Gwangju Uprising

The Gwangju Democratization Movement, also known in South Korea as May 18 Democratization Movement (Korean: 오일팔 민주화운동; RR: Oilpal minjuhwaundong; lit. Five One Eight Democratization Movement), was a series of student-led demonstrations that took place in Gwangju, South Korea, in May 1980, against the coup of Chun Doo-hwan. The uprising was violently suppressed by the South Korean military.

Prior to the uprising, at the end of 1979, the coup d'état of May Seventeenth resulted in the installation of Chun Doo-hwan as military dictator and the implementation of martial law. Following his ascent to power, Chun arrested opposition leaders, closed all universities, banned political activities, and suppressed the press.

The uprising began when Chonnam National University students demonstrating against martial law were fired upon, killed, beaten and tortured by the South Korean military. Some Gwangju citizens took up arms and formed militias, raiding local police stations and armories, and were able to take control of large sections of the city before soldiers re-entered the city and suppressed the uprising. While the South Korean government claimed 165 people were killed in the massacre, scholarship on the massacre today estimates 600 to 2,300 victims. Under the military dictatorship of Chun, the South Korean government labelled the uprising as a "riot" and claimed that it was being instigated by "communist sympathizers and rioters" acting under the behest of the North Korean government.

In 1997, 18 May was established as a national day of commemoration for the massacre and a national cemetery for the victims was established. Later investigations confirmed the various atrocities that had been committed by the army. In 2011, the documents of Gwangju Uprising were listed on the UNESCO Memory of the World Register. In contemporary South Korean politics, denial of the Gwangju Massacre is commonly espoused by conservative and far-right groups.
