 In Hungary, the disorganised workers who had proclaimed the Hungarian Soviet Republic were fought and defeated by the royal armies of the Kingdom of Romania and the Kingdom of Yugoslavia as well as the army of the First Republic of Czechoslovakia.These communist forces were soon crushed by anti-communist forces and attempts to create an international communist revolution failed.However, a successful revolution occurred in Asia, when the Mongolian Revolution of 1921 established the Mongolian People's Republic (1924–1992).
