History of Korea (1945–1948)

The period 1945–1948 in Korea covers the collapse of the Empire of Japan's rule after World War II, the division of the peninsula along the 38th parallel under Soviet Union and United States occupation, and the political contest that produced the separate states of the Democratic People's Republic of Korea and the Republic of Korea. This era saw intense interaction among figures and organizations such as Kim Il-sung, Syngman Rhee, the Provisional People’s Committee for North Korea, the Korean Provisional Government, and international actors including the United Nations and the Yalta Conference participants. Competing visions promoted by the Korean Communist Party, the Korean Nationalist Party, the Korean Labor Movement, and the People's Committees unfolded amid social dislocation, land reform campaigns, and political violence.

Background: Japanese Occupation and End of World War II

Korea entered 1945 after decades under the Empire of Japan following the Japan–Korea Treaty of 1910, with resistance led by figures associated with the Korean Provisional Government, activists like Kim Gu, militants such as the Korean Independence Army, and labor organizations including the Cheongjin Workers' Union. The impact of Pacific War campaigns including the Soviet–Japanese War and the Atomic bombings of Hiroshima and Nagasaki precipitated Japan's surrender and the Instrument of Surrender (1945), creating a power vacuum that international actors including the Allied powers, the Soviet Union, and the United States Department of State moved to manage through occupation arrangements discussed at the Moscow Conference (1945) and the Yalta Conference. Returning exile leaders from the Shanghai Provisional Government and veterans of the Northeast Anti-Japanese United Army joined domestic movements such as the People's Committees (Korea), while conservative nationalists and religious figures including leaders tied to the Korean Christian Federation contested postcolonial authority.

Division and Allied Occupation (Soviet North, US South)

Following surrender, the peninsula was divided at the 38th parallel as Soviet forces under commanders linked to the Red Army advanced into the north and United States Army Forces in Korea units occupied the south, creating separate occupation regimes overseen by the Soviet Civil Administration and the United States Army Military Government in Korea. In the north, administrators worked with Korean cadres associated with the Provisional People's Committee for North Korea and emerging leaders such as Kim Il-sung, using institutions like the Korean Workers' Party to consolidate authority; in the south, the United States Department of War and officials such as John R. Hodge engaged with conservative politicians including Syngman Rhee and organizations like the Korean Democratic Party. International negotiation attempts, including proposals by the United Nations Temporary Commission on Korea and discussions at the Moscow Conference (1945), failed to produce unified trusteeship acceptable to all Korean factions, while Cold War tensions between the Soviet Union and the United States hardened the division.

Political Reconstruction and Emergence of Factions

Political reconstruction featured the reconstitution of prewar and exile groups such as the Korean Provisional Government, the rise of leftist organizations like the Korean Communist Party and the Korean Democratic Women's League, and the persistence of rightist formations including the Korean Nationalist Party and the Korean Democratic Party. Mass organizations such as the People's Committees (Korea), the General Council of Korean Trade Unions, and student groups influenced by the Korean Student Movement contested authority with veterans' organizations and religious networks including the Korean Christian Federation and the Korean Catholic Church. Key personalities—Kim Tu-bong, Pak Hon-yong, Cho Man-sik, and Kim Gu—embodied divergent programs tied to land reform proposals, coalition arrangements with Soviet advisers, and appeals to the United Nations and U.S. occupation authorities. Debates over trusteeship advocated by the Moscow Conference (1945) and endorsed by some Korean leaders polarized nationalists, leftists, and conservatives, fueling street politics and organizational fractures.

Elections, Governments, and the Establishment of Separate States

Efforts to create nationwide governance included UN-sponsored moves by the United Nations Temporary Commission on Korea and plans for elections opposed by northern authorities and some southern radicals alike, leading to the May 1948 South Korean general election and the April 1948 North Korean parliamentary election as competing legitimizing processes. The Republic of Korea was proclaimed in August 1948 with Syngman Rhee as president after the convening of the Constituent National Assembly (South Korea), while the Democratic People's Republic of Korea was proclaimed in September 1948 under Kim Il-sung and institutions such as the Supreme People's Assembly (North Korea). International recognition split among states including the Soviet Union and the United States, and legal-political controversies involved actors like the United Nations General Assembly and delegations to the International Committee of the Red Cross and diplomatic missions from the Republic of China.

Social and Economic Conditions (Refugees, Land Reform, Economy)

The immediate postwar environment produced massive displacement involving returnees from the Soviet Union, repatriated forced laborers from Japan, refugees from Manchuria, and internees from camps managed by the United States Army Military Government in Korea. Northern land reform campaigns implemented by the Provisional People's Committee for North Korea and the Korean Workers' Party redistributed land from landlords to peasants, while southern policy debates involved conservative proprietors represented by the Korean Rural Community Movement and peasant activists aligned with the Korean Peasants League. Industrial assets formerly held by the Chaebol precursors and colonial enterprises such as the Chosen Industrial Company faced nationalization pressures in the north and varied restitution and reorganization in the south, amid inflation, food shortages, and labor actions organized by the General Council of Korean Trade Unions and the Korean Confederation of Trade Unions precursors.

Violence, Repression, and Civil Conflict (Yeosu–Suncheon, Bodo League, Labor Unrest)

The period included episodes of violent repression and unrest such as the Yeosu–Suncheon Rebellion, insurgencies tied to the Bodo League massacre, and clashes between security forces like the Korean Constabulary and partisan groups influenced by the Korean People's Army and southern guerrilla formations. State and paramilitary actors, including units under United States Army Military Government in Korea oversight and southern police forces, conducted counterinsurgency operations, while northern security organs associated with the Ministry of State Security (North Korea) pursued purges. Labor unrest manifested in strikes by employees of firms linked to the Chosen Industrial Company and in student protests connected to the April 3 Movement and Gwangju Student Independence Movement legacies, producing cycles of protest, crackdown, and reprisal that shaped the violent transition to separate regimes.
