Oleg Anatolyevich Platonov (Russian: Оле́г Анато́льевич Плато́нов; born 11 January 1950) is a contemporary Russian writer, historian, and economist. He is the Director General of the Institute for the History of Russian Civilization, a Moscow-based think tank.
He has been described as ultranationalist, anti-Semitic, and a Holocaust denier.
Platonov was born in Yekaterinburg, Russia, then known as Sverdlovsk. In 1972 he graduated from the Moscow College of Consumer Cooperation. Platonov has worked in the international department of TsSU and, since 1977, in the Institute for Labor. In 1995 he organized a research institution Russian Civilization. He lived 7 months in the United States then returned to Russia. Platonov has published the encyclopedic dictionary Holy Rus' and four volumes of the Holy Rus'. The Great Encyclopedia of Russian People (out of a proposed twenty volumes). In that work, he praises the civilization of "Holy Rus'″ which, however, has been undermined since 17th century by various foreign elements ("чужебесия″) - forerunners of 'Jewish-Masonic plotters' that in Platonov's opinion organized the Russian revolution. Though Platonov holds the Bolshevik regime responsible for 87 million lives, he argues Joseph Stalin made "the first step toward the salvation of Russia from Jewish Bolshevism.″
Since 2003, Platonov's encyclopedia publishing center was transformed into the independent think tank 'Institute for the History of Russian Civilization' (short name 'Russian Institute'), whose goal is stated as research and dissemination of the ideas of Metropolitan Ioann of St. Petersburg and Ladoga (Ivan Snychev) (1927–1995) with Platonov as the Institute's Director General.
