The second incident, also known as the "Committee for Re-establishment of the People's Revolutionary Party (PRP) Incident" (in Korean: 인민혁명당 재건위원회 사건) in South Korea, took place on 9 April 1975. In December 1972, the
Park Chung-Hee government launched the "
Yushin-system": an anti-constitutional system in favor of Park's autocracy named after the
Meiji Restoration of Japan. Also, the abduction of
Kim Dae-jung, a leading politician of the opposing party added to the anger of South Korean people caused by the Yushin system. From October 1973, demonstrations against the Park government gained strength. Meanwhile, on 3 April 1974, Park announced the existence of an extreme socialist group: the "People's Revolutionary Party", and prohibited all activities related to the party. ==Revision==
