Postniki
The Postniki were a millennial sect of 19th century Southern Russia, a branch of the Khlysty movement, founded by Abbakum Ivanov Kopylov, a peasant of the Tambov Oblast. Kopylov declared himself the living Christ and gathered a considerable following in the 1820s. After Kopylov's death in 1838, the sect disintegrated in various schisms, giving rise to follow-up groups such as the Staroizrail sect led by Kopylov's disciple Perfil Katasonov.
Soviet scholar A.I. Klibanov still encountered several postniki in Rasskazovo in 1959.
