'''Polygyny''' ({{IPAc-en|p|ə|ˈ|l|ɪ|dʒ|ɪ|n|i}}) is a form of [[polygamy]] entailing the marriage of a man to several women. The term polygyny is from [[Neoclassical Greek]] πολυγυνία ({{grc-transl|πολυγυνία}}); {{etymology|grc|''{{wikt-lang|grc|πολύ}}'' ({{grc-transl|πολύ}})|many||''{{wikt-lang|grc|γυνή}}'' ({{grc-transl|γυνή}})|woman, wife}}.<ref>''[[A Greek–English Lexicon]]'', Liddell & Scott, [[wikt:s.v.|s.v.]] γυνή</ref>

==Incidence==
Polygyny is more widespread in [[Africa]] than in any other [[continent]].<ref>Clignet, R., ''Many Wives, Many Powers'', Northwestern University Press, Evanston (1970), p. 17.</ref> Some scholars theorize that the [[History of slavery|slave trade]]'s impact on the male-to-female sex ratio was a key factor in the emergence and fortification of polygynous practices in regions of Africa.<ref name="dalton" />

Polygyny is most common in a region known as the "polygamy belt" in [[West Africa]] and [[Central Africa]], with the countries estimated to have the highest polygamy prevalence in the world being [[Burkina Faso]], [[Mali]], [[Gambia]], [[Niger]] and [[Nigeria]].<ref name="pewresearch.org">{{cite web |last1=Kramer |first1=Stephanie |title=Polygamy is rare around the world and mostly confined to a few regions |url=https://www.pewresearch.org/short-reads/2020/12/07/polygamy-is-rare-around-the-world-and-mostly-confined-to-a-few-regions/ |website=Pew Research Center |date=December 7, 2020}}</ref> In the region of [[sub-Saharan Africa]], polygyny is common and deeply rooted in the culture, with 11 percent of the population of sub-Saharan Africa living in such marriages (25 percent of the Muslim population and 3 percent of the Christian population, as of 2019).<ref name="pewresearch.org"/> Polygyny is especially widespread in West Africa, with the countries estimated to have the highest polygyny prevalence in the world as of 2019 being Burkina Faso (36%), Mali (34%) and Gambia (30%).<ref name="pewresearch.org"/> Outside of Africa, the highest prevalence is in [[Afghanistan]], [[Yemen]] and [[Iraq]].
<ref name="pewresearch.org"/>

Polygyny was accepted in ancient [[Hebrews|Hebrew]] society, in [[Ancient China|classical China]], and in some traditional Native American, [[Africa]]n and [[Polynesia]]n cultures. In the [[Indian subcontinent]], it was known to have been practiced during ancient times.{{Citation needed|date=July 2024|reason=polygyny is legal today  in Bangladesh for Hindus as well as muslims. In Pakistan and India  it is legal for muslim men to have upto four wives with certain conditions }} It was accepted in [[Ancient Greece]], until the [[Roman Empire]] and the [[Catholic Church]]. {{Citation needed|date=October 2023}}

In [[North America]], polygyny is practiced by some Mormon sects, such as the [[Fundamentalist Church of Jesus Christ of Latter-Day Saints]] (FLDS Church).<ref>{{Cite web | url=http://archive.sltrib.com/printfriendly.php?id=2925222&itype=NGPSID | title=LDS splinter groups growing &#124; the Salt Lake Tribune}}</ref><ref>{{Cite news | url=https://www.bbc.com/news/world-us-canada-40709250 | title=Canadian polygamists found guilty| work=BBC News| date=2017-07-25}}</ref>

Polygyny is more common in societies that have the custom of [[bride price]].<ref name=Oxford2007>''The Oxford Handbook of Evolutionary Psychology'', Edited by Robin Dunbar and Louise Barret (2007). Oxford University Press, Chapter 26, "The evolutionary ecology of family size".</ref>

Some studies of [[mitochondrial DNA]] have shown that there have been more mothers than fathers in the genetic record of the human species, meaning that the proportion of females that have reproduced in each generation has generally been greater than the proportion of men that reproduced. The authors of one 2014 study attributed these findings to widespread polygyny.<ref name=MoreMothers>{{cite web |last1=Geggel |first1=Laura |title=Humanity Has More Mothers Than Fathers, DNA Reveals |url=https://www.livescience.com/47976-more-mothers-in-human-history.html |website=livescience.com |access-date=1 March 2023 |language=en |date=24 September 2014}}</ref>

==Cause and explanation==
===Augmenting division of labor===
[[Ester Boserup]] was the first to propose that the high incidence of polygyny in sub-Saharan Africa is rooted in the sexual division of labor in [[hoe-farming]] and the large economic contribution of women.<ref name="goody" />{{sfn|Boserup|1970}}
 
{{Anthropology of kinship}}

In some regions of shifting cultivation where polygyny is most frequently recorded, labor is often starkly divided between genders. In many of these cases, the task of felling trees in preparation of new plots, the fencing of fields against wild animals, and sometimes the planting of crops, is usually done by men and older boys (along with hunting, fishing and the raising of livestock).<ref name="FB 1969">Guyer, Jane. (1991). "Female Farming in Anthropology and African History". ''Gender at the Crossroads of Knowledge: Feminist Anthropology in the postmodern Era''. Berkeley and Los Angeles, California: University of California Press. pp. 260-261.</ref><ref name="Cornwall2005">{{cite book|author=Andrea Cornwall|title=Readings in Gender in Africa|url=https://books.google.com/books?id=INci71MNlhQC&pg=PA103|date=2005|publisher=Indiana University Press|isbn=978-0-253-34517-2|pages=103–110}}</ref> Wives, on the other hand, are responsible for other aspects of cultivating, food processing and providing meals and for performing domestic duties for the family. Boserup argues that though women's work comprises a larger percentage of tasks that form the basis of sub-Saharan life, women often do not receive the majority portion of the benefits that accompany economic and agricultural success.

{{Close relationships}}

An elderly cultivator, with several wives and likely several young male children, benefits from having a much larger workforce within his household. By the combined efforts of his young sons and young wives, he may gradually expand his cultivation and become more prosperous. A man with a single wife has less help in cultivation and is likely to have little or no help for felling trees. According to Boserup's historical data, women living in such a structure also welcome one or more co-wives to share with them the burden of daily labor. However, the second wife will usually do the most tiresome work, almost as if she were a servant to the first wife, and will be inferior to the first wife in status.{{sfn|Boserup|1970|pp=41–47}} A 1930s study of the [[Mende people|Mende]] in the West African state of Sierra Leone concluded that a plurality of wives is an agricultural asset, since a large number of women makes it unnecessary to employ wage laborers.{{sfn|Little|1967}} Polygyny is considered an economic advantage in many rural areas. In some cases, the economic role of the additional wife enables the husband to enjoy more leisure.{{sfn|Boserup|1970|pp=40–41}}

Anthropologist [[Jack Goody]]'s comparative study of marriage around the world, using the [[Human Relations Area Files|Ethnographic Atlas]], demonstrated a historical correlation between the practice of extensive [[shifting cultivation]] and polygyny in many Sub-Saharan African societies.<ref name=goody>{{cite book|last=Goody|first=Jack|title=Production and Reproduction: A Comparative Study of the Domestic Domain|date=1976|publisher=Cambridge University Press|location=Cambridge|pages=27–29}}</ref> Drawing on the work of [[Ester Boserup]], Goody notes that in some of the sparsely populated regions where shifting cultivation takes place in Africa, much of the work is done by women. This favored polygynous marriages, in which men sought to monopolize the production of women "who are valued both as workers and as child bearers."

