Fonds RU-RGIA/797 - Chancellery of the Chief Procurator (Ober-Prokuror) of the Most Holy Synod

The Procurator (Russian: прокурор, prokuror) was an office initially established in 1722 by Peter the Great, the first Emperor of the Russian Empire, as part of reforms to bring the Russian Orthodox Church more directly under his control.
The Russian word also has the meaning of prosecutor.
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.
The General Procurator (Procurator General) and the Chief Procurator were major supervisory positions in the Russian Governing Senate, which functioned from 1711 to 1917, with their meaning changing over time. Eventually Chief Procurator became the title of the head of a department of the Senate.
