Polygamy has been practiced by mankind for thousands of years. Many of the ancient Israelites were polygamous, some having hundreds of wives. King Solomon (peace be upon him) is said to have had seven hundred wives and three hundred concubines. David (Dawood) had ninety-nine and Jacob (Ya'kub, peace be upon them both) had four. Advice given by some Jewish wise men state that no man should marry more than four wives. No early society put any restrictions on the number of wives or put any conditions about how they were to be treated. Jesus was not known to have spoken against polygamy. As recently as the seventeenth century, polygamy was practiced and accepted by the Christian Church. The Mormons (Church of Jesus Christ of Latter Day Saints) has allowed and practiced polygamy in the United States.
Monogamy was introduced into Christianity at the time of Paul when many revisions took place in Christianity. This was done in order for the church to conform to the Greco-Roman culture where men were monogamous but owned many slaves who were free for them to use: In other words, unrestricted polygamy. Early Christians invented ideas that women were "full of sin" and man was better off to "never marry."
Since this would be the end of mankind these same people compromised and said "marry only one."
Actually there are three kinds of polygamy practiced in Western societies: -serial polygamy, that is, marriage, divorce, marriage, divorce, and so on any number of times; -a man married to one woman but having and supporting one or more mistresses; -an unmarried man having a number of mistresses. Islam condones but discourages the first and forbids the other two.
But, what about those who never marry...?
And, does polygamy only applies in the context of man and women?