Goody, however, observes that the correlation is imperfect, and also describes more traditionally male-dominated though relatively extensive farming systems, such as those common in much of West Africa, particularly the [[savanna]] region, where more agricultural work is done by men, and polygamy is desired more for the production of male offspring whose labor in farming is valued.<ref>Goody, Jack. ''Polygyny, Economy and the Role of Women. In The Character of Kinship''. London: Cambridge University Press, 1973, p. 180–190.</ref>

Goody's observation regarding African male farming systems is discussed and supported by anthropologists Douglas R. White and Michael L. Burton in their article, "Causes of Polygyny: Ecology, Economy, Kinship, and Warfare",<ref name="white 1988">{{cite journal | last1=White | first1=Douglas | last2=Burton | first2=Michael | date=1988 | title=Causes of Polygyny: Ecology, Economy, Kinship, and Warfare |url= https://escholarship.org/uc/item/0468q4xq | journal=American Anthropologist | volume=90| issue=4| pages=871–887 | doi=10.1525/aa.1988.90.4.02a00060}}</ref>{{rp|884}} where the authors note: "Goody (1973) argues against the female contributions hypothesis. He notes Dorjahn's (1959) comparison of East and

West Africa, showing higher female agricultural contributions in East Africa and higher polygyny rates in West Africa, especially in the West African savanna, where one finds especially high male agricultural contributions. Goody says, "The reasons behind polygyny are sexual and reproductive rather than economic and productive" (1973:189), arguing that men marry polygynously to maximize their fertility and to obtain large households containing many young dependent males."<ref name="white 1988" />{{rp|873}}<ref name="White2">{{cite journal | vauthors=White DR, Burton ML, Dow MM| title=Sexual Division of Labor in African Agriculture: A Network Autocorrelation Analysis | journal = American Anthropologist | volume=83 | issue=4 | pages=824–849 | date=December 1981 | doi=10.1525/aa.1981.83.4.02a00040 | url= https://www.researchgate.net/publication/227632381 | doi-access=free }}</ref>

An analysis by James Fenske (2012) found that child mortality and ecologically-related economic shocks had a stronger association with rates of polygamy in Sub-Saharan Africa rather than female agricultural contributions (which are typically relatively small in the West African savanna and Sahel, where polygyny rates are higher), finding that polygyny rates decrease significantly in line with child mortality rates.<ref>{{Citation | last=Fenske | first=James | title=African Polygamy: Past and Present |url= https://www.economics.ox.ac.uk/materials/papers/12544/csae-wps-2012-20.pdf | publisher=Centre for the Study of African Economies, University of Oxford | pages=1–30 | date=November 2012 | access-date=2019-09-27 | archive-date=2017-09-22 | archive-url= https://web.archive.org/web/20170922005828/https://www.economics.ox.ac.uk/materials/papers/12544/csae-wps-2012-20.pdf }}</ref>

===Desire for progeny===
Most research into the determinants of polygyny has focused on macro-level factors. Widespread polygyny is linked to the kinship groups that share descent from a common ancestor.<ref name="Timeas 1998">Timeas, Ian and Reyner, Angela. "[http://blogs.lshtm.ac.uk/iantimaeus/files/2012/04/Polygyny.pdf Polygynists and Their Wives in Sub-Saharan Africa: An Analysis of Five Demographic and Health Surveys]". ''Population Studies'' 52:2 (1998)</ref> Polygyny also served as "a dynamic principle of family survival, growth, security, continuity, and prestige", especially as a socially approved mechanism that increases the number of adult workers immediately and the eventual workforce of resident children.<ref name="Gwako, Edwins Laban 1998"/>

According to scientific studies, the human mating system is considered to be moderately polygynandrous (multiple males and multiple females, all mate with each other), based both on surveys of world populations,<ref>{{cite journal |last1=Low |first1=Bobbi S. |title=Measures of Polygyny in Humans |journal=Current Anthropology |date=February 1988 |volume=29 |issue=1 |pages=189–194 |doi=10.1086/203627 |s2cid=143665535 |url=https://www.journals.uchicago.edu/doi/abs/10.1086/203627|url-access=subscription }}</ref><ref>Murdock G.

===Economic burden===
Scholars have argued that in farming systems where men do most of the agriculture work, a second wife can be an economic burden rather than an asset. In order to feed an additional wife, the husband must either work harder himself or he must hire laborers to do part of the work. In such regions, polygyny is either non-existent or is a luxury which only a small minority of rich farmers can indulge.{{sfn|Boserup|1970|pp=47–48}}

A report by the secretariat of the UN Economic Commission for Africa (ECA) quotes: "one of the strongest appeals of polygyny to men in Africa is precisely its economic aspect, for a man with several wives commands more land, can produce more food for his household and can achieve a high status due to the wealth which he can command".{{sfn|Boserup|1970|p=37}} In Boserup's 1970 discussion of earlier analyses of polygynous systems, for example that of Little's work of the 1930s,{{sfn|Little|1967}} that through the hard work, economic, and agricultural assistance of a man's several wives, a husband could afford to pay the bride price of a new wife and further his access to more land, meanwhile increasing his progeny.{{sfn|Boserup|1970|pp=37–40}} According to Boserup, writing in 1970, tribal rules of land tenure were still in force over much of the continent of Africa.{{sfn|Boserup|1970|p=37}} In this system, members of a tribe which commands a certain territory had a native right to take land under cultivation for food production, and in many cases, also for the cultivation of cash crops. Under this tenure system, an additional wife is an economic asset that helps the family to expand its production.

The economist [[Michèle Tertilt]] concludes that countries that practice polygyny are less economically stable than those that practice [[monogamy]]. Polygynous countries usually have a higher fertility rate, fewer savings reserves, and a lower GDP. A 2014 study estimates that fertility would decrease by 40 percent, savings would increase by 70 percent and GDP would increase by 170 percent if polygyny were banned.<ref name="dalton">{{Cite journal|last1=Dalton|first1=John|last2=Leung|first2=Tin Cheuk|date=2014|title=Why Is Polygyny More Prevalent in Western Africa?

Despite the expenses of polygynous marriages, a 1995 study suggests that men benefit from marrying multiple wives through the economic and social insurance that [[kinship]] ties produce. With a large network of in-laws, these men have the ties they need to compensate for other economic shortages.<ref>{{Cite journal|last=Jacoby|first=Hanan|date=1995|title=The Economics of Polygyny in Sub-Saharan Africa: Female Productivity and the Demand for Wives in Côte d'Ivoire|journal=Journal of Political Economy|volume=103|issue=5|pages=942–943|doi=10.1086/262009|s2cid=153376774}}</ref>

===Libido===
Some analysts have posited that a high [[libido]] may be a factor in polygyny,<ref>{{cite book|last1=Kammeyer|first1=Kenneth|title=Confronting the issues: Sex roles, marriage, and the family|url=https://archive.org/details/confrontingissue00kamm|date=1975|page=[https://archive.org/details/confrontingissue00kamm/page/117 117]|publisher=Allyn and Bacon |isbn=978-0-205-04813-7}}</ref> although others have downplayed its significance.<ref>{{cite book|last1=Baber|first1=Ray|title=Marriage and the Family|date=1939|page=38}}</ref> The sex drive as a factor in some Asian cultures was sometimes associated with wealthy men and those that were adjunct to an aristocracy,<ref>{{cite book|last1=Thomas|first1=Paul|title=Indian Women Through the Ages: A Historical Survey of the Position of Women and the Institutions of Marriage and Family in India from Remote Antiquity to the Present Day.

In this case, it would be hard to determine whether the origin was that of high libido, as polygyny would be practiced regardless. Other explanations postulate that polygyny is a tool used to ward off inclinations towards infidelity.<ref>{{cite journal|last1=Balon|first1=R|title=Is Infidelity Biologically Determined?|journal=European Psychiatry|volume=30|date=2015|page=72|doi=10.1016/S0924-9338(15)30061-4|s2cid=141975947}}</ref> In a chapter comparing Sub-Saharan African polygyny, Boserup (1970) comments that in regions where polygyny is practiced, but for demographic and economic reasons must to be delayed for males until older ages, higher incidences of adultery and prostitution are expected to be present.{{sfn|Boserup|1970|p=44}}

Polygyny in West Africa, the region of the world where the practice is most common, exists in a societal context where historical factors, such as the slave trade, and the local religion, Islam, interact creating a culture where polygyny is widespread. The slave trade's impact on the male-to-female sex ratio has been cited as a key factor in the high prevalence of polygynous practices in this region of Africa.<ref name="dalton" />

In a 2011 doctoral thesis, anthropologist Kyle R.

