Polygamy in North America

Polygamy is the practice of having more than one spouse at the same time. Specifically, polygyny is the practice of one man taking more than one wife while polyandry is the practice of one woman taking more than one husband. Polygamy is a common marriage pattern in some parts of the world. In North America, polygamy has not been a culturally normative or legally recognized institution since the continent's colonization by Europeans.

Polygamy became a significant social and political issue in the United States in 1852, when the Church of Jesus Christ of Latter-day Saints (LDS Church) made it known that a form of the practice, called plural marriage, was part of its doctrine. Opposition to the practice by the United States government resulted in an intense legal conflict, and culminated in LDS Church president Wilford Woodruff announcing the church's official abandonment of the practice on September 25, 1890.^[1] However, breakaway Mormon fundamentalist groups living mostly in the western United States, Canada, and Mexico still practice plural marriage. In the United States, de facto polygamy is illegal under federal law, under the Edmunds Act, and all states have laws against bigamy.^[2]
