrowly literal reading, explicit imposition of monogamy or condemnation of polygamy is absent from the canonical Gospel Tradition. At the same time, the condemnation of all or most kinds of remarriage after divorce attributed to Jesus is logically incompatible with the notion that polygamy would have been considered acceptable by the same authority. On a broader, contextual reading, therefore, the Gospel tradition can be said to have rejected polygamy. Moreover, this implicit rejection is couched in religious terms because it entails reference to Old Testament texts.

In addition to the aforementioned four Gospels, the canonical New Testament also includes the "Acts of the Apostles," various letters, and the "Revelation to John." Two of the letters, 1 Timothy 3.2 and 3.12 as well as Titus 1.6, state that a man acting as a church leader (an "episkopos" in 1 Timothy 3.2 and Titus 1.6, a "diakonos" in 3.12) must be a "man of one woman." The exact meaning of this phrase is uncertain. While it is possible

Scheidel p.20

that it refers to an expectation of monogamy (i.e., the absence of polygamy), contextual information makes it more likely that it is intended to specify that such a man should not have been married more than once or that he was not a womanizer. These latter meanings are supported by the reference to a widow who was the "woman of one man" in one of the same texts, I Timothy 5.9, and by tombstone inscriptions from that period that celebrate lifetime monogamy and/or overall spousal faithfulness (Brewer 2000, with references).

I conclude that while the Gospel tradition does not explicitly and unequivocally require monogamous marriage and does not explicitly condemn polygamy, it logically and implicitly rejects polygamy on religious grounds. In addition, the roughly contemporaneous letters of Paul to Timothy and Titus, regardless of the precise meaning of the phrase "man of one woman," logically imply that polygamy would have been unacceptable behavior at least for the leaders of Christian communities. In these latter texts, this expectation is not expressly generalized to all Christians overall.

8.3 Later Christian Tradition

Any engagement with the question of early Christian posItIOns on monogamy requires consideration of the circumstances of the emergence of what is now considered the Biblical canon. What is now known as the New Testament was only gradually defined as a bounded group of texts whose composition commanded widespread consensus. The canonical nature of a 'core group' of texts including the Gospels of Mark, Matthew, Luke and John, "Acts" and a number of (mostly Pauline) letters was not established until the late second century CE (Holmes 2008: 415-420). Moreover, the extent to which Jewish scriptural tradition was to be included in the Christian canon was debated until the fourth century CEo In the second century CE, Christian writers advocated a wide variety of approaches to the Jewish tradition, such as selective acceptance of those elements of Jewish scripture that had been affirmed by the Gospels; re-definition of the Jewish scriptural tradition as prophetic rather than normative in nature; and the wholesale rejection of the relevance of Jewish scripture for the Christian community (Holmes 2008: 410-414). Under these circumstances, early Christian thinkers effectively enjoyed considerable leeway in engaging with the phenomenon of polygamy as encountered in the Old Testament tradition.

Several of the earliest surviving Christian writers disapprove of polygamy and regard it as a contravention of divine will. Justin Martyr, a Christian apologist in the mid-second century CE, states that Jews who seek to justify polygamy with reference to the biblical precedent of Jacob are ignorant and misunderstand the true nature of that case, and implies that, unlike contemporary Jewish authorities, God does not condone polygamy:

"It is better for you to follow God than your imprudent and blind masters, who even till this time permit each man to have four or five wives; and if any one see a beautiful woman and desire to have her, they quote the doings of Jacob [called] Israel, and of the other patriarchs, and maintain that it is not wrong to do such things; for they are miserably ignorant in this matter" ("Dialogue with Trypho" 134).

Irenaeus, a church leader of the late second century CE, maintains that sectarians who practice polygamy have "fallen away from the truth" ("Against Heresies" 1.28).

Scheidel p.21

Tertullian, a Christian writer from North Africa in the early third century CE, composed a treatise called "On Monogamy" (De Monogamia). This text is an extended argument in favor of monogamy, defined in this case not merely as the absence of multiple unions but also as the rejection of remarriage (i.e., of serial monogamy). It invokes the case of Adam and Eve as a normative model set by God at creation (4.2: "He said, 'It is not good for the man that he be alone; let us make an help-meet for him.' For He would have said 'helpers' if He had destined him to have more wives;" 4.3: '''And two shall be (made) into one flesh' - not three, nor more; else they would be no more 'two' if (there were) more"), and likewise the pairing of creatures rescued on Noah's Ark (4.7: "Even unclean birds were not allowed to enter with two females each"). He interprets the passages in Mark and Matthews discussed in Section 8.2 as evidence in support of normative monogamy and rejects the relevance of the Jewish patriarch Abraham's reported bigamy (6).