===Effects on women===
Inequality between husbands and wives is common in countries where polygyny is more frequently practiced because of limited education. In Africa polygyny was believed to be part of the way to build an empire. It was not until the post-colonialism era in Africa that polygyny began to be viewed as unjust or taboo. According to Natali Exposito, "in a study of the Ngwa Igbo Clan in Nigeria identified five principal reasons for men to maintain more than one wife: because having more than one wife allows the Ngwa husband to (1) have the many children that he desires; (2) heighten his prestige and boost his ego among his peers; (3) enhance his status within the community; (4) ensure a sufficient availability of labor to perform the necessary farm work and the processing of commercial oil-palm produce; and (5) satisfy his sexual urges."<ref>{{Cite journal|last=Exposito|first=Natali|date=2017|title=The Negative Impact of Polygamy on Women and Children in Mormon and Islamic Cultures|journal=Seton Hall University Law School Student Scholarship|url= http://scholarship.shu.edu/cgi/viewcontent.cgi?article=1898&context=student_scholarship| archive-url = https://web.archive.org/web/20170219030849/http://scholarship.shu.edu/cgi/viewcontent.cgi?article=1898&context=student_scholarship| archive-date= 19 February 2017}}</ref> Out of all of the reasons stated none are beneficial to the wives, but instead only beneficial to the husbands. In Egypt, feminists have fought for polygamy to be abolished, but it is viewed as a core component of [[Islamic family jurisprudence|Islamic family law]], and has thus been largely unsuccessful. In countries where polygyny is practiced less frequently, women have more equality in the marriage and are better able to communicate their opinions about family planning.<ref name=":1">{{Cite journal|last1=Al-Krenawi|first1=Alean|last2=Graham|first2=John|date=2011|title=A Comparison Study of Psychological Family Function Marital Satisfaction of Polygamous and Monogamous women in Jordan|journal=Community Mental Health Journal|volume=47|issue=5|pages=594–602|pmid=21573772|doi=10.1007/s10597-011-9405-x|s2cid=11063695}}</ref>

Women participating in polygynous marriages share common marital problems with women in a monogamous marriage; however, there are issues uniquely related to polygyny which affects their overall [[life satisfaction]] and have severe implications for women's health.<ref name=":2" /> Women practicing polygyny are susceptible to sexually transmitted infections, infertility, and mental health complications.<ref name=":1" /> Among the Logoli of [[Kenya]], the fear of [[AIDS]] or becoming infected with the [[HIV]] virus has informed women's decisions about entering polygynous marriages. Some view polygyny as a means to prevent men from taking random sexual partners and potentially introducing STIs into relationships. Interviews conducted with some of the Logoli tribe in Kenya suggested they feared polygynous marriages because of what they have witnessed in the lives of other women who are currently in such relationships. The observed experiences of some of the women in polygynous unions tend to be characterized by frequent jealousy, conflicts, competition, tensions, and psychological stresses. Some of the husbands fail to share love and other resources equally; and envy and hatred, and sometimes violent physical confrontations become the order of the day among co-wives and their children. This discourages women from entering a polygynous marriage.<ref name="Gwako, Edwins Laban 1998">Gwako, Edwins Laban. "Polygamy Among the Logoli of Western Kenya". ''Anthropos'' 93.4 (1998). Web.</ref> Research shows that competition and conflict can intensify to unbearable level for co-wives causing women to commit [[suicide]] due to psychological distress. Findings show that the wife order can affect life satisfaction. According to Bove and Valeggia, women who are senior wives often misuse their position to obtain healthcare benefits in countries where only one wife can become a recipient. The conflict between co-wives can attribute to the higher rates of mental health disorders and issues such as anxiety, depression, [[somatization]], [[psychoticism]], and paranoia. As well as this reduced marital/life satisfaction and low self-esteem has been shown to be more prevalent among women in polygynous relationships when compared to women in monogamous relationships.<ref name=":2">{{Cite journal|last1=Bove|first1=Riley|last2=Valeggia|first2=Claudia|date=2009|title=Polygyny and Women's Health in Sub-Saharan Africa|journal=Social Science and Medicine|volume=68|issue=1|pages=21–29|doi=10.1016/j.socscimed.2008.09.045|pmid=18952335}}</ref><ref>{{Cite journal|journal=Epidemiology and Psychiatric Sciences |volume=2|issue=1|pages=47–62|last=Shepard|first=L.D.|title=The impact of polygamy on women's mental health: a systematic review|date=2013|doi=10.1017/S2045796012000121|pmid=22794315|pmc=6998378}}</ref>

Various methods have been used to reduce the amount of jealousy and conflict among wives. These include sororal polygyny, in which the co-wives are sisters; and hut polygyny, in which each wife has her own residence and the husband visits them in rotation. A clear status hierarchy among wives is also sometimes used to avoid fighting by establishing unequivocally each wife's rights and obligations.<ref name="lee">{{cite book|title=Family Structure and Interaction: A Comparative Analysis|author=Lee, Gary R.|chapter=Structural Variety in Marriage|pages=91–92|edition=2nd, revised|publisher=University of Minnesota Press|date=1982}}</ref> Although there are several harmful aspects of this practice related to women, there are some reported personal and economic advantages for women such as sharing household and child rearing responsibilities. Also, wives share companionship and support with co-wives.<ref name=":1" />

Studies of the Ngwa group in eastern Nigeria shows that on average, women in polygynous unions are 22–26 percent less fertile than women in monogamous unions. Data shows that the greater the intensity of polygyny, the lower the fertility of successive wives: 15 percent deficit for first wives; a 37 percent deficit for second wives; and a 46 percent deficit for third or more wives.<ref name=":4">{{Cite journal|last=Ukaegbu|first=Alfred O.|date=1977|title=Fertility of Women in Polygynous Unions in Rural Eastern Nigeria|journal=Journal of Marriage and Family|volume=39|issue=2|pages=397–404|doi=10.2307/351134 |jstor=351134}}</ref> Studies show that seems to exist because of the widening age gap between the successive order of wives and because of the decreasing exposure to coitus, if all coitus occurs in marriage.<ref>{{Cite journal|last=Ware|first=Helen|date=1979|title=Polygyny: Women's Views in a Transitional Society, Nigeria 1975|journal=Journal of Marriage and Family|volume=41|issue=1|pages=185–195|doi=10.2307/351742 |jstor=351742}}</ref>

=== Disease ===
Studies show there are two mechanisms that could lead to higher prevalence rates of HIV in men and women who are in polygynous unions: partners in polygynous unions have more extra-marital relationships and thus increase each other's exposure to HIV; women who are recruited into a polygynous union are more likely to be HIV positive than those who marry a monogamous husband.<ref name="demog journal">{{Cite journal|last1=Reniers|first1=Georges|last2=Tfaily|first2=Rania|date=2012-08-01|title=Polygyny, Partnership Concurrency, and HIV Transmission in Sub-Saharan Africa|journal=Demography|volume=49|issue=3|pages=1075–1101|doi=10.1007/s13524-012-0114-z|pmid=22661302|s2cid=207472013 |doi-access=free}}</ref> In addition to these two mechanisms, variation in HIV prevalence rates by union type is possibly due to individuals in polygynous unions are typically part of a sexual network with concurrent partnerships.<ref name="demog journal"/>

The ecological association between polygyny and HIV prevalence is shown to be negative at the sub-national level. HIV prevalence tends to be lower in countries where the practice of polygyny is common, and within countries it is lower in areas with higher levels of polygyny. Proposed explanations for the protective effect of polygyny include the distinctive structure of sexual networks produced by polygyny, the disproportionate recruitment of HIV positive women into marriages with a polygynous husband, and the lower coital frequency in conjugal dyads of polygynous marriages.<ref name=":2" />

For example, studies in Malawi have shown that for men and women in polygynous marriages, the rate of HIV is between 10 and 15 percent.<ref name="demog journal"/> About 14 percent of Malawi's population is infected with HIV, which causes AIDS, according to official figures.

===Criticism===
Criticism of polygyny focuses on the wellbeing of the wives in such marriages, including coercion, buying and selling of wives (such as through [[bride price]], which is common in societies that practice polygyny<ref>{{Cite book|url=https://archive.org/details/debtfirst5000yea00grae/page/131|title=Debt: The First 5,000 Years|last=Graeber|first=David|publisher=Melville House|date=2011|isbn=978-1-933633-86-2|pages=[https://archive.org/details/debtfirst5000yea00grae/page/131 131–132]}}</ref>), concerns about inequality and the fate of the young men left without wives (such as the [[Lost boys (Mormon fundamentalism)|lost boys in the FLDS Church]]), as well as the relation between polygyny practiced on a large scale in a society and war.<ref>{{Cite news|url=https://www.economist.com/the-economist-explains/2018/03/19/why-polygamy-breeds-civil-war|title = Why polygamy breeds civil war|newspaper = The Economist}}</ref>

A notable critic of polygyny was [[Thomas Aquinas]] nearly eight centuries ago. He contended that polygyny is unjust to wives and children.<ref name=":10">{{Cite journal|url=http://law.emory.edu/elj/content/volume-64/issue-6/articles-and-essays/two-flesh-western-monogamy-polygamy.html|title=Why Two in One Flesh?

