全斗煥
The years after Park's assassination were marked again by political turmoil, as the previously suppressed opposition leaders all campaigned to run for president in the sudden political void. In 1979, General Chun Doo-hwan led the Coup d'état of December Twelfth. Following the Coup d'état, Chun Doo-hwan planned to rise to power through several measures. On 17 May, Chun Doo-hwan forced the Cabinet to expand martial law to the whole nation, which had previously not applied to the island of Jejudo. The expanded martial law closed universities, banned political activities, and further curtailed the press. Chun's assumption of the presidency through the events of 17 May triggered nationwide protests demanding democracy; these protests were particularly focused in the city of Gwangju, to which Chun sent special forces to violently suppress the Gwangju Democratization Movement.
