Communism
The color red is a symbol of communism around the world. A red five-pointed star sometimes also stands for communism. The hammer and sickle is a well-known symbol of communism. It was on the flags of many communist countries, like the Soviet Union (see top of article). Some communists also like to use pictures of famous communists from history, such as Marx, Lenin, and Mao Zedong, as symbols of the whole philosophy of communism.
