Apocalyptic Marian-influenced Catholic-offshoot movement founded in 1989 in Kanungu, South-Western Uganda. The movement ended on 17 March 2000 with the Kanungu fire and subsequent mass-grave discoveries totalling approximately 778 deaths — one of the deadliest cult-related events on record.

Defunct Canadian apocalyptic Christian-derived communal-living movement led by Roch Thériault from around 1977 until his 1989 arrest in Ontario. Thériault was convicted of second-degree murder of community member Solange Boilard in 1993 and sentenced to life imprisonment. He died in custody in 2011. The case is one of the most extensively documented Canadian high-control-community cases on the public record.

Defunct Mormon-fundamentalist violent splinter founded in 1972 by Ervil Morrell LeBaron after a fratricidal split from the Church of the Firstborn of the Fulness of Times. The movement is one of the most extensively documented violent religious-splinter cases in the US public record, with multiple criminal convictions of Ervil LeBaron, members of the LeBaron family, and adherents for murders carried out under a 'blood atonement' / 'hit list' doctrine across the 1970s, 1980s, and into the 2000s.

Polygamist sect that broke from the LDS Church after the 1890 Manifesto. Under Warren Jeffs (Prophet 2002–present, imprisoned 2011) the FLDS practised forced underage marriages, expulsion of teen 'lost boys', and total community control. Heavily documented in court records and federal raids.

Adventist offshoot led by Vernon Howell (David Koresh) at Mount Carmel near Waco, Texas, where Koresh claimed exclusive sexual access to all female members including minors. The 1993 ATF/FBI siege ended in fire killing 76 inside the compound.

Founded by David 'Moses' Berg in 1968. From 1976 to 1987 practised 'Flirty Fishing' (using sex for evangelism and recruitment) and published 'Mo Letters' explicitly endorsing sexual contact between adults and children. Reorganised as 'The Family International' in 2004.

Russian sect (1772+) that broke from the Khlysty over the requirement of literal self-castration ('the seal of fire', 'the small seal' / 'the great seal'). Founder Kondratii Selivanov claimed to be the resurrected Tsar Peter III and the second Christ. Criminalised throughout the Tsarist period; effectively extinct by mid-20th c.

Polygamist Mormon-fundamentalist breakaway centred in the twin towns of Hildale UT and Colorado City AZ (formerly Short Creek) plus the YFZ Ranch near Eldorado TX. Founded 1929–1935 as a polygamy-continuing breakaway from mainstream LDS Church (which had formally ended plural marriage in 1890). Warren Jeffs assumed leadership 2002 after his father Rulon Jeffs's death; convicted 2011 in Texas of two counts of child sexual assault (life+20). FLDS continues under Jeffs's smuggled-from-prison directives; estimated 6,000–10,000 members remain.

Spindale, North Carolina-based Christian sect led by Jane Whaley. The 2017–18 Associated Press investigation documented corporal punishment of children, forced labour at member-owned businesses, and 'blasting' prayer sessions to expel demons.

Philippines-based restorationist Christian movement founded in 1985 by Apollo Quiboloy, who identifies himself in the organisation's own publications as 'the Appointed Son of God'. Subject of an active US Department of Justice federal indictment including sex-trafficking charges, an FBI Most Wanted listing, a Philippine Senate inquiry, and a September 2024 Philippine criminal arrest. All charges remain pending.
