The February 28 incident (also called the February 28 massacre, the 228 incident, or the 228 massacre) was an anti-government uprising in Taiwan in 1947 that was violently suppressed by the Kuomintang–led nationalist government of the Republic of China (ROC). Directed by provincial governor Chen Yi and president Chiang Kai-shek, thousands of civilians were killed beginning on February 28. The incident is considered to be one of the most important events in Taiwan's modern history and was a critical impetus for the Taiwan independence movement.
