The Jeju Uprising (or the Jeju Massacre) was a communist revolt on Jeju island off the south coast of the Korean Peninsula, beginning on April 3, 1948. Between 14,000 and 60,000 individuals were killed in fighting between various factions on the island or were executed. The brutal suppression of this rebellion by the South Korean army resulted in many deaths, the destruction of many villages on the island, and more rebellions on the Korean mainland. The rebellion, which included the mutiny of several hundred members of the South Korean 11th Constabulary Regiment, lasted until May 1949, although small isolated pockets of fighting continued into September 21, 1954. Up to 40,000 residents of Jeju escaped from the fighting to Japan.Source: Wikipedia, published under the GNU FDL. Retrieved 2014-03-02
