The article is devoted to contacts and interaction between Professor Pérenyi József (1915–1981), the eminent Hungarian specialist in Russian History, and his Soviet colleagues. The evolution of his perception of official Soviet historiography: from fascination after World War II to attempts to overcome the boundaries of the official Soviet narrative in the 1960s and 1970s. are analyzed. In this article the contacts of J.Pérenyi with B.D.Grekov, A.L.Sidorov, M.N.Tikhomirov, T.M.Islamov are studied. The contacts with the A.V.Florovsky, a Russian émigré historian from Prague, were woven into this context.
