Although Nikon's far-flung ambition of steering the country to a theocratic form of government precipitated his defrocking and exile, Tsar Aleksey deemed it reasonable to uphold many of his innovations. During the Schism of the Russian Church, the Old Ritualists were separated from the main body of the Orthodox Church. Archpriest Avvakum Petrov and many other opponents of the church reforms were burned at the stake, either forcibly or voluntarily. Another prominent figure within the Old Ritualists' movement, Boyarynya Morozova, was starved to death in 1675. Others escaped from the government persecutions to Siberia.
