Korea (1905–1945) Korea between 1905 and 1945 underwent formal loss of sovereignty, colonial incorporation, imperial mobilization, and complex nationalist responses that tied Meiji Japan, Empire of Japan, World War I, World War II, and transnational exile politics to local society. Political figures such as Gojong of Korea, Yi Wan-yong, and activists around the Provisional Government of the Republic of Korea intersected with events including the Russo-Japanese War, the Eulsa Treaty, the March 1st Movement, and the Pacific War. International actors like United States, United Kingdom, Soviet Union, and China influenced postwar outcomes, culminating in division after Japanese surrender and at conferences such as Yalta Conference and Cairo Conference.

Background and Korean Society Before 1905

Late 19th-century Korea featured dynastic institutions under Joseon Dynasty, reforms pursued by figures like Gojong of Korea and factions tied to the Gabo Reform and the Donghak Peasant Revolution, while external pressures from Qing dynasty, Empire of Japan, and Russian Empire reshaped geopolitics. Intellectuals influenced by Silhak, Enlightenment in Korea, and contacts with missionaries from United States and France debated modernization alongside elites in Seoul and reformers such as Kim Ok-gyun and Rhee Syngman. Transport and communication projects linked Korean ports like Incheon and Busan to networks involving Port Arthur and Dalian, while landed elites and tenant farmers confronted social tensions exemplified by uprisings like the Donghak Peasant Revolution.

Protectorate Treaty and Loss of Sovereignty (1905–1910)

Following the Russo-Japanese War, Japan imposed the Eulsa Treaty (Protectorate Treaty) on the Korean Empire, marginalizing sovereignty under figures such as Ito Hirobumi and puppet ministers including Yi Wan-yong. International reactions involved diplomats from United Kingdom, United States, and Russia, while Korean responses ranged from royal protest by Gojong of Korea to diplomatic appeals to Hague Peace Conference, and assassination plots targeting Japanese residents and officials like Ito Hirobumi. The period saw administrative restructuring, land surveys influenced by Nippon Imperialism, and the marginalization of the Korean Empire leading to formal annexation via the Japan–Korea Annexation Treaty.

Colonial Rule Under Japanese Administration (1910–1937)

After the Japan–Korea Annexation Treaty, colonial governance under the Government-General of Korea instituted bureaucrats such as Terauchi Masatake and policies modeled on Imperial Japan precedents affecting taxation, infrastructure, and resource extraction linked to firms like South Manchuria Railway Company. Economic integration connected Korean coal from Taean and iron from Gyeongsang to Japanese industry in Osaka and Tokyo, while legal instruments echoed Meiji Constitution practices. Urbanization in Seoul, industrial hubs in Pyongyang and Busan, and migration patterns involved Koreans, Japanese settlers, and labor recruitment for projects in Manchukuo and the South China Sea.

Mobilization, Cultural Assimilation, and Resistance (1910s–1930s)

Colonial policies promoted assimilation via education reforms, language policies, and Shinto shrine worship connected to State Shinto and administrators from Tokyo Imperial University, provoking cultural resistance from Christians, Confucian scholars, and labor organizers. The March 1st Movement of 1919, inspired by global currents including Wilsonian self-determination and protests in Paris Peace Conference, catalyzed nationalist organizing that included leaders like Yu Gwan-sun and networks reaching the Provisional Government of the Republic of Korea in Shanghai. Labor unrest, peasant movements, and clandestine cells tied to groups such as the Korean National Association, Korean Workers' Party precursors, and anarchist collectives engaged in strikes, uprisings, and intellectual debates reflected by publications linked to Seoul National University precursors and expatriate communities in Vladivostok.

Korea During the Pacific War and Intensified Exploitation (1937–1945)

From the Second Sino-Japanese War and into the Pacific War, Japanese authorities escalated conscription and industrial mobilization drawing Korean men into the Imperial Japanese Army and Korean women into military labor systems labeled by historians as the comfort women system, involving recruitment, coercion, and transportation through ports like Incheon and Dalian. Resources were diverted to arsenals in Kobe and Nagoya, while forced labor sent Koreans to mines in Hokkaido and factories across Manchukuo and Southeast Asia. Cultural suppression intensified with the Sōshi-kaimei name change policy and censorship enforced by the Special Higher Police (Tokkō), prompting clandestine preservation of language and ritual by communities in Jeju and Gyeonggi Province.

Political Movements, Independence Efforts, and Korean Provisional Government

Exiled politicians and activists formed institutions including the Provisional Government of the Republic of Korea in Shanghai with leaders such as Syngman Rhee and Kim Gu, coordinating diplomatic appeals to United States Department of State, liaison with the Chinese Nationalist Party (Kuomintang), and contacts in Soviet Union among Korean communists like Kim Il-sung affiliates in Soviet Far East. Domestic networks included the Korean Liberation Army, secret societies, student groups at institutions influenced by Keijo Imperial University antecedents, and wartime committees that negotiated between collaborationist figures and independence proponents, producing a fragmented but persistent independence movement.

Legacy, Division, and Postwar Consequences (1945)

Japan's defeat and the Japanese surrender in 1945 left Korea liberated but divided along the 38th parallel through choices by United States and Soviet Union occupation authorities, setting the stage for competing administrations in Seoul and Pyongyang and political figures like Syngman Rhee and Kim Il-sung. International agreements at the Cairo Conference and the Potsdam Declaration influenced repatriation, trials related to colonial abuses, and the fate of collaborators such as Yi Wan-yong. The period's legacies include industrial foundations in the north and south, demographic shifts, unresolved grievances over labor mobilization and comfort women, and historiographical debates involving archives from National Archives of Korea, Diplomatic Archives of the Ministry of Foreign Affairs of Japan, and collections in Harvard University and Smithsonian Institution.
