Why the Mormon Church Abandoned Polygamy and Accepted Federal Authority
How legal pressure, statehood demands, and internal fracture forced the LDS Church to renounce its most controversial practice.
- The LDS Church practiced polygamy as core doctrine until the 1890 Manifesto ended it—driven by federal prosecution, property seizure, and the impossible choice between statehood and faith.
- Reynolds v. United States (1879) established that religious belief alone cannot shield illegal conduct, removing any legal shield polygamists had.
- Church president Wilford Woodruff's reversal was pragmatic survival: Utah needed statehood, the church needed to function, and continued defiance meant ruin.
In 1890, Church president Wilford Woodruff issued the Manifesto—a stunning reversal that declared the LDS Church would no longer practice or authorize polygamy. For decades, plural marriage had been central to Mormon theology and practice. This wasn't a spiritual awakening or doctrinal reinterpretation; it was capitulation to overwhelming federal pressure. The church faced a choice: maintain polygamy and lose everything, or abandon it and survive as an institution.
How Federal Law Boxed In the Church
The 1862 Morrill Anti-Bigamy Act made polygamy a federal crime in U.S. territories, directly targeting Mormon practice in Utah Territory. But the law had teeth only if enforced. For years, conviction was hard—juries were sympathetic, witnesses reluctant, and Utah's Mormon-dominated courts dragged their feet. That changed in 1879 with Reynolds v. United States, a Supreme Court landmark that stripped away the church's main legal defense.
Reynolds established that sincere religious belief is not a legal justification for breaking the law. A man named George Reynolds had argued his polygamy was protected religious practice. The Court disagreed: allowing religious conviction to override civil law would make the believer "a law unto himself" and destroy the rule of law itself. After Reynolds, polygamists had no constitutional shield. Federal prosecutors could now move aggressively.
The church faced escalating consequences. The 1882 Edmunds Act criminalized polygamy further and disqualified polygamists from voting, holding office, or serving on juries—effectively disenfranchising Utah's Mormon leadership. The 1887 Edmunds-Tucker Act went further, allowing the federal government to seize church property and dissolve the church as a legal entity. The LDS Church's vast real estate holdings, temples, and endowments were at risk of confiscation. By 1890, the church's ability to function was in jeopardy.
Statehood as the Pressure Point
Utah's path to statehood became the crucial leverage. Congress would not admit Utah as a state while polygamy remained official church doctrine. Statehood meant representation, economic development, and legitimacy. Without it, Utah remained a federal territory under direct congressional control. By the late 1880s, the pressure was unbearable: the church could either cling to plural marriage and watch its property vanish while Utah remained a dependent territory, or renounce the practice and finally claim statehood.
Woodruff's Manifesto of 1890 was framed as divine guidance, but it was also pure pragmatism. Woodruff announced the church would "cease the practice" of plural marriage and advised members to obey the law. This allowed the church to preserve its core institutions—temples, leadership, property—while abandoning the practice that had defined its identity for forty years. Utah was admitted to the Union in 1896, six years later.
Why This Matters and When It Applied
The abandonment of polygamy reveals how state power ultimately constrains even deeply held religious practice. The LDS Church is a powerful, wealthy institution—yet federal law, property seizure, and the promise of statehood proved stronger than theological conviction. The church didn't change its mind about polygamy's doctrinal truth; it simply stopped practicing it. Many faithful members felt betrayed; some broke away to continue plural marriage in splinter groups that persist today.
This episode also shows the limits of religious freedom in American law. Reynolds v. United States established a principle still applied today: the government can regulate conduct, even religiously motivated conduct, if there is a compelling state interest. The church's surrender wasn't voluntary—it was coerced by law. Yet the outcome normalized the idea that religious minorities must ultimately conform to majoritarian legal standards or face exclusion from full civic participation.
- Woodruff's 1890 Manifesto officially ended the practice, but it did not declare polygamy sinful or theologically false.
- Some church leaders continued to perform plural marriages in secret for years afterward.
- The Second Manifesto (1904) was more explicit in forbidding the practice, signaling that the church's commitment was hardening.
