History of South Korea
The history of South Korea formally begins with its establishment on August 15, 1948.
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.
