Jacksonian era

The Jacksonian era provides a political and cultural frame for the book’s account of early Mormonism. The movement is depicted as both a product of its age’s populist ideals and a reaction against the freedoms and uncertainties associated with them: it elevated the common man while placing unusual authority in a prophet, and it promised spiritual certainty while challenging the legitimacy of surrounding governments.

Populist Beginnings and the Appeal of Order

Joseph Smith’s emerging religion reflected Jacksonian ideals in its challenge to ruling elites and its championing of ordinary people. Yet the book emphasizes a countercurrent within that appeal. Joseph was wary of the competing ideas and democratic instability around him, and Mormonism offered adherents a refuge in hierarchy, discipline, and assurance. Its attraction lay not only in opposition to established authority but also in the prospect of a coherent order amid a society portrayed as increasingly uncertain.

The theology reinforced that sharp division between the faithful and the world beyond them. The Book of Mormon describes humanity through an opposition between the church of God and the church of the devil, while its sacred history locates major events and promises in the Americas. In the book’s account, this distinctly American religious vision gave converts both a chosen identity and a divinely authorized story of their place in the world.

Missouri: Zion and Political Suspicion

The tension became concrete when Joseph directed followers toward Jackson County, where they were to gather and build a New Jerusalem. Mormon arrivals and local residents brought conflicting social and political expectations. Many Mormon immigrants came from northeastern states and favored abolition, while many Missourians had southern roots and owned enslaved people. The book identifies those differences as part of the conflict, but stresses that residents also resented the newcomers’ close-knit community and conviction that divine favor entitled them to claim the region as Zion.

The Saints’ practices made that claim appear politically consequential. They bought land with church funds, preferred to trade among themselves, and voted as a bloc in accordance with Joseph’s direction. As their numbers grew, local residents feared that they would gain control of county government. The book presents the conflict not simply as a clash of beliefs but as a struggle over land, commerce, political influence, and the meaning of legitimate authority.

Joseph’s teaching of free agency sharpened the boundary between those who accepted the religious message and those who rejected it. People could choose, but the choice was framed in absolute moral terms, with little sympathy promised to those who knowingly turned away. In this setting, a revelation directing the Saints to gather in a land described as belonging to their enemies could be read by Missourians as a threat rather than an invitation. The era’s language of popular political participation thus coexisted with a religious community whose own claims and practices intensified fears of collective domination.

Nauvoo and Competing Sovereignties

In Illinois, the same conflict took institutional form. After Joseph Smith escaped confinement in Missouri, he selected a site beside the Mississippi River for a new capital of the Kingdom of God. The settlement grew rapidly: within five years, more than fifteen thousand Saints lived in and around Nauvoo, making it the second-largest municipality in Illinois. A state charter granted the city unusual sovereign rights and powers, in part amid sympathy for the Mormons’ expulsion from Missouri and a desire to attract industrious settlers.

The arrangement gave Joseph substantial authority within a city that the book characterizes as a theocratic principality. His declared religious and political role collided with the expectations of non-Mormon neighbors, who did not want to become subjects of a prophetic ruler. Their alarm was heightened by the Saints’ unified voting and by Joseph’s effort to establish a government of God in place of the elected national government. When he ordered the destruction of the Nauvoo Expositor, opponents saw confirmation of their fear that prophetic authority threatened press freedom and regional stability. The resulting crisis shows how a movement shaped by the era’s challenge to established elites could itself be accused of concentrating power and silencing opposition.

The Conflict Beyond the Era

The book traces the contest between religious claims and civil law into later settings. In Utah, Brigham Young’s position that divine law took precedence over human law accompanied a legal system designed to favor church authority when the two came into conflict. The Utah Territorial Legislature expanded local probate courts, which were controlled by Brigham; Mormon bishops commonly served as judges, and church members made up most juries. This later arrangement was not the same episode as the struggles in Missouri and Nauvoo, but it echoes their central question: whether religious authority could establish its own jurisdiction within, or against, the political order around it.

The Jacksonian frame therefore holds together two impulses rather than resolving them. Mormonism drew strength from a populist challenge to elites and from an American sacred history, yet its pursuit of unity and prophetic order brought it into conflict with pluralism, political competition, and limits on authority. The book uses that contradiction to explain why the movement could regard itself as a defense of the people while its neighbors feared the power it sought to exercise.
