Park Chung-hee's 1972 constitution that let him rule indefinitely through a tightly controlled electoral body, backed by emergency decrees.
See it on the Korean History map →What happened
On October 17, 1972, Park declared martial law and dissolved the National Assembly. A new constitution (유신헌법), approved by referendum under martial law, had the president chosen by a National Conference for Unification for unlimited six-year terms, with power to appoint a third of the legislature and rule by emergency decree. Decree No. 9 (1975) banned even criticism of the constitution. 'Yushin,' meaning 'revitalizing reform,' uses the same characters as Japan's Meiji Restoration.
Why it matters
It turned Park's rule into open dictatorship, fueling the opposition that peaked just before his assassination and shaping the democracy movement's demands.
How we know
The constitution text, emergency-decree records, and later retrials and truth commission findings, such as the 2007 acquittal of eight men executed in 1975 in the People's Revolutionary Party case.
Still debated
Whether Park acted mainly out of security fears, as US troops were cut and Washington courted China, or simply to stay in power is debated.

The connection
After narrowly beating Kim Dae-jung in 1971 (about 53% to 45%), and amid US troop cuts and secret talks with the North, Park declared martial law on October 17, 1972, dissolved the National Assembly, and pushed through a constitution that let him rule indefinitely.
When and how
Seoul, October–December 1972; referendum under martial law on November 21; constitution in force December 27.
How we know
Martial-law decrees, referendum results and the constitution text.
Debates and open questions
Whether the 1972 North–South talks were sincere or a pretext: Yushin claimed to prepare for unification, and North Korea adopted a new constitution strengthening Kim Il-sung that same December.
▸Yushin Constitution intensified the struggle for Democratization of South KoreaWell documented
The connection
Yushin turned scattered dissent into a national movement of students, Christian churches, journalists and opposition politicians such as Kim Dae-jung and Kim Young-sam. Emergency decrees jailed hundreds. Kim Young-sam's expulsion from the Assembly in October 1979 sparked the Busan–Masan uprising, days before Park's assassination.
When and how
1972–1979; Busan and Masan, October 16–20, 1979; Park was killed on October 26.
How we know
Court records of emergency-decree cases, many overturned in later retrials, protest records and truth commission reports.
Debates and open questions
Whether the Busan–Masan uprising pushed spy chief Kim Jae-gyu to kill Park; his motives are still debated.
