Since ancient times plural marriage (polis gámos in Greek) has been practiced and in many cultures is still present as something common. The question is, why is their acceptance in some places and their repulsion in others? As in many other "controversial" issues in relationships, this originates in religion.
It is known that Islam is the greatest religion of the common in accepting the polygyny, that is the marriage of a man with multiple wives. It is a myth that is practiced in all Muslim nations. Although in predominantly Arab cultures it is accepted and found just as in Saudi Arabia and the United Arab Emirates, in non-Arab countries or secular Arab countries like Lebanon, Tunisia, Turkey and Malaysia, it is rare if not forbidden. What should be noted is that each of the commonly allowed four wives must have their own house, property and dowry, making this practice almost exclusively for wealthy men.
At present Christianity and Catholicism forbade it, and therefore in countries mostly Latin and others with a history rooted in these religions polygamy is not practiced at all. Due to Mormonism and its presence in the USA, in this country was practiced between this society, although they had several social and legal problems which ended up disappearing among faithful this practice, which is almost only close to the state of Utah.
Between Native American and Mexican indigenous groups this practice is still found, and polygamous sorority, in which several sisters take the same husband, was widespread. In Paraguay, a different phenomenon occurred recently, since after the war in South America a large number of the male population died, the government opted to foment polygyny to restore the population. Here women played an important social role.
In India something very peculiar happens. Hindus ancestrally practiced polygyny, especially among kings. Today the law forbids it for Hindu, although Indian Muslims can do so. Yet the polyandry that allows a woman to have several husbands, a practice less common in the world, is permitted in India to keep the family lands together. The Hunza in northern Pakistan also practice it.
In the "ethnographic atlas" created by George Murdock around 1950, he mentioned that 72% of the 1,770 human societies studied practice polygyny.
