Japan–Korea Annexation Treaty

Japan–Korea Annexing Treaty. The agreement, formally promulgated on August 29, 1910, marked the culmination of Japanese imperialism on the Korean Peninsula following the Russo-Japanese War. It dissolved the Korean Empire and transferred all sovereignty to the Empire of Japan, initiating a period of colonial rule that lasted until the end of World War II. The treaty's legitimacy has been widely contested, with many historians and the modern states of South Korea and North Korea considering it invalid due to the coercive circumstances of its signing.

Background

The path to annexation began with the First Sino-Japanese War, which ended Joseon's traditional suzerainty under the Qing dynasty and increased Japanese influence in Korea. The subsequent Russo-Japanese War solidified Japan's preeminent position, leading to the Japan–Korea Treaty of 1905 (the Eulsa Treaty), which made Korea a protectorate under the Resident-General of Korea. Key figures like Itō Hirobumi, the first Resident-General, and pro-Japanese Korean officials such as Yi Wan-yong worked to undermine Korean sovereignty. Resistance, including the Righteous Army movement and the mission of Homer Hulbert to the Hague Convention of 1907, failed to garner international intervention. The assassination of Itō Hirobumi by An Jung-geun in 1909 hardened Japanese resolve for direct control.

Negotiation and Signing

Following Itō's assassination, the new Resident-General Terauchi Masatake oversaw the final push for annexation. Negotiations were not conducted between equal states but were a series of ultimatums presented to the Korean court. The cabinet of Prime Minister Yi Wan-yong played a central role in acquiescing to Japanese demands. The treaty was signed under duress on August 22, 1910, at the Residency-General in Keijō (modern Seoul), with Yi Wan-yong representing the Korean government and Terauchi Masatake representing Japan. Emperor Sunjong was forced to ratify the document, which was then promulgated by Emperor Meiji on August 29.

Terms and Provisions

The treaty consisted of eight brief articles. Its core provision was the complete and permanent cession of all rights of sovereignty over Korea to the Emperor of Japan. The Korean Emperor and the royal family were to be accorded appropriate dignity and financial provision. The Government-General of Chōsen was established to administer the new territory, with Terauchi Masatake appointed as the first Governor-General. All treaties previously concluded by Korea with other nations, such as those with the United States or the United Kingdom, were declared null and void. The peninsula was officially renamed Chōsen.

Aftermath and Consequences

Immediate consequences included the dissolution of the Korean army and the formal end of the Korean Empire. The Japanese colonial empire implemented a harsh authoritarian rule, suppressing Korean culture and language through policies like the Sōshi-kaimei (name changes). Economic exploitation was rampant, with resources funneled to support Japanese industrialisation and later the Second Sino-Japanese War. Korean resistance continued through events like the March 1st Movement in 1919 and the activities of the Provisional Government of the Republic of Korea in Shanghai. The colonial period shaped modern Korean nationalism and set the stage for the division of Korea after World War II.

Legacy and Controversy

The treaty's legacy remains a profound source of historical contention and diplomatic friction. Both South Korea and North Korea regard it as fundamentally invalid, an illegal act of coercion under international law. This position was formally stated in the 1965 Treaty on Basic Relations. Key controversies include ongoing disputes over issues stemming from the colonial period, such as compensation for comfort women and forced laborers, which were addressed in agreements like the 2015 Japan–South Korea Comfort Women Agreement. The treaty is a central pillar in the historical memory of Japanese war crimes and continues to impact modern relations between Japan, South Korea, and North Korea.