Around 300 CE, bishop Methodius claimed that "the contracting of marriage with several wives had been done away with from the times of the prophets" and that "'Let your fountain be blessed and rejoice in the wife of your youth' [= "Proverbs" 5.18]. This plainly forbids a plurality of wives" ("Marcella" 3).

Spread out over a century and a half, these few statements indicate that polygamy was not a significant concern for Christian thinkers during this period. They tended to be more preoccupied with remarriage, a topic that was already the main focus of Tertullian's treatise and was later considered a transgression worthy of serious penalties, for example by the fourth-century CE bishop Basil who endorsed excommunication for one year for a second marriage and of several years for a third one ("To Amphilochius Concerning the Canons," Letter 188). This logically implies that concurrent plural marriage, i.e. polygamy, was considered even worse, or at any rate that it would have attracted greater opprobrium if it had been more common. The scarcity of explicit references to this custom appears to be a function of its low incidence within much of the Roman Empire, whereas remarriage ofwidow(er)s or divorcees was much more widespread and therefore considered worthy of attention.

I conclude this survey of the ancient Christian tradition with Augustine of Hippo (later canonized as Saint Augustine) who was one of the most prolific Christian authors of the Roman period and through his writings later on exerted tremendous influence on medieval Christian thought. In a treatise entitled "On the Good of Marriage" (De Bono Coniuga/i), composed in the early fifth century CE, he expressly identifies the prohibition of polygamy as a "Roman custom:"

"And yet it [i.e., remarriage after divorce 1 is not allowed; and now indeed in our times, and according to Roman custom, neither to marry in addition, so as to have more than one wife living.,,39

Augustine returns to the importance of custom in a separate assessment of the polygamous unions ascribed to Jacob in the Old Testament:

"Again, Jacob the son of Isaac is charged with having committed a great crime because he had four wives. But here there is no ground for a criminal accusation: for a plurality of wives was no crime when it was the custom;

39 "On the Good of Marriage" 7. The original text reads "et tamen non licet, et nostris quidem iam temporibus ac more Romano nee superducere, ut ampHus habeat quam unam vivam."

Scheidel p.22

and it is a crime now, because it is no longer the custom" ("Against Faustus" 22.47).40

In other writings, Augustine explains instances of polygamy encountered in the Old Testament tradition with reference to the need for population growth.41 Thus, he reckoned that at the time of Jacob, "in order to multiply posterity, no law forbade a plurality of wives" ("The City of God" 16.38). Likewise, in the case of Abraham's bigamy, "the pious desire for the procreation of children was an indication of the absence of criminal indulgence" ("Against Faustus" 22.31 ).42 Monogamy is merely presented as a preferred option, in keeping with the example set by Adam and Eve:

"That the good purpose of marriage, however, is better promoted by one husband with one wife, than by a husband with several wives, is shown plainly enough by the very first union of a married pair, which was made by the Divine Being Himself, with the intention of marriages taking their beginning therefrom, and of its affording to them a more honorable precedent" ("On Marriage and Concupiscence" 1.10). In contrast to earlier writers, Augustine does not present monogamy as a divine

ordinance but explains its earlier existence and later rejection in pragmatic terms, with reterence to custom and, indeed, even to Roman custom. His perspective underlines the degree of variability in Christian perspectives on this topic during the formative stages of Christianity.

8.4 Concluding Assessment

In conclusion, it must be noted that no Christian authorities from antiquity whose own writings survive ever approved of polygamous practice and that all of them required monogamous practice for their own period of writing, often in the enhanced form of rejecting serial monogamy as well. The inclusion of Jewish scripture into the Christian canon in the form of the Old Testament presented Christian writers with the challenge of having to explain or justifY polygamous practices reported in those texts. Within what we might call mainstream Christianity (i.e., the traditions that prevailed over alternative viewpoints and generated the surviving textual record), this engagement with prior Jewish practice never resulted in acceptance of polygamous practice in the present.