According to Aquinas, polygyny violates the requirements of fidelity between husband and wife.<ref name=":10" />

Polygyny has been criticized by [[feminism|feminists]] such as Professor John O. Ifediora, who believes that women should be equal to men and not subject to them in marriage. Professor Ifediora also believes that polygyny is a "hindrance to social and economic development" in the continent of Africa due to women's lack of financial control.<ref>{{Cite journal|last=Ifediora|first=John|date=2016|title=Polygamy As Further Subjugation Of African Women, And National Economies|url=http://www.casade.org/polygamy-subjugation-african-women-national-economies/|journal=CASADE|page=1|access-date=2017-04-03|archive-date=2017-04-04|archive-url=https://web.archive.org/web/20170404043456/http://www.casade.org/polygamy-subjugation-african-women-national-economies/}}</ref> Standard polygynist practices often leave women at a disadvantage if they make the decision to remove themselves from the polygynist lifestyle. To leave the marriage, women must repay their bride price. Though this is simple in thought, this is not simple in execution. To prevent their wives from leaving, husbands will often keep the bride price at high levels, which is often at an unpayable level for women.{{sfn|Boserup|1970|p=47}} In most cases, women do not have access to their children if they decide to leave polygyny, nor are they allowed to take them, due to cultural ideas of ownership in relation to progeny. [[Marci Hamilton]] sees polygyny as a form of oppression of women; she wrote: "In polygamy, also not a victimless crime, the practice is built on the subjugation of women to the men's needs and demands. Moreover, for many of the religious polygamists, the women are nothing but the means to a particular doctrinal end – creating more children to increase the man's odds of getting into heaven. Again, the men control the finances and the women are commodities, carrying out the sexual goals of the men. There can be no gender equality in this scenario, which is incapable of being squared with any viable theory of women's rights."<ref>{{Cite web|url=https://supreme.findlaw.com/legal-commentary/the-two-ps-of-gender-inequality-prostitution-and-polygamy-how-the-laws-against-both-are-underenforced-to-protect-men-and-subjugate-women.html|title=The Two 'P's of Gender Inequality: Prostitution and Polygamy – How the Laws Against Both Are Underenforced to Protect Men and Subjugate Women|last=Hamilton|first=Marci A.|date=9 July 2009|website=FindLaw}}</ref> First wives in polygynous marriages are often in a difficult situation, when the law or religious code does not require their consent or input for new wives to be admitted in the marriage, so the first wife is forced to accept any new women brought into the family by the husband and to get along with them.<ref>{{Cite news|url=https://www.reuters.com/article/us-kenya-women-polygamy-insight-idUSKBN1L0009|title = 'Put up and shut up': Polygamy breeds poverty for Kenyan women and children|newspaper = Reuters|date = 15 August 2018}}</ref> Polygyny is criticized because of its asymmetrical, unequal marital arrangement, where the husband has sexual/romantic relations with several women, but the wives can only have such a relation with one man, their husband, which often leads to rigid gender roles in the marriage.<ref>{{cite journal |last1=Brooks |first1=Thom |title=The Problem with Polygamy |journal=Philosophical Topics |date=2009 |volume=37 |issue=2 |pages=109–122 |doi=10.5840/philtopics20093727 |jstor=43154559 |s2cid=53332349 |url=http://dro.dur.ac.uk/10785/1/10785.pdf }}</ref>

A criticism against polygyny is that in almost all cultures and religious communities that practice it, polygyny is the only form of polygamy that is allowed; and, as such, this violates modern principles of equality between men and women, especially as in many such places females having multiple partners is violently punished through [[honor killing]]s and [[stoning]], or discouraged through [[female genital mutilation]].<ref>{{Cite journal|url=http://classic.austlii.edu.au/au/journals/MurdochUeJlLaw/2005/2.html|last=Struensee |first=Vanessa von|title=The Contribution of Polygamy to Women's Impoverishment: An Argument for Its Prohibition|date=2005  |volume=12 |issue=1–2|journal=Murdoch University Electronic Journal of Law}}</ref><ref>{{cite news |title=Somali woman 'with 11 husbands' stoned to death by al-Shabab |url=https://www.bbc.com/news/world-africa-44055536 |work=BBC News |date=9 May 2018 }}</ref><ref>{{cite journal |last1=Akweongo |first1=Patricia |last2=Jackson |first2=Elizabeth F. |last3=Appiah-Yeboah |first3=Shirley |last4=Sakeah |first4=Evelyn |last5=Phillips |first5=James F. |title=It's a woman's thing: gender roles sustaining the practice of female genital mutilation among the Kassena-Nankana of northern Ghana |journal=Reproductive Health |date=1 March 2021 |volume=18 |issue=1 |page=52 |doi=10.1186/s12978-021-01085-z |pmid=33648528 |pmc=7923333 |doi-access=free }}</ref> In the [[United States]], there has been controversy surrounding the [[Fundamentalist Church of Jesus Christ of Latter-Day Saints]] that practices polygyny, after the community has been marred by accusations of [[child sexual abuse]], welfare fraud, and child labor trafficking, that culminated in the [[life imprisonment]] of polygynous leader [[Warren Jeffs]].<ref>{{Cite news |last=Dark |first=Stephen |url=https://www.theguardian.com/society/2017/nov/17/fundamentalist-mormons-sister-wives-homelessness|title=As a polygamist community crumbles, 'sister wives' are forced from homes|work=[[The Guardian]]|date=17 November 2017}}</ref>

==Premodern era==

In Africa, the Americas, and Southeast Asia in the Premodern Era, circa 600&nbsp;BCE – 1600&nbsp;CE, both monogamy and polygyny occurred. Polygyny occurred even in areas of where monogamy was prevalent. Wealth played a key role in the development of family life during these times. Wealth meant the more powerful men had a principal wife and several secondary wives, known as ''resource polygyny''. Local rulers of villages usually had the most wives as a sign of power and status. Conquerors of villages would often marry the daughters of the former leaders as a symbol of conquest. The practice of resource polygyny continued with the spread and expansion of Islam in Africa and Southeast Asia. Children born into these households were considered free. Children born to free or slave concubines were free, but had lesser status than those born to wives. Living arrangements varied between areas. In Africa, each wife usually had their own house, as well as property and animals. In many other parts of the world, wives lived together in seclusion, under one household. A ''[[harem]]'' (also known as a "forbidden area") was a special part of the house for the wives.<ref>Wiesner-Hanks, Merry E. Gender in History: Global Perspectives. 2nd ed., Wiley-Blackwell, 2011.

==By country==
{{Further|Legality of polygamy}}

===Africa===
====Kenya====

Polygynous marriage was preferred among the Logoli and other [[Abalulya]] sub ethnic groups. Taking additional wives was regarded as one of the fundamental indicators of a successfully established man. Large families enhanced the prestige of Logoli men. Logoli men with large families were also capable of obtaining justice, as they would be feared by people, who would not dare to use force to take their livestock or other goods from them. Interviews with some of the contemporary Logoli men and women who recently made polygynous marriages yielded data which suggest that marrying another wife is usually approached with considerable thought and deliberation by the man. It may or may not involve or require the consent of the other wives and prospective wife's parents. A type of "[[surrogate pregnancy]]" arrangement was reported to have been observed, in which some wives who are unable to bear children, find fulfillment in the children and family provided by a husband taking additional wives.<ref>{{cite journal|last=Laban Moogi Gwako|first=Edwins|title=Polygyny among the Logoli of Western Kenya|journal=Anthropos|volume=93|issue=4/6|pages=331–348|quote="... encouraged their husbands to marry other wives so that they may engage themselves and bestow their affection upon the co-wives' children."|jstor=40464835|date=1998}}</ref> Some of the men indicated that they were pressured by their parents to marry another wife, who could contribute additional income to the family. Some of the young polygynous men indicated that they were trapped in polygyny because of the large number of single women who needed and were willing to take them as husbands although they were already married. Most of those second and third wives were older women who had not yet married.<ref name="Gwako, Edwins Laban 1998"/>

====Nigeria====

Customary law, one of the three legal systems in operation in Nigeria (the other two being Nigerian common law and [[Sharia]] law) allows for one man to legally marry more than one woman.

Unlike those marriages recognized by Sharia, there is no limit to the number of legal wives allowed under customary law. Currently polygyny is most common within [[Royal family|royal]] and [[Nobility|noble]] families within the country, and is largely practiced by the tribes native to its north and west. Although far less popular there, it is nonetheless also legal in Nigeria's east and south.

