Gojong, personal name Yi Myeongbok, later Yi Hui, also known as the Gwangmu Emperor, was the penultimate Korean monarch. He ruled Korea for 43 years, from 1864 to 1907, first as the last king of Joseon, and then as the first emperor of the Korean Empire from 1897 until his forced abdication in 1907. His wife, Queen Min, played an active role in politics until her assassination. Gojong oversaw the bulk of the Korean monarchy's final years. He was born into the ruling House of Yi, and was first crowned on 13 December 1863 at the age of twelve. His biological father, Grand Internal Prince Heungseon, acted as regent until he reached the age of majority, although he continued holding power until 1874. At this time, Korea was under policies of strict isolationism. By contrast, Japan had been rapidly modernizing under the Meiji Restoration. In 1876, Japan forcefully opened Korea and began a decades-long process of moving the peninsula into its own sphere of influence. For the following few decades, Korea was highly unstable, and subjected to a number of foreign encroachments. Incidents such as the 1882 Imo Incident, the 1884 Gapsin Coup, the 1894–1895 Donghak Peasant Rebellion, and the 1895 assassination of his wife occurred during his reign. All of these incidents were related to or involved foreign powers. All the while, Gojong attempted to consolidate control, seek foreign support, and modernize the country in order to keep Korea independent. He initiated the Gwangmu Reform, which sought to improve the military, industry, and education, to some amount of success. These reforms were seen as insufficient by some parts of the Korean literati, especially the Independence Club, which Gojong at first tolerated but eventually abolished in 1898. After Japan defeated China in the 1894–1895 First Sino-Japanese War, China lost its suzerainty over Korea, which it had held for centuries. In 1897, shortly after returning from his internal exile in the Russian legation in Seoul, Gojong proclaimed the establishment of the independent Korean Empire, and became its first emperor. Gojong's actions drew the ire of Japan. After Japan defeated Russia in the 1904–1905 Russo-Japanese War, it finally became the sole power in the region, and accelerated its pace of absorbing Korea. Two months after the victory, Korea under Gojong lost diplomatic sovereignty in the Japan–Korea Treaty of 1905, signed by five ministers of Korea. Gojong refused to sign it and made attempts to bring the treaty to the attention of the international community and convince leading powers of the treaty's illegitimacy, but to no avail. Gojong was forced to abdicate by Japan on 20 July 1907, and was replaced by his son, Yi Cheok. He was then confined to Deoksu Palace. He made multiple attempts to escape and establish a government in exile abroad, but was unsuccessful each time. Korea formally became a Japanese colony in 1910, and the Korean imperial family was formally absorbed into the Japanese. Gojong died on 21 January 1919, in his palace, in conditions that were then and are still seen in Korea as suspicious. The official cause of death was cerebral hemorrhage but rumors persisted that Gojong had been poisoned by Japan. His death was a direct catalyst for the March 1st Movement, which in turn bolstered the Korean independence movement.
