The 1838–1839 expulsion from Missouri was a forced removal that turned an escalating political and religious conflict into a mass flight. After the Haun's Mill Massacre and the encirclement of Far West, the Saints faced demands to surrender their leaders, give up their weapons, pay for property losses, and abandon Missouri. Joseph Smith accepted those terms to avert further immediate danger, but the surrender did not protect the community from plunder and abuse. The expulsion became part of the Saints’ enduring memory of persecution and helped shape their identity as a people whose survival depended on moving together.

Causes and Escalation

The confrontation grew from the rapid arrival of Mormon settlers in Jackson County and their intention to establish a religious community in what they understood as a divinely appointed place. Many newcomers came from northeastern states and favored abolition, while many Missouri residents had southern roots and owned enslaved people. Local suspicion was also fed by the Saints’ communal boundaries and political organization: they purchased land with church funds, favored trading with fellow members, voted as a bloc under Joseph Smith’s direction, and grew numerous enough to appear capable of dominating regional politics.

Religious claims sharpened those tensions. The Saints regarded themselves as God’s chosen people with a divine inheritance in Missouri; some residents interpreted that claim, alongside language dividing the righteous from their enemies, as a threat. Joseph Smith’s teaching that people could choose between the Lord’s side and wickedness left little room for sympathy toward those who rejected the Saints’ religious claims. In 1831, a revelation described Missouri as the Saints’ inheritance and their enemies’ land. To neighbors already alarmed by settlement and political change, such language could sound like an assertion of territorial entitlement rather than a private matter of faith.

By 1838, conflict had become increasingly violent. Joseph Smith was at Far West while ten thousand Missouri troops surrounded the town when the Haun's Mill Massacre took place. Eighteen Saints were killed in and around a blacksmith shop. The massacre, and the prospect of a wider war against a far larger force, altered Joseph’s calculations. Rather than continue an armed confrontation that he believed could end in the destruction of his followers, he sent five Mormon representatives to seek peace from the opposing side.

Surrender and Forced Departure

The Missouri Militia’s terms made clear that peace would come at the cost of the Saints’ home and political independence. They were told to hand over Joseph Smith and six other leaders to face treason charges, compensate Missourians for property that had been plundered or destroyed, surrender their weapons, and leave Missouri altogether. The conditions were severe, but Joseph accepted them, presenting his own surrender as a way to save the lives of the faithful and preserve the church.

On November 1, the Saints surrendered. Joseph, his brother Hyrum Smith, and five other leaders were taken into custody, hastily court-martialed, and found guilty of treason, a capital crime. Missouri’s commanding general ordered Alexander Doniphan to take the prisoners into Far West’s public square and execute them the following morning. Doniphan refused. He argued that the prisoners were American citizens and that a military court could not lawfully condemn civilians to summary execution; he warned that he would hold his superior accountable for murder. His refusal halted the planned execution and spared Joseph’s life at that moment.

That intervention did not undo the other surrender conditions. Disarmed and exposed to hostile residents, the Saints suffered further losses: possessions were plundered, cabins dismantled or burned, livestock killed, and men beaten. Reports of sexual assaults against women and girls added to the community’s fear. The Saints were also given only a few months, until the spring of 1839, to leave the state. The result was not simply the relinquishment of a disputed settlement. It was a coerced departure under conditions in which the community’s property, safety, and continued presence in Missouri had become precarious.

Winter, Imprisonment, and Escape

The winter after the surrender brought famine and severe cold for the Saints as they prepared to leave. Joseph remained imprisoned with nine other Mormon leaders, indicted on charges of treason and murder. From jail he condemned the killings at Haun's Mill, Governor Lilburn Boggs’s extermination order, and the proceedings of the state legislature. His imprisonment gave the expulsion a further political dimension: while the community faced removal, its leading figures remained in the hands of the authorities who had imposed the surrender.

Public opinion shifted as accounts of the Haun's Mill Massacre appeared in Missouri newspapers and calls for an investigation grew. Articles sympathetic to the Mormons circulated, and holding Joseph and the other leaders without trial became an increasing embarrassment to state and local officials. Rather than risk a trial that might end in acquittal, influential people encouraged the sheriff guarding the prisoners to accept an $800 bribe, get drunk, and fall asleep. On April 16, 1839, Joseph and his nine cellmates escaped during the night and traveled cross-country to rejoin the Saints. Most of the community had already completed its exodus and reached Illinois.

Exodus and Historical Significance

The departure was remembered not merely as a change of residence but as a collective ordeal. A later account describes the Saints as leaving in bitterness and hope, their experiences of persecution and loss binding them together. The image of each wagon train as a renewed flight from Egypt captures how the community interpreted migration: leaving Missouri was both an imposed separation from home and a shared passage toward safety. The account also emphasizes that the group’s strength lay in cohesion and practical organization under Brigham Young, who became a capable leader in the migration west.

For Joseph Smith, escape from Missouri was followed by a new beginning in Illinois. About a month after leaving jail, he surveyed a site beside the Mississippi River in Hancock County and decided to build the Saints’ next city there. The expulsion therefore had consequences beyond the loss of their Missouri settlement: it carried the community across a state line and into the founding of Nauvoo. But the memory of forced surrender, imprisonment, and flight remained central to the story the Saints told about themselves, making the Missouri expulsion a defining expression of the conflict between religious claims, local political power, and state authority.