Polygyny varies according to a woman's age, religion and educational experience. Research conducted in the city of Ibadan, the second largest city in Nigeria, shows that non-educated women are significantly more likely (58%) to be in a polygynous union compared to college educated women (4%).<ref name=":4" /> Followers of traditional African religions are expected to have as many wives as they can afford. Muslim men are allowed up to 4 wives and only if they can be provided for and treated equally. Christians are typically (and expected to be) monogamous.<ref name=":4" />

Among the Ngwa group in Eastern Nigeria, studies show that 70% of polygynous marriages consist of illiterate men and women, compared to 53% in monogamous marriages.<ref name=":4" />

==== Malawi ====
While polygynous marriages are not legally recognized under the civil marriage laws of Malawi, customary law affords a generous amount of benefits to polygynous unions, ranging from inheritance rights to child custody.<ref name="sigi">{{Cite news|title=Figures 18 and 2.10. Social institutions and gender index (SIGI)|doi = 10.1787/888933163273}}</ref> It has been estimated that nearly one in five women in Malawi live in polygynous relationships.<ref name="sigi" />

Efforts to abolish the practice and de facto recognition of polygyny have been widely apparent throughout the recent years in Malawi; led mainly by anti-AIDS organizations and feminist groups. An effort led in 2008 to outlaw polygyny in the country was fiercely opposed by Islamic religious leaders, citing the practice as a cultural, religious and pragmatic reality of the nation.<ref>{{Citation|last=Lamloum|first=Olfa|title=Islamonline.

==== South Africa ====
{{Main|Polygamy in South Africa}}
Polygynous marriages are legal under certain circumstances in South Africa. All polygynous marriages entered into in accordance with the provisions of the [[Recognition of Customary Marriages Act]] are legal. Polygyny in South Africa is practiced among the indigenous Bantu ethnic groups of South Africa, and also within the Muslim community. Although it was widespread in ancient times, it is now only common amongst richer men and men of status, such as chiefs and kings, including the former President of the Republic of South Africa, [[Jacob Zuma]].<ref>{{Cite web|date=2021-04-14|title=What's next for Zuma's wives?|url=https://citizen.co.za/lifestyle/entertainment/2473447/whats-next-for-zumas-wives/|access-date=2021-07-28|website=The Citizen|language=en}}</ref> Polygynous marriages of individuals over the age of 15 accounts for approximately 30,000 (0.1%) people in 2001. Both Islamic law and cultural family laws create a system in which Muslim men are encouraged to take up to four wives. Several factors for this include infertility or long-term illness of the first wife, excessive wealth on the part of the husband enabling him to support widowed or divorced mothers, and the economic benefits of large families.<ref name=":8">{{Cite journal|last=Moosa|first=N|date=2009-09-24|title=Polygynous Muslim Marriages in South Africa: Their Potential Impact on the Incidence of HIV/AIDS|journal=Potchefstroom Electronic Law Journal/Potchefstroomse Elektroniese Regsblad|volume=12|issue=3|doi=10.4314/pelj.v12i3.46271 |doi-access=free|hdl=10394/3641|hdl-access=free}}</ref>

Despite the historical and cultural history of polygyny among Muslim South Africans, polygynous unions are officially illegal on the national level in South Africa. After 1994, various laws such as the freedom of religion in the South African Constitution, the ratification of the UN's Convention on the Elimination of All Forms of Discrimination Against Women and a proposed Draft Bill on Muslim Marriages have tackled the issue of Islamic polygynous unions in South Africa.<ref name=":8" />

==== Somalia ====
Polygyny is legal in Somalia and most commonly seen throughout Muslim communities. According to the Muslim tradition, men can have up to four wives. For a man to gain additional wives in Somalia, it must be granted by the court and it has to be proven that the first wife is either imprisoned or infertile.<ref>{{Cite news|url=http://www.voanews.com/english/archive/2007-03/2007-03-12-voa14.cfm|title=Acceptance of Polygamy Slowly Changes in Muslim Africa|date=12 March 2007|work=Voice of America|archive-url=https://web.archive.org/web/20090507024715/http://www.voanews.com/english/archive/2007-03/2007-03-12-voa14.cfm|access-date=18 November 2019|archive-date=2009-05-07}}</ref>

=== Australia ===
Polygyny is not legal in Australia. The Marriage Act of 1961 under section 94 states that any person who knowingly marries another whose marriage is legally ongoing carries out the act of bigamy. The penalty of bigamy is up to five years of imprisonment. The Full Court of the Family Court of Australia ruled on March 6, 2016, that it is illegal to have polygamous marriages. However, foreign marriages that have potential to be polygamous when it was started will be legally recognized in Australia. The court defined a potentially polygamous marriage as if the marriage is not yet polygamous, but if the country where the marriage marginally taken place permits polygamous marriages of either partner to the original marriage at a later date. Indigenous populations of Australia have been noted to engage in polygamous relationships.

{{refimprove section|date=October 2025}}
Many majority-[[Muslim]] countries retain the traditional [[Sharia]], which interprets teachings of the [[Quran]] to permit polygamy with up to four wives.{{cn|date=October 2025}} Exceptions to this include [[Albania]], [[Tunisia]], [[Turkey]], and former [[Soviet republics]]. Though about 70% of the population of Albania is [[Cultural Muslim|historically Muslim]], the majority is non-practicing.{{cn|date=October 2025}} Turkey and Tunisia are countries with overwhelmingly Muslim populations that enforce [[Laïcité|secularist practices]] by law. In the former Soviet republics, a prohibition against polygamy has been inherited from [[Law of the Soviet Union|Soviet law]]. In the 21st century, a revival of the practice of polygamy in the [[Muslim world]] has contributed to efforts to re-establish its legality and legitimacy in some countries and communities where it is illegal.{{cn|date=October 2025}}

Proposals have been made to re-legalize polygamy in other ex-Soviet Muslim republics, such as [[Kazakhstan]], [[Azerbaijan]] and [[Uzbekistan]].<ref>{{citation |url= http://www.atimes.com/atimes/Central_Asia/GB04Ag01.html |archive-url= https://web.archive.org/web/20050207064554/http://www.atimes.com/atimes/Central_Asia/GB04Ag01.html |url-status= unfit |archive-date= February 7, 2005 |last= Saidazimova |first= Gulnoza|title= Polygamy hurts – in the pocket |newspaper= [[Asia Times Online]] |date= February 4, 2005 }}</ref>

====India====
[[Polygyny in India|Polygamy in India]] is, in general, prohibited and the vast majority of marriages are legally monogamous. Polygyny among Christians was banned in the late 19th century, while [[The Hindu Marriage Act, 1955]] banned polygyny for Hindus. Currently, polygyny is only allowed among [[Muslims]]; but it is strongly discouraged by public policy.<ref>{{Cite web |date=18 May 2021 |title=Polygamy under Muslim Law |url=https://www.ejusticeindia.com/polygamy-under-muslim-law/ |access-date=24 June 2024}}</ref> Muslims are subject to the terms of ''The Muslim Personal Law (Shariat) Application Act of 1937'', interpreted by the [[All India Muslim Personal Law Board]]. Prevalence of polygyny in India is very low: among married women, only 1.68 percent of Hindus, 2.45 percent of Muslims, 2.16 percent of Christians, and 1.16 percent of other religions live in polygynous marriages.<ref>{{cite web |url=http://paa2011.princeton.edu/papers/111406 |title=Bigamy in India: Finding from National Family Health Survey |author=Sayeed Unisa and Grace Bahalen Mundu |website=paa2011.princeton.edu}}</ref>

====China====
{{See also|Concubinage#China}}
In mainland China, polygamy is illegal under the [[Civil Code of the People's Republic of China|Civil Code]] passed in 2020. This codified a similar 1950 and 1980 prohibition.<ref>{{Cite web|url=http://www.lawinfochina.com/display.aspx?lib=law&id=11|title=Marriage Law of the People's Republic of China|website=www.lawinfochina.com}}</ref>

Polygyny where wives are of equal status had always been illegal in China, and had been considered a crime in some dynasties. In family laws from Tang to Qing Dynasties, the status of a wife, concubines and maid-mistresses could not be altered.<ref>{{cite web|url=https://www.douban.com/note/157772811/|title=毋以妾为妻|work=douban.com|access-date=10 December 2016}}</ref> However, concubinage was supported by law until the end of the [[Qing dynasty|Qing/Ching dynasty]] of the imperial China (1911).{{citation needed|date=May 2012}} In the past, Emperors could and often did have hundreds to thousands of concubines. Rich officials and merchants of the elite also took concubines in addition to legal wives. The first wife was the head or mother wife; other wives were under her headship if the husband was away. Concubines had a lower status than full wives, generally not being seen in public with their husband and not having rights to decisions in the house. Children from concubines were considered inferior to those of the wife and did not receive equal wealth/legacy from their father. However they were considered legitimate, therefore had many more rights to inheritance of status and wealth than illegitimate children conceived outside a marriage.

Polygamy was ''de facto'' widely practiced in the Republic of China from 1911 to 1949, before [[Kuomintang]] was defeated in the Civil War and retreated to Taiwan. [[Zhang Zongchang]], a well-known warlord, notably declared he had three 'unknowns' – unknown number of rifles, unknown amount of money, and unknown number of concubines.<ref>{{cite journal | last1 = Portwood| first1 = Matthew R.| last2 = Dunn| first2 = John P.| title = A Tale of Two Warlords.

