. In reality, it was a continuation of Park's military dictatorship, as the government was predominantly members of the Supreme Council, and the National Assembly was dominated by his Democratic Republican Party. Park won re-election in the 1967 presidential election, and the National Assembly passed a constitutional amendment that allowed him to serve a third term, which he narrowly won in the 1971 presidential election against

of the New Democratic Party. Park's popularity began to decline in the early 1970s, and he faced growing domestic opposition from both the public and rival politicians. The 1971 presidential election showed that the New Democratic Party achieved significant electoral gains against the Democratic Republican Party, rising from 32.7% of the vote in 1968 to 44.4%. Public dissatisfaction with Park's authoritarian rule increased as the rapid economic growth of the 1960s began to slow down.

. The legitimacy of Park's government depended on staunch anti-communism, and any moderation of that policy from South Korea's allies threatened the very basis of his rule. In December 1971, Park declared a state of emergency "based on the dangerous realities of the international situation".

Yushin Constitution

The Fourth Republic was governed under the ''Yu-shin Constitution'', also spelled ''Yushin'' (

and began the country's rise into a world power in the late 19th century. The significance of the term ''Yushin'' was the allusion to the "imperial" role which scholars have seen attached to the presidency under the Yusin Constitution, which effectively concentrated all governing power in Park's hands. The Yushin Constitution was a severely authoritarian document, marked by the sweeping executive and legislative powers granted to the president. His term was extended to six years, with no limits on re-election. The president was

through the National Conference for Unification, an electoral college whose delegates were elected by the public. The requirements for presidential candidacy, however, were so stringent that only one candidate could be on the conference's ballot. He was vested with broad powers to suspend constitutional freedoms and rule by decree. Only one concession was given to the National Assembly, the ability to remove the State Council by a vote of no confidence; but even this was a dead letter, as the President could not only dissolve the National Assembly at will, but also had the right to appoint one-third of its members, effectively guaranteeing a
parliamentary majority A majority government is a government by one or more governing parties that hold an absolute majority of seats in a legislature. This is as opposed to a minority government, where the largest party in a legislature only has a plurality of seats. ...
. For all intents and purposes, the Yusin Constitution codified the emergency powers Park had exercised since the previous December, effectively turning his presidency into a legal dictatorship. The new document sparked widespread but ineffective protests. Park argued that Western-style liberal democracy was not suitable for South Korea because of its still-developing economy. Instead, he argued that "Korean-style democracy" with a strong, unchallenged presidency was the only way to keep the country stable. On 21 November 1972, the Yushin Constitution was approved in the
1972 South Korean constitutional referendum A constitutional referendum was held in South Korea on 21 November 1972. President Park Chung-hee had suspended the constitution and dissolved the National Assembly in October. Work began almost immediately on a new constitution. The finished ...

as Park's popularity, and tolerance of his increasingly naked autocracy, declined steadily during the 1970s. The Yushin Constitution allowed Park to legally and more openly violate civil liberties, particularly to suppress his mounting opposition, but this exacerbated resistance to his regime. Park repeatedly promised a transition to full democracy, but few believed him.


Kidnapping of Kim Dae-jung

Kim Dae-jung was involved in a car accident shortly after the 1971 presidential election which left him with a permanent

People's Revolutionary Party Incident

In April 1975, the

All eight were executed only 18 hours after the announcement of the death penalty. Do Ye-jong was one of the original eight people arrested in 1965. The People's Revolutionary Party Incident received attention outside of South Korea and spawned significant negative press for Park's regime. Internally, knowledge about the incident was limited to first-hand experience and information from foreign newspapers shared secretly through universities and churches due to the country's strict censorship laws. Most people viewed the People's Revolutionary Party as a farce for Park to suppress democracy activists rather than communists, and news of the incident spread and emboldened the democratization movement at home and abroad.

In August, Choi resigned and Chun was elected President in the 1980 presidential election by the National Council, running unopposed and winning 99.37% of the vote.