The foundational core texts of Christianity, dating from the first century CE and subsequently enshrined in the New Testament, do not explicitly and unequivocally enjoin monogamy or condemn polygamy, except with respect to community leaders, but

40 The passage continues: "There are sins against nature, and sins against custom, and sins against the laws. In which, then, of these senses did Jacob sin in having a plurality of wives? As regards nature, he used the women not for sensual gratification, but for the procreation of children. For custom, this was the common practice at that time in those countries. And for the laws, no prohibition existed. The only reason of its being a crime now to do this, is because custom and the laws forbid it." "Clark 1986: 147. For similar sentiments in other Christian writers, see Brundage 1987: 66. " Conversely, only Old Testament polygamy for the sake of sexual gratification was to be deemed an aberration: "To pious and discerning readers of the sacred Scriptures evidence of the chastity of the holy men who are said to have had several wives is found in this, that Solomon, who by his polygamy gratified his passions, instead of seeking for offspring, is expressly noted as chargeable with being a lover of women. This, as we are informed by the truth which accepts no man's person, led him down into the abyss of idolatry" ("Against Faustus" 22.81).

Scheidel p.23

implicitly and logically reject polygamous practices. Moreover, several early Christian theologians from the second and third centuries CE expressly and vehemently reject polygamy in a generalizing fashion. It is impossible to establish with certainty whether their stance represents a mere clarification of earlier positions or entails actual modifications in doctrine. To complicate matters, it must be borne in mind that the early Christian movement was thoroughly decentralized, dispersed across the Roman world and beyond in a growing number of mostly small-scale cellular communities, and that any given text cannot therefore be taken to represent a binding or orthodox position representative of Christianity as a whole.

After several centuries of Christian writing, Augustine presents an assessment of monogamy that privileges pragmatic considerations and, on one occasion, identifies monogamy as a Roman (in the sense of pre- or non-Christian) custom. While this does not qualify the rejection of polygamy earlier theologians had advocated on doctrinal grounds, it serves as a reminder of the dual context of the development of ancient Christianity, namely Jewish and Greco-Roman. Christianity'S origins as an unorthodox movement within the Jewish belief system may have made polygamy a potentially contentious issue, given that the majority of the earliest converts to Christianity were Jewish and that polygamy was not banned in that particular culture. Over time, as Christianity turned into an effectively and formally separate religious organization, it evolved and expanded primarily within the context of a Mediterranean society that was dominated by cultures (Greek and Roman) that had long been practicing SIUM. Both the increasing autonomy of Christianity from Judaism and its expansion away from the Middle East and into the core regions of prescriptively monogamous Greco-Roman civilization would have induced Christians to embrace and internalize monogamous practices even if they had not already been present from the beginning.

All this makes it difficult to give a straightforward answer to the question to what extent monogamy can be said to be a "Judeo-Christian" concept. It is clear that it was not a normative "Judean" concept, at least as far as the dominant or hegemonic strands of Jewish culture in antiquity are concerned. By contrast, SlUM was certainly a firmly-held principle of the Christian Church by the time the Roman state sought to co-opt the Christian leadership in the fourth century CE, and the surviving record shows that it had already been a common expectation in the second and third centuries CEo Given the nature of the development of early Christianity and the nature of the evidence, the two possible roots of Christian monogamy - religious doctrine and Greco-Roman practice -cannot be neatly disentangled. Put in simplified terms, we have to choose between two different scenarios. (l) Earliest Christianity may have been ideologically committed to SlUM right from the start and may in that regard have resembled other dissident movements within Judaism, such as the Essene community documented at Qumran (see Section 8.1). (2) Alternatively, the generalized affirmation of SlUM may have been the result of a more protracted formative process that may have been significantly influenced by prescriptively monogamous norms in the Roman world.

In my professional judgment, the first of these scenarios is more plausible for the following reason. It is useful to consider a counterfactual. If Christianity had first emerged in a part of the Roman Empire where SIUM had long been legal and/or social practice and had advocated monogamy, it would be impossible for us to determine whether Christian monogamous norms were the product of specific religious beliefs or

Scheidel p.24

the consequence of the adoption and internalization of prevailing societal norms. In that case, the question would be moot because Christian norms would simply match societal norms and it would effectively be impossible to distinguish between them. In that case, prescriptive monogamy could not meaningfully be identified as a specifically religious element of the Christian belief system.

