His son Alexander III (r. 1881–1894) initiated a period of political counterreform. He strengthened the security police, reorganizing it into an agency known as the Okhrana, gave it extraordinary powers, and placed it under the Ministry of Internal Affairs. Dmitriy Tolstoy, Alexander's minister of internal affairs, instituted the use of land captains, who were noble overseers of districts, and he restricted the power of the zemstvos and the dumas. Alexander III assigned his former tutor, conservative Konstantin Pobedonostsev, to be the procurator of the Holy Synod of the Orthodox Church and Ivan Delyanov to be the minister of education.
