4·19 혁명
The events of 1960, known as the April Revolution, were touched off by the violent repression of a student demonstration in Masan on the day of the presidential election, March 15. Initially, these protests were quelled by local police, but they broke out again after the body of a student was found floating in the harbor. Subsequently, nonviolent protests spread to Seoul and throughout the country, and Rhee resigned on April 26.
