Polygamy (called plural marriage by Latter-day Saints in the 19th century or the Principle by modern fundamentalist practitioners of polygamy) was practiced by leaders of the Church of Jesus Christ of Latter-day Saints (LDS Church) for more than half of the 19th century, and practiced publicly from 1852 to 1890 by between 20 and 30 percent of Latter-day Saint families. Today, various denominations of fundamentalist Mormonism continue to practice polygamy.
