On February 28, 1947, Chiang Kai-shek's Kuomintang military forces went on a rampage, shooting and killing demonstrators and bystanders in Taipeh, Taiwan (then Formosa). On that day and the days that followed, the KMT killed as many as 10,000 or more Taiwanese under the command of the governor, General Chen Yi.

This massacre was in response to protests of the often corrupt, repressive KMT occupation of Taiwan, which initially had been welcomed after the Japanese occupation. It was the single largest, but not the only such incident, prompting the institution of martial law ten days later. Martial law ended in Taiwan in 1987, but the KMT remained in power until the 2000 presidential election of the Democratic Progressive Party's Chen Shui-bian. The KMT remains a massive, often corrupt political force with vast holdings and ties in the private sector.
