Patriarch Nikon of Moscow

Nikon, born Nikita Minin was the seventh Patriarch of Moscow and all Rus' of the Russian Orthodox Church, serving officially from 1652 to 1666. He was renowned for his eloquence, energy, piety and close ties to Tsar Alexis of Russia. Nikon introduced many reforms which eventually led to a lasting schism known as Raskol in the Russian Orthodox Church. For many years he was a dominant political figure, often equaling or even overshadowing the Tsar. His liturgical reforms were unpopular among conservatives. In December 1666, Nikon was tried by a synod of church officials, deprived of all his sacerdotal functions, and reduced to the status of a simple monk.
