The Russian word prokuror also has the meaning of prosecutor.
Chief Procurator (also Ober-Procurator; обер-прокурор, ober-prokuror) was the official title of the head of the Holy Synod, effectively, the lay head of the Russian Orthodox Church and a member of the Tsar's cabinet. Konstantin Pobedonostsev, a former tutor of both Alexander III and Nicholas II, was one of the most powerful men to hold this post.
General Procurator (Procurator General) and Ober-Procurator were major supervisory positions in Russian Governing Senate, with their meaning changing over time. Eventually "Ober-Procurator" became the title of the Chief of a department of the Senate.
