Polygamy: The state or practice of being married to more than one person at the same time. Some fundamentalist Mormons continue to practice polygamy, known as plural marriage, wherein only men are allowed to marry multiple female partners.
Polygamy was disavowed by the Church of Jesus Christ of Latter-Day Saints in 1890.
