The Jeju Uprising (followed by the Jeju Massacre) was a rebellion from April 3, 1948 until May 1949 on the South Korean Jeju island that followed the brutal suppression of Korean protesters, some of whom had been marching against the elections that were held only in South Korea (including Jeju Province), by national police employed by the US military government. Between 14,000 and 30,000 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. Several hundred members of the South Korean 11th Constabulary Regiment mutinied; small isolated pockets of fighting continued into September 21, 1954. Up to 40,000 residents of Jeju escaped from the fighting to Japan. Memory of the event was equally brutally suppressed by punishment and destruction of sites. It took nearly 60 years for the Korean government to verbalize an apology in 2006, and, although reparations were promised, none had been made as of 2010.
After Japan's surrender to the Allied forces on 15 August 1945, Korea's 35 years of Japanese occupation ended. Korea was divided at the 38th parallel north, with the Soviet Union assuming trusteeship over the north and the U.S. over the south. Starting in September 1945, Lt. General John R. Hodge established a military government with a temporary Korean administration. In December 1945 the US met with the Soviet Union and United Kingdom to work out joint trusteeship. Due to lack of progress the US approached the United Nations with the "Korean question". On November 14, 1947, the United Nations passed UN Resolution 112, calling for a general election under the supervision of a Temporary UN Commission in May 1948. The Soviet Union refused to comply with the UN resolution and denied the UN Commission access to the northern part of Korea. The USSR first held elections in the north, reporting a 99.6% turnout with 86.3% of voters supporting government backed candidates. The UN Assembly subsequently adopted a new resolution calling for elections in the South Korean part that was still accessible by UN Commission, and which at the time consisted of only the United States Army Military Government in Korea after the Communist People's Party had been banned.
Upset by the partition of the peninsula, the Workers' Party of South Korea planned rallies on March 1 1947 to denounce and block the upcoming general elections scheduled for May 10. United States reports[clarification needed] estimated that some 60,000 or 20% of the Jeju population were party members and a further 80,000 fellow travellers. The arrest of 2,500 party cadres, and the killing of at least three of them, broke up the planned demonstrations.
On March 1, 1947, Jeju people firstly commemorated the Korean struggle against Japanese rule, per the March 1st Movement. Secondly, they tried to denounce the South Korean Constitutional Assembly election scheduled for May 10, 1948. Because Jeju people saw the election as unilateral attempt of the United States military government under the flag of United Nations to separate a southern regime and to employ its first president Syngman Rhee. But police officers from the Korean peninsula fired on the crowd and killed six Jeju people.
On April 3, 1948, the police on Jeju island fired on a demonstration commemorating the Korean struggle against Japanese rule. Outraged, the people of Jeju attacked 12 police stations. In the fighting up to 100 policemen and civilians were killed. Rebels also burned polling centers for the upcoming election and attacked political opponents and their families. They then issued an appeal urging the local population to rise against the American military government.
The South Korean Labour Party and their appeal found sympathy among the local population due to the prevailing sentiment that the local government and police forces had collaborated with the Japanese occupation of Jeju and unrest caused by heavy taxation of agricultural commodities.
The United States Army Military Government in Korea sent three thousand soldiers of the South Korean 11th Constabulary Regiment to reinforce local police, but on April 29 several hundred soldiers mutinied, handing over large small-arms caches to the rebels. The Seoul government also sent several hundred Northwest Youth Association members, a group of anti-communist North Korean refugees as part of a paramilitary force. The Northwest Youth Association were notorious for the killing of male Jeju residents and then forcing the victim's female family members into marriage arrangements with Northwest Youth members so that they would inherit their land.
Lieutenant General Kim Ik Ruhl, commander of the South Korean force on the island, attempted to end the insurrection peacefully by negotiating with the rebels. He met several times with rebel leader Kim Dalsam (South Korean Worker's Party Member cooperating with North Korean Communist Party of Korea and supporter of Kim Il-sung) and his comrades dispatched by Communist Party of Korea but neither side could agree on conditions. The government wanted what amounted to a complete surrender and the rebels demanded disarmament of the local police, dismissal of all governing officials on the island, prohibition of paramilitary youth groups on the island and re-unification of the Korean peninsula. General Kim Ik Ruhl was suddenly recalled to Seoul over his conciliatory approach with the rebels and was surprised when his replacement mounted a sustained offensive against the rebels by the end of the summer.
