Most Holy Synod
The Chief Procurator (also Ober-Procurator; обер-прокурор, "ober-prokuror") was the official title of the head of the Most Holy Synod, effectively the lay head of the Russian Orthodox Church, and a member of the Tsar's cabinet. Konstantin Pobedonostsev, a former tutor both of Alexander III and of Nicholas II, was one of the most powerful men to hold the post, from 1880 to 1905.
