 Various historians and biographers have characterised Lenin's administration as totalitarian, and as a police state, and many have described it as a one-party dictatorship.Several such scholars have described Lenin as a dictator; Ryan stated that he was "not a dictator in the sense that all his recommendations were accepted and implemented", for many of his colleagues disagreed with him on various issues.Fischer noted that while "Lenin was a dictator, [he was] not the kind of dictator Stalin later became", while Volkogonov believed that whereas Lenin established a "dictatorship of the Party", it would only be under Stalin that the Soviet Union became the "dictatorship of one man".
