Annexation of Korea (1910)

The formal annexation on 22 August 1910 was the culmination of diplomatic, military, and political processes that transformed the Korean Empire into a colony of the Empire of Japan, following precedents set by the First Sino-Japanese War, the Treaty of Shimonoseki (1895), the Russo-Japanese War, and the Eulsa Treaty (1905). The annexation was enacted through the Japan–Korea Treaty of 1910 and implemented by officials from the Office of the Resident-General (Korea), the Governor-General of Korea, and ministries such as the Ministry of Foreign Affairs (Japan) and the Ministry of Home Affairs (Japan), affecting institutions across Seoul, Pyongyang, and Busan.

Background

By the late 19th century the Joseon dynasty faced pressure from regional powers including the Qing dynasty, the Russian Empire, and the Empire of Japan. The Gabo Reform and the Kabo Reforms signaled internal attempts at modernization alongside external interventions like the Imo Incident and the Assassination of Empress Myeongseong (Queen Min). The Treaty of Ganghwa opened Korean ports to Meiji Japan, while the Treaty of Shimonoseki (1895) and subsequent treaties altered sovereignty and trade, setting a path toward greater Japanese occupation forces and the 1905 protectorate following the Battle of Mukden and the Treaty of Portsmouth.

Japan–Korea relations before 1910

After the Eulsa Treaty (1905), which created the Korea Protectorate, Japan installed figures like Itō Hirobumi as Resident-General and consolidated authority through bureaucratic instruments including the Korean Customs Service and interventions by the Japanese Resident-General's Office. Korean rulers such as Emperor Gojong and later Sunjong of Korea faced diplomatic isolation and coercion exemplified by events like the Gapsin Coup and the Donghak Peasant Revolution. Japanese advisors and military units collaborated with institutions including the Korean Imperial Army and the Korean police to suppress dissent, while treaties such as the Japan–Korea Protocol (1904) expanded Japanese influence over fiscal and legal matters.

Treaty of Annexation and Legal Framework

The Japan–Korea Treaty of 1910 abolished the Korean Empire’s sovereignty and transferred legislative, executive, and judicial powers to the Empire of Japan. Signatories and key figures included members of the Japanese cabinet and Korean officials pressured by envoys from the Resident-General. The treaty drew on precedents from the Convention of Kanagawa in how unequal treaties altered status, and was accompanied by decrees issued by the Imperial Japanese Government and promulgations enforced by the Governor-General of Korea that replaced Korean codes with Japanese law and reorganized property rights as administered by the Ministry of Finance (Japan) and the Privy Council (Japan).

Implementation of Colonial Rule

Administration was centralized under the Governor-General of Korea, headquartered in Gyeongseong (modern Seoul), where officials from the Home Ministry (Japan) and the Ministry of Colonial Affairs—or, after 1919, the Government-General of Korea—directed land surveys, taxation, and infrastructure projects such as railways linking Seoul to Pyongyang and Busan. Policies promoted industrialization through corporations like the South Manchuria Railway Company and agricultural reforms that advantaged Japanese settlers and investors, while institutions such as the Choson Ilbo faced censorship alongside cultural assimilation campaigns involving Shinto shrines and Japanese-language schools modeled on Tokyo Imperial University practices. Economic extraction and labor mobilization connected to projects in Manchuria and the Pacific War era intensified social change.

Korean Response and Resistance

Korean elites, intellectuals, and activists responded with petitions, diplomatic appeals to powers including the United States and the Russian Empire, and organized resistance such as the Righteous Army guerrillas and later the Korean independence movement. The 1919 March 1st Movement—inspired by figures like Yu Gwan-sun and proclaimed in Seoul churches and student groups tied to the Provisional Government of the Republic of Korea in Shanghai—galvanized international attention and led to repression by the Japanese military police and the Kenpeitai. Exile communities in Shanghai, Harbin, and Vladivostok coordinated armed units such as the Korean Liberation Army and diplomatic lobbying at forums influenced by the Fourteen Points.

International Reaction and Aftermath

International response was muted: major powers including the United Kingdom, the United States, and the French Third Republic recognized Japan's control under prevailing interests shaped by the Anglo-Japanese Alliance and the outcomes of the Russo-Japanese War. Legal and scholarly debates about the treaty's validity persisted in circles linked to the League of Nations and international law scholars at institutions like The Hague Academy of International Law, while diasporic activism and wartime geopolitics culminated in Korea's liberation following World War II and the Soviet invasion of Manchuria, leading to the Korean Provisional Government’s legacy and the division along the 38th parallel into zones administered by the United States Army Military Government in Korea and the Soviet Civil Administration, precursors to the Republic of Korea and the Democratic People's Republic of Korea.
