At one time about one-third of the world's population lived under communist governments, most notably in the republics of the Soviet Union. Today communism is the official form of government in only five countries: China, North Korea, Laos, Cuba, and Vietnam. However, none of these meet the true definition of communism. Instead, they can be said to be in a transitional stage between the end of capitalism and the establishment of communism. Such a phase was outlined by Karl Marx, and it came to include the creation of a dictatorship of the proletariat. While all five countries have authoritarian governments, their commitment to abolishing capitalism is debatable.
