Since 1948, the constitution has undergone five major revisions, each signifying a new republic. The current Sixth Republic began with the last major constitutional revision that took effect in 1988. From its founding until the June Democratic Struggle, the South Korean political system operated under an militaryauthoritarian regime, with the freedom of assembly, association, expression, press and religion as well as civil society activism being tightly restricted. During that period, there were no freely elected national leaders, political opposition is suppressed, dissent was not permitted and civil rights were curtailed.
The head of state is the president, who is elected by direct popular vote for a single five-year[2] term. The president is Commander-in-Chief of the Republic of Korea Armed Forces and enjoys considerable executive powers.
The president appoints the prime minister with approval of the National Assembly, as well as appointing and presiding over the State Council of chief ministers as the head of government. On 12 March 2004, the executive power of then President Roh Moo-hyun was suspended when the Assembly voted to impeach him and Prime Minister Goh Kun became an Acting President. On 14 May 2004, the Constitutional Court overturned the impeachment decision made by the Assembly and Roh was reinstated.
The South Korean judiciary is independent of the other two branches of government, and is composed of two different highest courts. Inferior ordinary courts are under the Supreme Court, whose justices are appointed by the president of South Korea with the consent of the National Assembly. In addition, the Constitutional Court oversees questions of constitutionality, as single and the only court whose justices are appointed by the president of South Korea by equal portion of nomination from the president, the National Assembly, and the Supreme Court Chief justice. South Korea has not accepted compulsory ICJ jurisdiction.
South Korea elects on national level a head of state – the president – and a legislature. The president is elected for a five-year term by the people. The National Assembly (Gukhoe) has 300 members, elected for a four-year term, 253 members in single-seat constituencies and 47 members by proportional representation.
The main two political parties in South Korea are the liberal Democratic Party of Korea (lit. "Together Democratic Party", DPK) and the conservative People Power Party (PPP), formerly the United Future Party (UFP). The liberal camp and the conservative camp are the dominant forces of South Korean politics at present.
South Korea's political history has always been prone to splits from and merges with other parties. One reason is that there is a greater emphasis around the 'politics of the individual' rather than the party; therefore, party loyalty is not strong when disagreements occur. The graph below illustrates the extent of the political volatility within the last 10 years alone. These splits were intensified after the 2016 South Korean political scandal.
This graph traces the recent origins of all six main political parties currently in the Republic of Korea, all of which have either split from or merged with other parties in the last four years. They have emerged from four main ideological camps, from Left to Right: Progressive (socialist), liberal, centrist, and conservative.
In March 2022, Yoon Suk-yeol, the candidate of the conservative opposition People Power Party, won a close election over Democratic Party candidate Lee Jae-myung by the narrowest margin ever. On 10 May 2022, Yoon was sworn in as South Korea's new president.[4]
