Joseon
Establishment of the Empire and Colonization

The Joseon court, pressured by encroachment from larger powers, felt the need to reinforce national integrity and declared the Korean Empire, along with the Gwangmu Reform in 1897. King Gojong assumed the title of Emperor in order to assert Korea's independence. In addition, other foreign powers were sought for military technology, especially Russia, to fend off the Japanese. Technically, 1897 marks the end of the Joseon period, as the official name of the empire was changed; the Joseon Dynasty still reigned, albeit perturbed by Japan and Russia.

In a complicated series of maneuvers and counter-maneuvers, Japan pushed back the Russian fleet at the Battle of Port Arthur in 1904. With the conclusion of the 1904–1905 Russo-Japanese War with the Treaty of Portsmouth, the way was open for Japan to take control of Korea. After the signing of the Protectorate Treaty in 1905, Korea became a protectorate of Japan. Prince Itō was the first Resident-General of Korea, although he was assassinated by Korean independence activist An Jung-geun in 1909 at the train station at Harbin. In 1910 the Japanese Empire finally annexed Korea.
