Enforcement of the 1890 Manifesto caused various splinter groups to leave the LDS Church in order to continue the practice of plural marriage. Polygamy among these groups persists today in Utah and neighboring states as well as in the spin-off colonies. Polygamist churches of Mormon origin are often referred to as "Mormon fundamentalist" even though they are not a part of the LDS Church. Such fundamentalists often use a purported 1886 revelation to John Taylor as the basis for their authority to continue the practice of plural marriage. "The Salt Lake Tribune" stated in 2005 there were as many as 37,000 fundamentalists with less than half of them living in polygamous households.
