In 1944 the Soviet army entered Yugoslavia. Shulgin was arrested and sentenced to 25 years for his "hostile to communism antisoviet activity". After twelve years in prison he was released in 1956 under the amnesty. Since then he lived in Vladimir. In his later books he argued that communism was no more a disaster for Russia since former Bolsheviks turned into patriots of Russia. In 1965 Shulgin was the main character in a documentary film, "The Verdict of History" in which he told his story to a Soviet historian.
