On May 18, 1980, a confrontation broke out in the city of Gwangju between protesting students of Chonnam National University and the armed forces dispatched by the Martial Law Command. The incident turned into a citywide protest that lasted nine days until May 27 and resulted in the Gwangju massacre. Immediate estimates of the civilian death toll ranged from a few dozen to 2000, with a later full investigation by the civilian government finding nearly 200 deaths and 850 injured. In June 1980, Chun ordered the National Assembly to be dissolved. He subsequently created the National Defense Emergency Policy Committee, and installed himself as a member. On 17 July, he resigned his position of KCIA Director, and then held only the position of committee member. In September 1980, President Choi Kyu-hah was forced to resign from president to give way to the new military leader, Chun Doo-hwan.