[[Chinese people|Chinese]] men in [[Hong Kong]] could practice concubinage by virtue of the [[Qing Code]]. This ended with the passing of the Marriage Reform Ordinance ({{Cite Hong Kong ordinance|178}}) in 1970. Kevin Murphy of the ''[[International Herald Tribune]]'' reported on the cross-border polygamy phenomenon in Hong Kong in 1995.<ref>{{cite web |url=http://www.iht.com/articles/1995/02/07/lunar.php |title= Hong Kong Targets Its Two-Family Men - International Herald Tribune|website=www.iht.com |archive-url=https://web.archive.org/web/20090210131453/http://www.iht.com/articles/1995/02/07/lunar.php |archive-date=February 10, 2009}}</ref> In a research paper of [[Humboldt University of Berlin]] on sexology, Doctor Man-Lun Ng estimated about 300,000 men in China have mistresses.

Period drama and historical novels frequently refer to the former culture of polygamy (usually polygyny). An example is the ''[[Wuxia]]'' novel ''[[The Deer and the Cauldron]]'' by Hong Kong writer [[Jin Yong|Louis Cha]], in which the protagonist [[Wei Xiaobao]] has seven wives (In a later edition of the novel, Princess Jianning was assigned as the wife, while others are concubines).

====Kyrgyzstan====
A proposal to decriminalize polygamy was heard by the Kyrgyz parliament. It was supported by the Justice Minister, the country's ombudsman, and the Muslim Women's organization ''[[Mutakalim]],'' which had gathered 40,000 signatures in favour of polygamy. But, on March 26, 2007, parliament rejected the bill. President [[Kurmanbek Bakiyev]] is known to oppose legalizing polygyny.<ref>[http://www.rferl.org/featuresarticle/2007/3/D46AEFBC-4179-4966-806C-E0D37A9C815C.html "Kyrgyzstan: Debate On Legalized Polygamy Continues"], Radio Liberty, Radio Free Europe</ref><ref>{{cite news|url=http://www.rferl.org/a/1075507.html|title=Kyrgyz Lawmakers Reject Decriminalizing Polygamy|work=rferl.org|date=8 April 2008 |access-date=10 December 2016}}</ref>

==== Yemen ====
Polygyny is legal in Yemen, a majority Muslim nation, which follows Islamic tradition where polygyny is acceptable up to four wives only if the husband treats all wives justly. Seven percent of married women in Yemen are a part of polygamous relationship. Reports conducted in the country have shown that rural regions are more likely to have polygamous relationships than those in cities or coastal areas.<ref>{{cite news |title=Health: Proximate Determinations of Fertility |url=http://www.yementimes.com/99/iss11/health.htm |work=Yemen Times |issue=11: 15–21 March |date=March 1999 |archive-url=https://web.archive.org/web/20090325093659/http://www.yementimes.com/99/iss11/health.htm |archive-date=25 March 2009 |volume=IX |language=en |id=[Credit attributed by the ''Yemen Times'' — "Adopted and abridged from: YEMEN: Demographic and Maternal and Child Health Survey: 1997, November 1998."]}}</ref>

Factual polygamy and sexual relationships with several adult partners are not punishable in accordance with current revisions of [[Criminal Code of Russia]] and [[Code of the Russian Federation on Administrative Offenses]]. But multiple marriage cannot be registered and officially recognised by Russian authorities because [[Family Code of Russia]] (section 14 and others) prohibits registration of marriage if one of person is in another registered marriage in Russia or another country. Polygamy is tolerated in predominantly Muslim republics such as [[Chechnya]], [[Ingushetia]], and [[Dagestan]].<ref>{{cite news|url=http://news.independent.co.uk/europe/article338474.ece |location=London |first=Andrew |last=Osborn |title=War-ravaged Chechnya needs polygamy, says its leader |work=The Independent |date=2006-01-14 |archive-url=https://web.archive.org/web/20060117043122/http://news.independent.co.uk/europe/article338474.ece |archive-date=2006-01-17 }}</ref>

Chechen politician [[Ramzan Kadyrov]] actively advocated for polygynous marriage to gain legal recognition.

Polygyny was legalized and documented in unrecognised [[Chechen Republic of Ichkeria]] but Russian authorities had annulled these polygynous marriages after they regained control over territory of Ichkeria. Later Ramzan Kadyrov, President of the [[Chechen Republic]], has been quoted on radio as saying that the depopulation of [[Chechnya]] by war justifies legalizing polygamy.<ref>[https://pilegesh.blogspot.com/2007/02/i-do-i-do-i-do-i-do-economic-case-for.html "I Do, I Do, I Do, I Do: The Economic Case for Polygamy"], Pilegesh.org blog</ref> Kadyrov has been supported by Nafigallah Ashirov, the Chairman of the Council of Grand [[Mufti]]s of Russia, who has said that polygamy is already widespread among Muslim communities of the country.<ref>{{cite web|url=http://ipsnews.net/news.asp?idnews=32064 |title=Inter Press Service – News and Views from the Global South |work=ipsnews.net |access-date=10 December 2016 |archive-url=https://web.archive.org/web/20120212142650/http://ipsnews.net/news.asp?idnews=32064 |archive-date=12 February 2012 }}</ref>

In Ingushetia in July, 1999 polygyny was officially recognised and allowed by edict of president of Ingushetia [[Ruslan Aushev]] and registration of polygyny marriages had been started allowing men to marry up to four wives as it relates to Muslim tradition. But this edict had been formally suspended soon by edict of [[President of Russia]] [[Boris Yeltsin]]. One year later this edict of Aushev had been cancelled by the Supreme Court of Ingushetia because of contradiction with Family Code of Russia.<ref name="Aushev Lentapedia">{{cite web|url=http://www.lenta.ru/lib/14163106/full.htm |title=Лентапедия.

Although non-Muslim Russian populations have historically practiced monogamy, Russian politician [[Vladimir Zhirinovsky]] offered to legalize polygyny to encourage population growth and correct the [[Russia demographics#Demographic crisis|demographic crisis of Russians]].

====Serbia====
Serbian Law, which in turn is based on the French Civil Code, permits individuals to only be married monogamously. However, the jurisdiction of the civil law exclusively oversees the marriages conducted in civilian ceremonies, and not those conducted in the religious ones. Given that the law does not require couples to register a religious marriage in the registry of civil marriages (whilst in the neighbouring Bosnia, failing to do so can result in a fine), individuals seeking to practice polygamy are not restricted to do so. One of the best known examples was the chief Mufti of the Islamic Community in Serbia, Dr. Muamer Zukorlic, who was simultaneously married to three women.

====United Kingdom====
In the UK, there are believed to be up to 20,000 polygamous marriages in Britain's Muslim community,<ref>http://www.channel4.com/info/press/news/channel-4-documentary-gains-access-to-the-men-with-many-wives "The Men with many wives" by Channel 4</ref> even though bigamy is an offence.<ref>http://www.legislation.gov.uk/ukpga/Vict/24-25/100/crossheading/bigamy/enacted Offences Against the Person Act 1861</ref> All marriages that happen within the United Kingdom must be monogamous and meet the requirements of the relevant legislation to be perceived as legitimately substantial.

==Religion==

=== Buddhism ===
[[Buddhism]] does not regard marriage as a [[sacrament]] – it is a [[secular]] affair, and normally Buddhist monks do not participate in it (though in some sects priests do marry). Hence marriage receives no religious sanction.<ref name="access to insight">{{cite web |url= http://www.accesstoinsight.org/lib/authors/dewaraja/wheel280.html |title= Accesstoinsight.org |access-date= 13 September 2011}}</ref> Forms of marriage, in consequence, vary from country to country.

