List of ambassadors of the United States to South Korea
At the end of World War II, American forces accepted Imperial Japan's surrender in southern Korea, and Soviet forces accepted the surrender of the Japanese in northern Korea. Talks to agree upon a unity government for Korea failed and in 1948, two separate Korean states were created: the Republic of Korea (South Korea) and the Democratic People's Republic of Korea (North Korea). The United States established diplomatic relations with the new South Korean government, but did not recognize North Korea. Other countries, like the Soviet Union, recognized the Pyongyang government in North Korea, but did not initially establish relations with the South Korean government in Seoul.
April Revolution
The April Revolution, sometimes called the April 19 Revolution or April 19 Movement, was a popular uprising in April 1960, led by labor and student groups, which overthrew the autocratic First Republic of South Korea under Syngman Rhee. It led to the resignation of Rhee and the transition to the Second Republic of South Korea. The events were touched off by the discovery in Masan Harbor of the body of a high school student killed by a tear-gas shell in demonstrations against the elections of March 1960.
