What is Polygamy?

What is Polygamy?:
Polygamy is any marriage which involves more than two people. Polyandry involves one woman and multiple husbands while polygyny involves one man and multiple wives. Polygamy used to be common in the ancient world and was supported in most religions. Polygamy is obviously endorsed in the Bible, but it’s unclear to what degree it might have been limited to the upper levels of society. Monogamy seems to have become standard by the Roman Era.