[[Polygamy in Thailand]] was legally recognized until 1935. [[Myanmar]] outlawed polygyny from 2015. In [[Sri Lanka]], polyandry was legal in the [[Kingdom of Kandy]], but outlawed by British after conquering the kingdom in 1815.<ref name="access to insight"/> When the Buddhist texts were translated into Chinese, the [[concubine]]s of others were added to the list of inappropriate partners. [[Polyandry in Tibet]] was common traditionally, as was polygyny, and having several wives or husbands was never regarded as having sex with inappropriate partners.<ref name="Berzin2010">

The Parabhava [[List of suttas|Sutta]] states that "a man who is not satisfied with one woman and seeks out other women is on the path to decline". Other fragments in the Buddhist scripture seem to treat polygamy unfavorably, leading some authors to conclude that Buddhism generally does not approve of it<ref name=" ethics of Buddhism">[https://books.google.com/books?id=URZNk9noWJEC&pg=PA101 The Ethics of Buddhism], Shundō Tachibana, Routledge, 1992, {{ISBN|978-0-7007-0230-5}}</ref> or alternatively regards it as a tolerated, but subordinate, marital model.<ref name="introduction to Buddhist ethics">[https://books.google.com/books?id=URZNk9noWJEC&pg=PA101 An introduction to Buddhist ethics]: foundations, values, and issues, Brian Peter Harvey, Cambridge University Press, 2000, {{ISBN|978-0-521-55640-8}}</ref>

===Christianity===
{{Main|Polygamy in Christianity}}
Polygamy is not forbidden in the [[Old Testament]]. The [[New Testament]] is largely silent on polygamy, however, some point to Jesus's repetition of the earlier scriptures, noting that a man and a wife "shall become one flesh".{{efn|{{bibleverse||Genesis|2:24|ESV}}, {{bibleverse||Matthew|19:3–6|ESV}}}} However, some look to [[Paul of Tarsus|Paul]]'s writings to the [[First Epistle to the Corinthians|Corinthians]]: "Do you not know that he who is joined to a prostitute becomes one body with her? For, as it is written, 'The two will become one flesh.{{'"}}{{efn|{{bibleverse||1 Corinthians|6:16|ESV}}}} Supporters of polygamy argue this use of the phrase in relation to prostitution in this verse, means "becoming one flesh" refers to a merely physical, rather than spiritual, union, even when it is used about marriage in other verses.{{citation needed|date=August 2023}}

Most Christian theologians argue that in Matthew 19:3–9 and referring to Genesis 2:24,{{efn|{{bibleverse|Genesis|2:24}}}} [[Jesus]] explicitly states a man should have only one wife:
{{Blockquote|Have ye not read, that he which made them at the beginning made them male and female, And said, For this cause shall a man leave father and mother, and shall cleave to his wife: and they twain shall be one flesh?|source=Matthew 19:3–9{{efn|{{bibleverse|Matthew|19:3–9}}}} }}

In the [[New Testament]], scriptures state that polygamy should not be practiced by certain church leaders. [[1 Timothy]] says that certain Church leaders should have but one wife: "A ''bishop'' then must be blameless, the husband of one wife ({{langx|grc-x-koine|mias gunaikos andra||one-woman man}}), vigilant, sober, of good behavior, given to hospitality, apt to teach". Verse 12 has similar advice regarding deacons having only one wife.{{efn|{{bibleverse|1 Timothy|3:2-12}}}} Similar counsel is repeated in the first chapter of the [[Epistle to Titus]].{{efn-lg|The digital [[Nestle-Aland]] lists only one manuscript (p. 46) as source of the verse, while nine other manuscripts have no such verse, cf. [http://nttranscripts.uni-muenster.de/AnaServer?NTtranscripts+0+start.anv University of Münster ''Institute for New Testament Textual Research'': Transcripts]}}

Periodically, Christian reform movements that have aimed at rebuilding Christian doctrine based on the Bible alone (''[[sola scriptura]]'') have at least temporarily accepted polygyny as a Biblical practice. For example, during the [[Protestant Reformation]], in a document referred to simply as {{lang|de|Der Beichtrat}} (or ''The Confessional Advice'' ),<ref>[https://archive.org/details/bub_gb_kqyauQISxFEC <!-- quote=Dr. Martin Luthers Briefe, Sendschreiben. --> Letter to Philip of Hesse], 10 December 1539, [[De Wette]]-Seidemann, 6:238–244</ref> [[Martin Luther]], whose reformation caused a schism in the Western Christian Church leading to the formation of the Lutheran Church, granted the [[Landgrave]] [[Philip I, Landgrave of Hesse|Philip of Hesse]], who, for many years, had been living "constantly in a state of adultery and fornication",<ref name="Michelet1904">{{cite book |url=https://archive.org/details/lifelutherwritt00luthgoog |title=The Life of Luther Written by Himself |date=1904 |page=[https://archive.org/details/lifelutherwritt00luthgoog/page/n271 251] |chapter=Chapter&nbsp;III: 1536–1545 |chapter-url=https://archive.org/stream/lifelutherwritt00luthgoog#page/n271 |editor-last=Michelet |editor-link=Jules Michelet |translator-first=William |translator-last=Hazlitt |translator-link=William Hazlitt |publisher=[[George Bell and Sons]] |location=London |series=Bohn's Standard Library}}</ref> a dispensation to take a second wife.

On the other hand, the Roman Catholic Church criticizes polygyny in the Catechism of the Catholic Church. Under paragraph 2387 of "Other offenses against the dignity of marriage" of the Catechism of the Catholic Church, it states "is not in accord with the moral law". Additionally, paragraph 1645 of "The Goods and Requirements of Conjugal Love" states "The unity of marriage, distinctly recognized by our Lord, is made clear in the equal personal dignity which must be accorded to husband and wife in mutual and unreserved affection. Polygamy is contrary to conjugal love which is undivided and exclusive."<ref>{{Citation |url=https://www.vatican.va/archive/ccc_css/archive/catechism/ccc_toc.htm|title=Catechism of the Catholic Church|publisher=Vatican|access-date=14 November 2019}}</ref> There are small numbers of Roman Catholic theologians that claim polygyny can be an authentic form of marriage in certain regions such as Africa.<ref>Vittorio Messori (1985).

In [[Sub-Saharan Africa]], there has often been a tension between the Western Christian insistence on monogamy and the traditional practice of polygamy. In some instances in recent times there have been moves for accommodation; in other instances, churches have resisted such moves strongly. African Independent Churches have sometimes referred to those parts of the Old Testament that describe polygamy in defending the practice.

===Hinduism===
The [[Hinduism|Hindu]] scriptures acknowledge numerous occasions of polygyny; it was the norm among kings, the nobility and the extremely wealthy. For instance [[Pandu]], the father of the [[Pandava]]s in [[Mahabharata]], had two wives: Kunti and Madri. Similarly, [[Dasharatha|Dashratha]] had three chief wives: Kausalya, Sumitra, and Kaikeyi. Having more than one wife was a social custom that was believed to increase the prestige of a man.<ref>{{Cite book |last=Rao |first=CN Shankar |url=https://books.google.com/books?id=jjscEAAAQBAJ&dq=vivaha+man+woman&pg=PA103 |title=Sociology of Indian Society |date=September 2004 |publisher=S. Chand Publishing |isbn=978-81-219-2403-0 |page=106 |language=en}}</ref> Although many other personalities including [[Rama]] had only one wife, as monogamy was regarded as the morally superior type of marriage, polygyny remained customary and widely acceptable among Hindus until it was legally abolished for Hindus in India by the Hindu Marriage Act of 1955.

=== Islam ===
{{Main|Polygyny in Islam}}
[[File:The old wife and the new one.jpg|thumb|277x277px|''Old wife and a new one'' (1935) by [[Azim Azimzade]]]] 
Under [[Islamic marital jurisprudence]], Muslim men can have up to four wives at a time. [[Polyandry]], the practice of a woman having more than one husband, is not permitted.

Based on verse 30:21 of [[Quran]] the ideal relationship is the comfort that a couple find in each other's embrace:
{{Blockquote|And one of His signs is that He created for you spouses from among yourselves so that you may find comfort in them. And He has placed between you compassion and mercy. Surely in this are signs for people who reflect.|{{qref|30|21|c=y}}}}

Polygyny is allowed in the Quran but if a man fears he cannot deal justly with them he should only marry one. This is based on verse 4:3 of [[Quran]] which says:

{{Blockquote|If you fear you might fail to give orphan women their ˹due˺ rights ˹if you were to marry them˺, then marry other women of your choice—two, three, or four. But if you are afraid you will fail to maintain justice, then ˹content yourselves with˺ one or those ˹bondwomen˺ in your possession. This way you are less likely to commit injustice.|{{qref|4|3|c=y}}}}

There are strict requirements to marrying more than one woman, as the man must treat them equally financially and in terms of support given to each wife, according to Islamic law.<ref name = Lukito>{{cite book|author=Ratno Lukito|title=Legal Pluralism in Indonesia: Bridging the Unbridgeable|page=81|publisher=[[Routledge]]}}</ref>

