The Jeju uprising (in South Korea, the Jeju April 3 incident, Korean: 제주 4·3 사건) was an uprising on Jeju Island, South Korea, from April 1948 to May 1949. Tensions on Jeju Island escalated with protests following a police assault incident during the 1947 March 1st Independence Movement Day celebration, and the suppression of those protests which resulted in 6 deaths. A general strike was later organized by the Workers' Party of South Korea (WPSK) from February to March 1948, protesting against the general election scheduled in the United States-occupied half of the peninsula. Kim Dal-sam, the head of the WPSK in Jeju, formed a guerrilla organization to take up arms, and launched an insurgency in April 1948, attacking South Korean police facilities and officers, and right-wing civilians. Following independence in August 1948, the First Republic of Korea (ROK) under President Syngman Rhee escalated the suppression of the uprising on Jeju Island by declaring martial law in November and beginning an "eradication campaign" against insurgents in the rural areas of Jeju in March 1949, defeating them within two months.
