Jeju Island refused to start a crackdown on the April 3 incident and tried to stop the sole government of the Republic of Korea.


It is also called the "Yosun Incident," "Yoseun rebellion," "Yosun Ban Incident," "Yosu 14th Regiment," "Yosunbonggi," "Yosun Hangjeon" and "Yosun Gun." It is a tragic event in the history of the nation caused by the confrontation between the left and the right amid the whirlwind of the liberation government along with the Jeju April 3 Incident. In the wake of the incident, the Syngman Rhee government enacted the National Security Law and established a strong anti-communist state. It was often referred to as the "Yeosun and Suncheon Incident" or "Yosu and Suncheon Oct. 19 Incident" since 1995, as residents of the area may be mistaken for being the main object of the rebellion.
