Mormon Church—United States Federal Government

The Mormon Church—United States Federal Government relationship was shaped by a recurring contest over who could govern the Saints: Church leaders, acting on religious authority, or federal institutions asserting national law. It moved from the Church’s pursuit of a largely autonomous community to military confrontation, increasingly forceful legal restrictions, and an official retreat from plural marriage. That retreat did not resolve the conflict so much as change its form; plural marriage continued secretly, while some Saints rejected the Church’s accommodation and treated it as a betrayal of religious principle.

Autonomy and the expanding republic

The Church’s ambition to establish a religiously governed community preceded its western settlement. In Nauvoo, Illinois, a charter granted in 1840 gave the city unusually broad sovereign powers. Joseph Smith stood at the head of this theocratic principality, commanded the Nauvoo Legion, and sought still greater military authority. The charter was a state-level grant, not a federal one, but it established a pattern that would persist in the West: Church leaders sought room to govern their people according to religious authority, while the reach of the United States increasingly constrained that project.

After the Saints left Nauvoo, Church leaders concealed their practice of plural marriage from the wider public. The United States’ expansion westward made that concealment more consequential. The Saints had moved beyond the Mississippi River hoping to escape conflict, but the territory they settled was annexed to the United States after the war with Mexico. Brigham Young then declared the Saints’ allegiance to the republic and petitioned Washington for statehood, which he viewed as a means of preserving some sovereignty. Instead, Congress established Utah Territory on September 9, 1850, and appointed Young governor. Territorial status left federal authority over the region intact and made the boundaries of local religious self-government a continuing point of dispute.

Religious law, territorial power, and war

The clash was especially sharp over plural marriage. Young publicly acknowledged that he had many wives in 1851, then presented the doctrine to a wider Church assembly in Salt Lake City in 1852. He argued that the practice belonged to the Saints’ religious life and should not be dictated by outsiders. More broadly, Church leaders treated divine law as superior to laws they considered contrary to religious obligation. This position was reinforced by a local legal structure: the Utah Territorial Legislature expanded the jurisdiction of probate courts controlled by Young, while Mormon bishops and Church members predominated among judges and juries. The resulting system placed important legal decisions under local institutions closely tied to Church authority, even though Utah remained a territory under federal jurisdiction.

The dispute intensified in 1857. The Utah Territorial Legislature announced that the Saints would refuse federal statutes they deemed unjust and remove federal officers who failed to meet the Church’s standards. President James Buchanan responded by sending officials to restore federal rule and ordering 2,500 armed soldiers to escort them into Salt Lake City and subdue the Saints if necessary. This confrontation, known as the Utah War, threatened armed conflict but ended through negotiation before federal troops and the Saints exchanged a shot. Its resolution left the underlying contest unresolved: federal authority had been asserted, while the Church’s resistance and claims to local rule remained sources of national concern.

Prosecution and resistance

After the Utah War, pressure increasingly took the form of legislation and prosecution. Federal officials and critics regarded the territory’s religious government as a challenge to national authority. Under President Rutherford B. Hayes, the federal government pressed Congress to restrict the political rights of people who practiced or supported plural marriage. The Edmunds Act of 1882 made unlawful cohabitation prosecutable as well as plural marriage, enabling prosecutions that did not require the same proof of a marriage. Federal agents pursued cases across Utah, and roughly a thousand Saints had been jailed by the late 1880s. Some Church members treated imprisonment as evidence of fidelity rather than a reason to comply.

Church leaders responded to the enforcement campaign by establishing settlements beyond the territory where plural marriage could be practiced with less risk of arrest. In 1885, a warrant for John Taylor’s arrest drove the Church president into hiding. Congress escalated its campaign with the Edmunds-Tucker Act in 1887. After Taylor’s death that year, federal lawyers began legal proceedings intended to bankrupt the Church; in 1890 the United States Supreme Court allowed Church holdings to be seized by the government. The sequence joined restrictions on individuals to pressure on the Church as an institution, leaving its leaders to confront the possibility that continued defiance could cost the organization its property and its ability to operate.

The Manifesto and an unresolved settlement

Wilford Woodruff, who became Church president after Taylor, concluded that the Church could no longer sustain its existing position. After reporting that he had struggled over the matter in prayer, he told senior Church leaders that he believed God required the Church to relinquish its practice of plural marriage. On October 6, 1890, he formalized his decision in the Manifesto, declaring an intention to submit to congressional law and advising Latter-day Saints not to contract marriages prohibited by law. The announcement marked a decisive institutional concession to federal authority: rather than maintain official support for plural marriage in defiance of the government, the Church would publicly tell its members to refrain from it.

The settlement was incomplete. The Manifesto did not immediately end plural marriage; for the following two decades, senior Church leaders privately advised that it continue discreetly, and Church leaders secretly performed plural marriages. When the practice became public, the resulting criticism came from outside the Church and from prominent Mormons who wanted the Manifesto enforced. By the 1920s, most Saints and their leaders had turned against plural marriage and supported prosecution of those who continued it. Yet some committed pluralists maintained that the Manifesto suspended rather than revoked Joseph Smith’s revelation on plural marriage. The relationship therefore did not close with one declaration: federal law and official Church policy moved toward compliance, while dissenters preserved an opposing claim of religious obligation beyond the Church’s public position.
