Communism is a political and economic ideal and philosophy that was embraced by several Earth nations in the 20th and 21st centuries. The pillar of the Communist philosophy was equality and pre-planned economy. Nations that embraced it included the Soviet Union and China. Slang terms for a person who followed this ideal, better known as a communist, included "pinko", "red" and "commie." It was the clash between communism and capitalism that drove the Earth Cold War.
