1890 Manifesto
The "1890 Manifesto", sometimes simply called "The Manifesto", is a statement which officially disavowed the continuing practice of plural marriage in The Church of Jesus Christ of Latter-day Saints (LDS Church). Issued by church president Wilford Woodruff in September 1890, the Manifesto was a response to mounting anti-polygamy pressure from the United States Congress, which by 1890 had disincorporated the church, escheated its assets to the U.S. federal government, and imprisoned many prominent polygamist Mormons.
The Manifesto was a dramatic turning point in the history of the LDS Church. It officially prohibited church members from entering into any marriage prohibited by the law of the land, and made it possible for Utah to become a U.S. state. Nevertheless, even after the Manifesto the church quietly continued to perform a small number of plural marriages in the United States, Mexico, and Canada, thus necessitating a Second Manifesto during U.S. congressional hearings in 1904. Though neither Manifesto dissolved existing plural marriages, plural marriage in the LDS Church gradually died by attrition during the early 1900s. The Manifesto was canonized in the LDS Church Standard Works as Official Declaration—1 and is considered by mainstream Mormons to have been prompted by divine revelation, which is disputed by Mormon fundamentalists.