In reality, however, Christianity first arose in the context of Jewish society and religion in the Levant, where polygamy was acceptable and at least occasionally practiced. Therefore, normative rejection of polygamy was not a given, not merely a background feature of local society. In as much as earliest Christianity can be shown to have been prescriptively monogamous, it distinguished itself from Jewish traditions of latent or actual polygamous practice. As I have tried to show in Section 8.2, key foundational texts logically and implicitly extol monogamous principles and reject polygamy, even though polygamy was legitimate and practiced in Jewish society at that time. This sets early Christian teachings apart from dominant local societal norms. Yet implicit Christian rejection of polygamy was not a unique feature within Jewish culture: we find more far more explicit condemnations of polygamy - justified in religious terms - in the contemporaneous Jewish Qumran tradition (see Section 8.2). Rejection of polygamy is therefore best seen as a characteristic associated with dissident or reform movements within the Jewish belief system, of grass-root movements that opposed traditional manifestations or perceived excesses of elite privilege, such as polygamy. In that respect, these movements echo the apprehensions about polygamy that already colored accounts of this practice in the Old Testament tradition (see Section 8.1).

Early Christian monogamy may consequently be understood as a feature of unorthodox doctrines that emerged within the Jewish belief system and Jewish society. These doctrines, although they may well have been shaped by socio-economic concerns, may be defined as religious in nature given that they were advocated with explicit reference to religious scripture (the Old Testament). In this sense, which can only be established contextually, Christian insistence on SlUM and rejection of polygamy can legitimately be defined as religious precepts.

At the same time, it is important to appreciate that as Christianity expanded beyond the Jewish communities in the Levant, it did so within an imperial state that was dominated by prescriptively monogamous cultures and regimes. In this environment, SlUM was by no means a novel or unusual feature that would have been regarded as a quintessentially Christian norm or practice. There is therefore no reason to assume, and no evidence to support the assumption, that during the remainder of the Roman period, from the first to the fifth centuries CE, SlUM was viewed as a specifically Christian characteristic. The fact that Christian norms and more general societal norms coincided throughout much of the Roman world makes it dit1icult to define Christian insistence on SlUM as a specifically religious norm, even though, as I have argued, it can be defined as such with respect to its origin.

Conditions changed with the failure of the Roman Empire from the fifth to seventh centuries CEo The Muslim Arab expansion into the Middle East, North Africa and Spain introduced or re-introduced polygamous practice to parts of the former Roman Empire, which by then had undergone at least nominal Christianization on a large scale. The expansion of Islamic beliefs and practices in these regions would have served to accentuate the Christian dimension of SlUM which, no longer simply matching secular

Scheidel p. 25

50

law and custom, was bound to be seen as a more specifically Christian practice. A similar process of accentuation occurred in western Europe, which came to be settled or ruled by only recently and/or superficially Christianized conquest regimes (Germans, later Slavs, Norse, and Eurasian steppe nomads). For these groups, SlUM was not established practice in the same way as it had been for the ancient Greeks and Romans. As a result, insistence on SlUM and rejection of polygamy became more specifically associated with Christianity and the Christian Church or Churches. The latter's attempts to impose SlUM on these populations is documented in medieval church legislation and commentary (Bnmdage 1987, index s.v. "polygyny").

Eventually, as effective Christianization progressed during the Middle Ages, SlUM once again came to be seen as both a Christian and a European or, later, "western" custom, and distinctions between SlUM as a normatively religious precept and SlUM as effective societal practice once again became less meaningful, as they had already been in the Roman period. However, unlike in the Roman period, when SlUM had already been dominant as Christianity arrived on the scene and cannot therefore be considered as a result of Christianization, the re-consolidation and eventual dominance of SlUM in medieval and modern Europe and the wider "West" not only reflected long-term continuities in societal practice from the Roman to the post-Roman periods but was also, at least in part, the result of the Christian leadership's efforts to impose SlUM as an ideally universal norm and practice.

As already noted, the congruence between Christian and pre-existing societal norms and practices regarding monogamous unions in the Roman period and to a growing extent also in subsequent periods makes it difficult to define western SlUM neatly as a predominantly religious or secular phenomenon. If the ideational origins of Christian doctrine concerning monogamy are considered to be the decisive criterion for establishing such a definition, it is legitimate, in a narrow technical sense, to define western SlUM as a Christian norm. This interpretation receives further support from Christianity'S role in the re-consolidation of SlUM following the failure of the Roman Empire. However, SlUM cannot be regarded as an inherently distinctive or novel feature of the Christian belief system because it coincided with widespread societal norms and practices when it expanded and was institutionalized during the Roman period and later.
