Mao Zedong began the Great Proletarian Cultural Revolution (its official name) in 1966. A big part of the program was the closing of China's schools, because Mao saw the majority of educators as bourgeois types who were failing to support the communist revolution. The Cultural Revolution was an insistence on loyalty to communist party ideology.

These radicalized students became militants for Mao over against those whom he considered not revolutionary enough. The Red Guard destroyed historical artifacts and writings of the of China's former culture. They also attacked persons who were seen to be resisting Chairman Mao's permanent revolution.
