Chapter 21 (Communism)

The modern world found its political and philosophical roots in the 19th century, which was inspired by the teachings of Karl Marx. By the 1970s, most of the world's population lived in societies governed by communism regimes. World War II sparked and extended communism among many countries. In the aftermath of the WWII, many communist parties played various roles in European countries. Revolutionary communist movements began and even threatened to establish governments in the Philippines, Malaysia, Indonesia, Bolivia, Peru, and elsewhere. 

Additionally, during the cold war, the Warsaw Pact brought the Soviet Union and Eastern European communists States together in a military alliance. This alliance was designed to counter the threat from the Western capitalist countries of the NATO alliance. Communism was something that changed many countries and began many revolutions. China and Russia were two countries that upheld revolutions that changed a lot of the first half of the century.