Muslim women are not allowed to marry more than one husband at once. However, in the case of a [[divorce]] or their husbands' death they can remarry after the completion of [[Iddah]], as divorce is legal in Islamic law. A non-Muslim woman who flees from her non-Muslim husband and accepts [[Islam]] can remarry without divorce from her previous husband, as her marriage with non-Muslim husband is Islamically dissolved on her fleeing. A non-Muslim woman captured during war by Muslims, can also remarry, as her marriage with her non-Muslim husband is Islamically dissolved at capture by Muslim soldiers. This permission is given to such women in verse 4:24 of Quran. The verse also emphasizes transparency, mutual agreement and financial compensation as prerequisites for matrimonial relationship as opposed to prostitution; it says:
{{Blockquote|Also ˹forbidden are˺ married women—except ˹female˺ captives in your possession. This is God's commandment to you. Lawful to you are all beyond these—as long as you seek them with your wealth in a legal marriage, not in fornication. Give those you have consummated marriage with their due dowries. It is permissible to be mutually gracious regarding the set dowry. Surely God is All-Knowing, All-Wise. |{{qref|4|24|c=y}}}}

[[Muhammad]] was monogamously married to [[Khadija bint Khuwaylid|Khadija]], his first wife, for 25 years, until she died. After her death, he married multiple women, mostly widows,<ref>"[http://www.islamweb.net/emainpage/articles/134426/prophet-muhammad-and-polygyny-i Prophet Muhammad and polygyny]", IslamWeb.</ref> for social and political reasons.<ref>Sahar El-Nadi, "[http://www.onislam.net/english/ask-about-islam/ethics-and-values/muslim-character/166258-why-did-the-prophet-have-so-many-wives.html Why Did the Prophet Have So Many Wives?]," OnIslam.net</ref> He had a total of nine wives, but not all at the same time, depending on the sources in his lifetime. The Qur'an does not give preference in marrying more than one wife. One reason cited for polygyny is that it allows a man to give financial protection to multiple women, who might otherwise not have any support (e.g. widows).<ref>{{cite web |url=http://www.islamweb.net/ver2/fatwa/ShowFatwa.php?lang=A&Id=18444&Option=FatwaId |title=IslamWeb |publisher=IslamWeb |date=7 February 2002 |access-date=13 September 2011}}</ref> However, the wife can set a condition, in the [[nikah|marriage contract]], that the husband cannot marry another woman during their marriage.

Usually the wives have little to no contact with each other and lead separate, individual lives in their own houses, and sometimes in different cities, though they all share the same husband.

In most Muslim-majority countries, polygyny is legal with [[Kuwait]] being the only one where no restrictions are imposed on it. The practice is illegal in Muslim-majority [[Turkey]], [[Tunisia]], [[Albania]], [[Kosovo]] and the [[Central Asia]]n countries.<ref>{{cite book|url=https://books.google.com/books?id=XHF8AgAAQBAJ&pg=PT230|title=Women, Islam and Everyday Life: Renegotiating Polygamy in Indonesia|first=Nina|last=Nurmila|date=10 June 2009|publisher=Routledge|access-date=10 December 2016|via=Google Books|isbn=978-1-134-03370-6}}</ref><ref>{{cite news |url=http://www.thinkafricapress.com/?url=http%3A%2F%2Fthinkafricapress.com%2Ftunisia%2Ffuture-state-feminism#2848 |title=Tunisia: Protecting Ben Ali's Feminist Legacy |author=Maike Voorhoeve |work=[[Think Africa Press]] |date=31 January 2013 |access-date=23 January 2015}}</ref><ref>{{cite book |last1=Kudat |first1=Ayșe |last2=Peabody |first2=Stan |last3=Keyder |first3=Çağlar |title=Social Assessment and Agricultural Reform in Central Asia and Turkey |date=3 April 2000 |publisher=The World Bank |isbn=978-0-8213-4678-5 |url=https://books.google.com/books?id=njPYSxcBV-EC&pg=PA272 |language=en |doi=10.1596/0-8213-4678-4|access-date=10 December 2016}}</ref><ref>{{cite press release|url= https://www.un.org/press/fr/2007/FEM1625.doc.htm|title=Les Experts du CEDAW s'Inquiètent de la Persistance de Stéréotypes Sexistes et de la Situation des Minorités en Serbie|publisher=[[United Nations]]|date= May 16, 2007|access-date= February 3, 2016|author1=((Committee on the Elimination of Discrimination Against Women))|author2=((UN Department of Public Information))|id=Economic and Social CouncilFEM/1625|language=fr}}</ref> Kazakhstan is the only country among the [[Central Asia|Central Asian]] states [namely [[Turkmenistan]], [[Tajikistan]], [[Kyrgyzstan]] and [[Uzbekistan]]] to not criminalize polygyny.

===Judaism===
{{Main|Polygamy#Judaism}}

Polygyny is permitted by the Bible with certain restrictions (e.g., {{Bibleverse|Exodus|21:10|HE}}), and numerous Biblical figures are recorded as having multiple wives. In practice, though, the incidence of polygyny among ancient Jews was limited, and likely was largely restricted to the wealthy.<ref>Gene McAfee [http://www.oxfordreference.com/views/ENTRY.html?subview=Main&entry=t120.e0669 "Sex"] {{Webarchive|url=https://web.archive.org/web/20200728085805/http://www.oxfordreference.com/views/ENTRY.html?subview=Main&entry=t120.e0669 |date=28 July 2020 }} The Oxford Companion to the Bible. Bruce M. Metzger and Michael D. Coogan, eds. Oxford University Press 1993. Oxford Reference Online. Oxford University Press. 19 March 2010.</ref>

Since the 11th century, [[Ashkenazi]] Jews have followed [[Gershom ben Judah]]'s ban on polygyny (except in rare circumstances).<ref>[http://www.faqs.org/faqs/judaism/FAQ/04-Observance/section-55.html Frequently asked questions, Judaism and Polygamy].</ref> Some [[Mizrahi Jews|Mizrahi]] (Middle Eastern) Jewish communities (particularly [[Yemenite Jews]] and [[Persian Jews]]) discontinued polygyny more recently, after they immigrated to countries where it was forbidden or illegal. [[Israel]] prohibits polygamy by law,<ref>''Penal Law Amendment (Bigamy) Law'', 5719-1959.{{verify source|date=August 2013}}</ref><ref>{{cite journal|title=The English Law of Bigamy in a Multi-Confessional Society: The Israel Experience|first=P.|last=Shifman|date=1 January 1978|journal=The American Journal of Comparative Law|volume=26|issue=1|pages=79–89|doi=10.2307/839776|jstor=839776}}</ref> and Mizrahi Jews are not permitted to enter into new polygamous marriages in Israel, though existing polygamous marriages may be maintained. Polygamy may still occur in non-European Jewish communities that exist in countries where it is not forbidden, such as Jewish communities in Iran or Morocco.

==In nature==
{{Main|Polygyny in animals}}

In zoology the term ''polygyny'' is used for a pattern of mating in which a male animal has more than one female mate in a breeding season.<ref name="dictionary.com">{{cite web |url=http://dictionary.reference.com/browse/polygyny |title=Polygyny|work=dictionary.com|access-date=22 October 2015}}</ref> Males get their mates by defending the females directly or holding resources that the females want and need. This is known as resource defense polygyny and males of the bee species ''[[Anthidium manicatum]]'' (also known as the European wool carder bee) exhibit this behavior. Males claim patches of floral plants, ward off conspecific males and other resource competitors, and mate with the multiple females who forage in their territories.<ref>{{cite journal |last1=Lampert |first1=Kathrin P. |last2=Pasternak |first2=Vanessa |last3=Brand |first3=Philipp |last4=Tollrian |first4=Ralph |last5=Leese |first5=Florian |last6=Eltz |first6=Thomas |title='Late' male sperm precedence in polyandrous wool-carder bees and the evolution of male resource defence in Hymenoptera |journal=Animal Behaviour |date=April 2014 |volume=90 |pages=211–217 |doi=10.1016/j.anbehav.2014.01.034 |bibcode=2014AnBeh..90..211L |s2cid=53157215 }}</ref> Males of many species attract females to their territory by either gathering in a lek or going out in search of dispersed females.

Polygyny in eusocial insects means that some insects living in colonies have not only one queen, but several queens.<ref name="dictionary.com"/> Solitary species of insects take part in this practice in order to maximize their reproductive success of the widely dispersed females, such as the bee species ''[[Anthidium maculosum]]''.<ref>{{cite journal |last1=Alcock |first1=John |title=Natural Selection and the Mating Systems of Solitary Bees |journal=American Scientist |date=1980 |volume=68 |issue=2 |pages=146–153 |jstor=29773726 |bibcode=1980AmSci..68..146A }}</ref> Insects such as [[Red flour beetle#Polygamy|red flour beetles]] use polygyny to reduce inbreeding depression and thus maximize reproductive success.

There is '''primary polygyny''' (several queens join to found a new colony, but after the hatching of the first workers the queens fight each other until only one queen survives and the colony becomes monogynous) and '''secondary polygyny''' (a well-established colony continues to have several queens).
