Popovtsy
Popovtsy are one of the two main branches of the Old Believers, a movement that arose in Russia after the mid-17th-century liturgical reforms of Patriarch Nikon. The term, meaning “priests’ followers,” denotes their acceptance of ordained clergy and episcopal authority, in contrast to the Bespopovtsy, who rejected priestly ordination and hierarchical leadership.
Beliefs and practices: Popovtsy preserve the pre-reform liturgical tradition and sacraments administered by priests and bishops.
History: The split from the official Russian Orthodox Church occurred during Nikon’s reforms in the 1650s–1660s.
Today: Popovtsy remain a major branch of the Old Believers, with several independent groups and jurisdictions
