Polygamy in North America is often viewed as fringe, but its history is surprisingly deep.
In short: While modern North American law strictly enforces monogamy, plural marriage has a complex, centuries-old history. From indigenous traditions and colonial-era practices to the rise of Mormon fundamentalism, the reality of multiple-partner unions has persisted despite intense legal opposition, social stigma, and the ongoing evolution of state and federal regulations.
Polygamy—the practice of having multiple spouses—has never been a culturally normative institution in North America since European colonization. Historically, indigenous societies, such as the Aztecs, practiced polygyny, where elite members maintained multiple wives based on their economic capacity. However, the 16th-century Laws of Toro imposed by Spanish monarchs established monogamy as the only legitimate marital form, citing religious doctrine to enforce this shift. This Eurocentric view of marriage and property eventually became the standard, marginalizing alternative arrangements.
The most prominent modern association with polygamy in the United States stems from the 19th-century Latter-day Saint movement. Joseph Smith introduced plural marriage in 1843, and the practice was later openly acknowledged by the LDS Church in 1852. Following decades of intense legal conflict with the U.S. government, the church officially abandoned the practice in 1890. Today, the mainstream LDS Church rejects the label of "Mormon" for the splinter groups that continue the tradition. These fundamentalist sects, such as the FLDS, often operate in isolated communities, maintaining their practices despite federal laws like the Edmunds Act and various state-level prohibitions.
Legal enforcement remains a complex challenge. Because many practitioners avoid formal marriage licenses for secondary unions, authorities often struggle to prosecute bigamy directly. Instead, legal interventions frequently focus on related issues like fraud, child abuse, or domestic violence. While the Supreme Court of British Columbia has repeatedly upheld anti-polygamy laws in Canada, and U.S. courts continue to treat bigamy as a crime, public perception is shifting. A 2022 Gallup poll indicated that 23% of Americans now view polygamy as morally acceptable, a significant increase from 7% in 2003, highlighting a growing disconnect between traditional legal frameworks and evolving social attitudes.
