First Republic of Korea was the government of South Korea from 1948 to 1960, under the inaugural presidency of Syngman Rhee. It was established following the end of the United States Army Military Government in Korea and the first general elections held under United Nations supervision. The republic's tenure was dominated by the Korean War, post-war reconstruction, and increasing authoritarian rule, culminating in its collapse after the April Revolution.

Background and establishment

The republic emerged from the Division of Korea along the 38th parallel north after World War II and the subsequent failure of the Moscow Conference to establish a unified trusteeship. The United Nations Temporary Commission on Korea (UNTCOK) oversaw elections in the south, which were boycotted by Kim Gu and other leaders favoring immediate unification. The Constituent National Assembly was elected in May 1948, drafting the first constitution and proclaiming the republic on 15 August 1948, with Syngman Rhee elected as its first president by the assembly. This act was immediately contested by the establishment of the Democratic People's Republic of Korea under Kim Il Sung in the north.

Political development

The political system, initially a parliamentary system, was quickly amended by Rhee to create a strong presidential system through the first constitutional change in 1952. Facing opposition from figures like Shin Ik-hee and the Democratic Nationalist Party, Rhee's government became increasingly authoritarian. Key events consolidating power included the Bodo League massacre, the passage of the National Security Act, and the controversial 1952 Busan political crisis, where Rhee declared martial law to secure his direct election. The vice presidency was held by individuals such as Yi Si-yeong, Kim Seong-su, and later Jang Myeon. Rhee's ruling party, the Liberal Party, led by Lee Ki-poong, systematically manipulated subsequent elections, including the March 1960 presidential election.

Economic policies and growth

Economic policy was initially focused on stabilization and relief following the Korean War, heavily dependent on United States aid administered through the United Nations Korean Reconstruction Agency (UNKRA). The government prioritized light industry and import substitution, with significant projects like the Pohang Iron and Steel Company begun in the late 1950s. Land reform, the Farmland Reform Act, dismantled the old landlord class but did not lead to major agricultural productivity gains. Economic planning was influenced by figures such as Paik Nak-chun, but growth remained slow and uneven, with corruption scandals like the Sasang-geol incident undermining public confidence. The won underwent significant devaluation during this period.

Foreign relations and the Korean War

The republic's foreign policy was unequivocally pro-Western and anti-communist, centered on the alliance with the United States and recognition by the United Nations. The Korean War began with the invasion by the Korean People's Army in June 1950, leading to the capture of Seoul and the retreat of Republic of Korea Army forces to the Busan Perimeter. The war saw the intervention of United Nations Command forces led by Douglas MacArthur, the Incheon Landing, the advance into North Korea, the counter-intervention by the Chinese People's Volunteer Army, and the eventual stalemate leading to the Korean Armistice Agreement in 1953. Post-war relations were solidified with the Mutual Defense Treaty Between the United States and the Republic of Korea and the normalization of relations with Japan through the 1951 Treaty of San Francisco, though a bilateral normalization treaty with Japan was not concluded until 1965.

Decline and fall

The regime's decline accelerated due to rampant corruption, economic distress, and Rhee's determination to remain in power, exemplified by the passage of the National Security Law to suppress opposition. The direct trigger for its fall was the rigged March 1960 presidential election and the subsequent killing of a student, Kim Ju-yeol, during protests in Masan. This ignited nationwide demonstrations known as the April Revolution, primarily led by students and supported by the opposition Democratic Party. As protests escalated in Seoul, Rhee declared martial law, but the army, under figures like Song Yo-chan, refused to fire on civilians. Facing irreversible pressure from the United States and the public, Syngman Rhee resigned on 26 April 1960 and was swiftly exiled to Hawaii. This led to a brief period of parliamentary rule under Heo Jeong and the establishment of the short-lived Second Republic of Korea.
