During the reign of the Soviet Union, there were communist countries throughout Eastern Europe, Asia, and Africa. Communist countries in the twentieth century included Afghanistan, Albania, Angola, Benin, Bulgaria, Cambodia, Congo, Czechoslovakia, East Germany, Ethiopia, Hungary, Mongolia, Mozambique, Poland, Romania, Somalia, South Yemen, Soviet Union, and Yugoslavia. Today, there are only five communist countries in the world.
Mao Zedong took control over China in 1949 and proclaimed China as the People's Republic of China, a communist country. China has remained consistently communist since 1949 although economic reforms have been in place for several years. China has been called "Red China" due to the communist party's control over the country.
A revolution in 1959 led to the taking over of the Cuban government by Fidel Castro. By 1961, Cuba became a fully communist country and developed close ties to the Soviet Union.
Laos, officially the Lao People's Democratic Republic, became a communist country in 1975 following a revolution that was supported by Vietnam and the Soviet Union.
4. North Korea
Korea, which was captured by Japan in World War II, was divided following the war into a Soviet north and American south. Despite being led by the USSR beginning in 1945, North Korea did not become a communist country until 1948.
Vietnam was partitioned at a 1954 conference that followed the First Indochina War. While the partition was supposed to be temporary, North Vietnam became communist and supported by the Soviet Union while South Vietnam was democratic and supported by the United States. Following two decades of war, the two parts of Vietnam were unified and in 1976, Vietnam as a unified country became a communist country.
