The Yushin Constitution was a political framework established in South Korea in 1972 by President Park Chung-hee. It aimed to strengthen the executive branch and consolidate power, allowing Park to extend his presidency and suppress political opposition. The constitution introduced a system that limited civil liberties and curtailed democratic processes. Under the Yushin system, the president gained significant authority, including the ability to appoint the National Assembly members and control the judiciary. This led to widespread criticism and protests, as many citizens viewed it as a means to maintain authoritarian rule and hinder democratic development in South Korea.
