The assassination of president Park Chung-Hee on 26 October 1979 by Kim Jae Kyu, terminating his dictatorship, was expected to democratize South Korea soon by people who revived democratization movements.
The National Conference for Unification tried to nominate Choi Kyu Hah as a succeeded president through indirect election. Then some anti-government figures held a fake wedding ceremony - in order to gather people, getting around the law prohibiting any political meeting - to denounce the martial law army and the National Conference for Unification after which the martial law army arrested 140 participants, including 14 persons delivered to the defence security command in Yongsan-gu and tortured. After the large-scale demonstration in Seoul Station, general Chun Doo Hwan, holding de facto real power at that time, declared the emergency martial to escalate and the army assaulted Ewha Womans University where students representatives had gathered and arrested them. The Seoul Spring effectively came to a close with the Gwangju Massacre on 18 May 1980, which spurred future social movements toward Democratization in the country.
