Quick take
  • These communities practice plural marriage, distinct from the mainstream Church of Jesus Christ of Latter-day Saints.
  • Life is often structured by strict religious doctrine, patriarchal leadership, and an emphasis on large families.
  • Members typically live in isolated, self-sufficient communities with limited outside interaction.
  • The practice raises complex legal, ethical, and human rights concerns, particularly for women and children.

Fundamentalist polygamous communities are groups, primarily in the Western United States and Canada, who continue to practice plural marriage, believing it to be a religious commandment. They are distinct from The Church of Jesus Christ of Latter-day Saints (LDS), which officially discontinued polygamy in 1890 and excommunicates members who practice it. These communities often base their beliefs on early Mormon doctrines and scriptures, interpreting them as requiring plural marriage for salvation.

How These Communities Are Structured

Most fundamentalist polygamous communities are highly structured, often centered around a charismatic male leader or "prophet" who interprets scripture and dictates community rules. Authority is typically patriarchal, with men holding primary decision-making power in both religious and family matters. Families are often large, with one man married to multiple women, and children are raised within this framework, often with a strong emphasis on religious instruction and adherence to group norms.

Daily Life and Social Norms

Daily life often emphasizes self-sufficiency, hard work, and limited interaction with the outside world. Many communities operate their own schools, businesses, and social services, fostering a sense of insularity. Women traditionally take on roles focused on homemaking, child-rearing, and supporting their husbands, while men are often involved in leadership, providing for the family, and community maintenance. Social interactions are largely confined to community members, and strict dress codes, moral guidelines, and behavioral expectations are common.

The existence of fundamentalist polygamous communities matters because it brings to light complex intersections of religious freedom, human rights, and the rule of law. Issues such as child marriage, abuse, exploitation, and financial fraud have been documented in some of these groups, leading to legal interventions and public scrutiny. For individuals, particularly women and children, life within these communities can present unique challenges related to autonomy, education, healthcare, and integration into broader society, making the question of when and how to intervene a continuous societal concern.

Are these groups part of the mainstream Mormon church?
No. The Church of Jesus Christ of Latter-day Saints (often called the Mormon church) officially ended the practice of polygamy in 1890 and excommunicates members who practice it. Fundamentalist polygamous groups are separate religious organizations that broke away from the mainstream church over this issue.
Is polygamy legal in the United States or Canada?
No, bigamy (being legally married to more than one person) is illegal in all U.S. states and Canadian provinces. While some fundamentalist groups practice "spiritual" or "plural" marriages not recognized by the state, they can face legal charges if they attempt to legalize multiple marriages.
What are the common challenges faced by individuals in these communities?
Challenges can include limited access to education, healthcare, and outside information, as well as social isolation. For women and children, issues like forced marriage (including child marriage), abuse, and lack of personal autonomy have been reported in some groups, leading to significant human rights concerns.
How do people leave fundamentalist polygamous communities?
Leaving can be extremely difficult due to social isolation, lack of education, limited financial resources, and fear of retribution or losing family connections. Support organizations exist to help individuals transition out, providing resources for housing, education, and emotional support.
Are all fundamentalist polygamous communities the same?
No, there is diversity among these groups. While they share the core belief in plural marriage, they can differ significantly in their specific doctrines, leadership styles, strictness of rules, and degree of isolation from mainstream society.
