List of Latter Day Saint practitioners of plural marriage
According to a consensus of history, many adherents in the early Latter Day Saint movement practiced plural marriage, a doctrine that states that polygyny is ordained of God. Although the largest denomination in the movement, The Church of Jesus Christ of Latter-day Saints, officially abandoned the practice of plural marriage in 1890, a number of churches in the Mormon fundamentalist movement continue to teach and practice it.
