Konstantin Petrovich Pobedonostsev was a Russian jurist and statesman who served as an adviser to three Russian emperors. During the reign of Alexander III of Russia, Pobedonostsev was considered the chief spokesman for reactionary positions and the éminence grise of imperial politics. Between 1880 and 1905, he served as Over-Procurator of the Most Holy Synod, making him the non-clerical Russian official who supervised the Russian Orthodox Church.
