Cosaques du Don
Most Don Cossacks are Russian Orthodox, who consider themselves guardians of the faith. However, a large percentage of Don Cossacks were Starovers. Even in 1903, a minimum of 150,000 from a total of the 2,500,000 parish members of the Don Eparchy were Starovers. Ataman count Matvei Platov was of a Popovtsy Old Believers Family. Don Cossacks were tolerant of other religions -with the exception of Jews- and accepted Buddhists, Muslims, Old Believers, and pagans into their communities.
