Polygamy Latter Day SaintsEdit

Polygamy, or plural marriage, is a historical practice most closely associated with the early period of the Latter Day Saint movement. In the 19th century, certain leaders and adherents within the movement taught and lived polygamous marriages as part of their religious commitments. The pattern and scale of these marriages varied by community and era, but the public imagination tied polygamy to the development of frontier Mormon settlements in the American West, especially in what would become Utah. The mainstream church later renounced the practice, and the vast majority of Latter Day Saints today do not participate in or endorse polygamy. Yet the historical episode continues to matter for understanding religious liberty, state-building, and religious identity in the United States.

The practice emerged from a distinctive theological frame in which eternal marriages and family lineages were thought to be essential to salvation and exaltation. Early leaders argued that plural marriage could hasten divine objectives, including the growth of the church and the sealing of families for eternity. In practice, polygamy was organized in networks of households, with public acknowledgment of certain marriages and discreet recognition of others. The social fabric of these communities—business, education, and governance in places like Utah Territory—was deeply influenced by the presence of polygamous households.

The public profile of polygamy rose in the 1840s and 1850s as church leaders asserted the doctrine amid internal controversy and external pressure. Prominent figures such as Brigham Young led communities that implemented polygamy as a visible feature of religious life. At its height, the practice drew sharp attention from the federal government and neighboring states, who viewed it as a challenge to social order and the rule of law. The federal response culminated in a series of legal measures intended to curb plural marriages and to penalize those who practiced or facilitated them; these included acts like the Morrill Anti-Bigamy Act and related legislation, followed by enforcement under the Edmunds Act and the Edmunds–Tucker Act. The legal climate helped drive a reorientation within the movement and a strategic shift by the mainstream church.

The turning point for the LDS Church came with the issuance of the 1890 Manifesto, officially declaring an end to new plural marriages. This Development, often described as the church's movement toward normalizing religious life within the American constitutional order, enabled the church to pursue statehood and broader social integration without the destabilizing pressure of ongoing polygamy. Subsequent clarifications, including the Second Manifesto and policy statements by church leaders, further cemented the prohibition of polygamy within the mainstream church. Those who persisted in plural marriage after the Manifesto faced ecclesiastical discipline, and many communities that had practiced polygamy reorganized around monogamous family structures and traditional church, civic, and economic routines.

A distinct and enduring split emerged between the mainstream church and certain offshoots that claim continuity with an earlier era of plural marriage. The mainstream church today rejects polygamy and instructs members that the practice is not divinely mandated for modern adherents. By contrast, various Mormon fundamentalist movement continued to teach and practice plural marriage based on their readings of early revelations and church teachings. Notable groups include Apostolic United Brethren and the more controversial Fundamentalist Church of Jesus Christ of Latter-Day Saints, among others. These groups have been subjects of law enforcement attention and public scrutiny, particularly regarding governance, education, and the rights of children and women in their communities.

Controversies and debates surrounding polygamy in the Latter Day Saint context are multifaceted and continue to provoke strong reactions. Critics—often focusing on gender equality, consent, and the potential for coercion—argue that polygamy produced power imbalances and restricted options for women and girls. Proponents and defenders—often appealing to religious liberty, historical context, and the autonomy of adult participants—contend that plural marriage reflected a voluntary, faith-based practice in a specific historic moment and that the modern abandonment of polygamy by the mainstream church was a prudent adaptation to contemporary civil norms and legal realities. From a perspective attentive to liberty and social order, the state’s role in regulating intimate relationships is legitimate, but so is recognizing the right of individuals to pursue deeply held religious beliefs within constitutional boundaries. Critics who frame polygamy as an unmitigated invasion of rights are accused by some supporters of conflating historical practice with modern moral judgment, a conflation they deem an overreach that overlooks personal agency, community norms, and the evolution of civil law. In this light, the debates over polygamy touch on broader questions about religious pluralism, the limits of religious exemption, and the balance between tradition and reform.

In the modern era, the landscape for polygamy among Latter Day Saints is dominated by two parallel tracks: the mainstream LDS Church’s rejection of the practice and the continued existence of plural-marriage communities among various Mormon fundamentalist movement. The mainstream church emphasizes adherence to a monogamous, legally recognized marriage model and engages in public dialogue about religious liberty within the framework of U.S. law. By contrast, fundamentalist groups pursue what they see as a restoration of early church practice, often under leaders who claim prophetic authority. These differences shape their respective social arrangements, educational norms, and interactions with state and federal authorities. The result is a complex mosaic in which religious history, legal policy, and cultural attitudes intersect.
