May Fourth Movement (五四运动, 1919)

Student demonstrations at Tiananmen, therefore ironically similar to Tiananmen Square Protests of 1989 (六四事件). Many of the leaders of the Chinese Communist Party (CCP, 中国共产党, 1949-, Cult of Mao/Xi, 毛习邪教, 10.000 year Reich) came from that movement.

In the West, the date is Eclipsed by Star Wars Day however!
