Coup d'état of May Seventeenth
On October 26, 1979, the former president of South Korea of the time, Park Chung-hee, was assassinated by the leader of the Korean Central Intelligence Agency (KCIA). Following the death of the former president, South Korea entered a state of transition. Times prior to the death of Park Chung-hee, was void of democracy and South Korea was an autocratic state. After the assassination, a revision to change South Korea into a nation of democracy was attempted to be implemented. Choi Kyu-hah, who was the prime minister of the time, became the successor of Park Chung-hee and was appointed the role of acting president. With Choi Kyu-ha in power, restricting regulations of the rule of Park Chung-hee were repealed and opposition leaders and activists, such as Kim Dae-jung, were freed from restraint. Choi Kyu-ha later became the official president of South Korea on December 6, 1979. Despite the attempt to change South Korea from an autocratic state to a democratic nation, the already established ideals stemming from the Yushin Constitution, such as martial law and dictatorial rule, was failed to be abolished and an authoritarian rule of the military remained.
