The May 16 coup (Hangul: 5.16 군사정변 ; Hanja: 五一六軍事政變 ; RR: "O-illyuk gunsa-jeongbyeon " ) was a military coup d'état in South Korea in 1961, organized and carried out by Park Chung-hee and his allies who formed the Military Revolutionary Committee, nominally led by Army Chief of Staff Chang Do-yong after the latter's acquiescence on the day of the coup.
 The coup rendered powerless the democratically elected government of Yun Bo-seon and ended the Second Republic, installing a reformist military Supreme Council for National Reconstruction effectively led by Park, who took over as Chairman after General Chang's arrest in July.

Korea under Japanese rule began with the end of the short-lived Korean Empire in 1910 and ended at the conclusion of World War II in 1945.
 Japanese rule of Korea was the outcome of a process that began with the Japan–Korea Treaty of 1876, whereby a complex coalition of the Meiji government, military, and business officials sought to integrate Korea both politically and economically into the Empire of Japan.
 A major stepping-stone towards the Japanese occupation of Korea was the Japan–Korea Treaty of 1905, in which the then-Korean Empire was declared a protectorate of Japan.
 The annexation of Korea by Japan was set up in the Japan–Korea Treaty of 1910, which was never actually signed by the Korean Regent, Gojong.

At the conclusion of World War II the Allied nations began the process of disarmament of Axis controlled regions.
 Japan occupied Korea at this time and had been in control since 1910.
 In 1945, the decision was made to have American Marines forces oversee Japanese surrender and disarmament south of the 38th parallel and the Soviet Union would facilitate the change of power to the north.
 At the time there was no political motivation and seemed to be a logical and convenient plan of action.
 The original agreement and intent was to create a unified and independent Korea out of the post Japanese occupation era.
 Instead each side of the 38th parallel established its own government under the influence of the occupational country; the United States in South Korea and the Soviet Union in North Korea.
 Both new Korean governments discredited the other and claimed to be the only legitimate political system.
 Tensions between the North and South escalated and each side began to petition foreign powers for resources and support.
 South Korea wanted weapons and supplies from Truman and the United States government while North Korea sought help from Stalin and the Soviet Union.
 The United States was still war weary from the disruptive World War II campaign and refused South Korea's request for weapons and troops.
 North Korea convinced the Soviet Union to supply them with the weapons and support they requested.
 This decision coincided with the United States withdrawing the last remaining combat troops from South Korea.
 North Korea saw its opportunity and attacked South Korean forces at the 38th parallel on June 25, 1950 and thus initiating the Korean War.