The guerrillas created base camps in the mountains and the government forces held the coastal towns. Farming communities between the coast and the hills became the primary battle zone. By October 1948, the rebel army consisted of approximately 4,000 combatants, and although many were poorly armed, they scored a number of minor victories over the army. In late fall of 1948 the rebels began openly siding with the North Koreans by flying North Korean flags.
On November 17, 1948, Syngman Rhee regime proclaimed martial law in order to quell the rebellion. One report from December 1948 describes how South Korean soldiers assaulted villages and took away young men and girls. The young men were executed, and girls were also executed after they had been gangraped over two weeks.
At the time of the uprising, the island was controlled by the United States Army Military Government in Korea. Only a small number of Americans were present. Jimmie Leach, then a captain in the U.S. Army, was an adviser to the South Korean Constabulary and claimed that there were six Americans on the island, including himself, and that they could call on two small L-4 scout planes and two old minesweepers converted to coastal cutters, manned by Korean crews. Brutal suppression of the protests by the national police and the army controlled by the U.S. military government under American Colonel James A. Casteel, commander of Jeju's security forces, resulted in thousands of deaths, the destruction of many villages on the island, and more rebellions on the Korean mainland. Rather than dealing with the cause of the issue, sparked by the shooting of civilians by police, the U.S. military dispatched to Jeju was quick to conclude that it was a communist uprising and declared Jeju a "red island". By spring of 1949 four South Korean Army battalions arrived and joined the local constabulary, police forces, and extreme right-wing Northwest Youth Association partisans to brutally suppress protests. The combined forces quickly destroyed or disabled most of the remaining rebel forces. On August 17, 1949, the leadership of the movement fell apart following the killing of major rebel leader Yi Tuk-ku. The U.S. military later called the complete destruction of Jungsangan village - the biggest tragedy of the events - a "successful operation".
The National Committee for the Investigation of the Truth about the Jeju April 3 Incident concluded that the U.S. Army Military Government in Korea and the Korean Military Advisory Group were responsible for the incident as it occurred under the rule of the military government and an American colonel was in charge of the security forces of Jeju. 
The U.S. media documented and publicized the massacre but the U.S. military did not intervene. On May 13, 1949 the American ambassador to South Korea wired Washington that the Jeju rebels and their sympathizers had been, "killed, captured, or converted." Stars and Stripes reported on the South Korean Army’s brutal suppression of the rebellion, local support for the rebels, as well as rebel retaliation against local rightist opponents.
During the Korean War
Immediately after the North Korean attack on South Korea which opened the Korean War, the South Korean military ordered "preemptive apprehension" of suspected leftists nationwide. Thousands were detained on Jeju, then sorted into four groups, labeled A, B, C and D, based on the perceived security risks each posed. On August 30, 1950, a written order by a senior intelligence officer in the South Korean Navy instructed Jeju's police to "execute all those in groups C and D by firing squad no later than September 6." In March 1950, North Korea sent thousands of armed insurgents to resuscitate the guerrilla fighting on Jeju,[dubious ] but by this time the South Korean Army had become particularly adept at counterinsurgency and squashed the new insurgency in only a few weeks.
In one of its first official acts, the South Korean National Assembly passed the National Traitors Act in 1948, which among other measures, outlawed the Workers Party of South Korea. For almost fifty years after the uprising, it was a crime punishable by beatings, torture and a lengthy prison sentence if any South Korean even mentioned the events of the Jeju uprising. The event had been largely ignored by the government. In 1992, President Roh Tae Woo's government sealed up a cave on Mount Halla where the remains of massacre victims had been discovered. After civil rule was reinstated in the 1990s, the government made several apologies for the suppression, and efforts are being made to reassess the scope of the incident and compensate the survivors.
In October 2003, President Roh Moo-hyun apologized to the Jeju people for the brutal suppression of the uprising, stating, “Due to wrongful decisions of the government, many innocent people of Jeju suffered many casualties and destruction of their homes.” Roh had made the first apology as South Korean president for the 1948 massacre. In March 2009, The Truth and Reconciliation Commission confirmed its[who?] findings that "At least 20,000 people jailed for taking part in the popular uprisings in Jeju, Yeosu and Suncheon, or accused of being communists, were massacred in some 20 prisons across the country," when the Korean War broke out.
The commission reported 14,373 victims, 86% at the hands of the security forces and 13.9% at the hands of armed rebels, and estimated that the total death toll was as high as 30,000. Some 70 percent of the island's 230 villages were burned to the ground and over 39,000 houses were destroyed. Of the 400 villages before the uprising only 170 remained afterwards. In 2008, bodies of massacre victims were discovered in a mass grave near Jeju International Airport.
