The Gwangju Democratization Movement, officially renamed the Gwangju Democratization Movement in 1987, began on May 18, 1980. The citizens of Gwangju, seeking the abolition of martial law and the resignation of General Chun Doo-hwan, initiated the movement. As General Chun Doo-hwan and the military tried to maintain martial law, students and some civilians came together to demonstrate their disapproval. On May 18, 200 male students tried to enter a school that was forced into closure by officials. During the attempt, the students were heavily injured. Seeing this, civilians decided to join in but were stopped by military forces. In the end, many civilians were injured and killed, thus starting the Gwangju Movement. On May 19, as the movement grew to 5000 civilians, the military brought in an armoured motorcar and marched in with guns wielding fixed-bayonets. On May 20, 200,000 civilians marched through the military force and stopped all communications systems in the city so the military would not bring in reinforcements. Thus, Gwangju was freed.
