A communist state, also known as a Marxist–Leninist state, is a one-party state that is administered and governed by a communist party guided by Marxism–Leninism. Marxism–Leninism was the state ideology of the Soviet Union, the Comintern after Bolshevisation and the communist states within the Comecon, the Eastern Bloc and the Warsaw Pact.[1] Marxism–Leninism remains the ideology of several communist states around the world and the official ideology of the ruling parties of China, Cuba, Laos and Vietnam.[2]
