甲申政変
Korea was ruled by the Japanese Empire from 1910 to 1945. Japan's involvement began with the 1876 Treaty of Ganghwa during the Joseon Dynasty of Korea and increased over the following decades with the Gapsin Coup (1882), the First Sino-Japanese War (1894–95), the assassination of Empress Myeongseong at the hands of Japanese agents in 1895, the establishment of the Korean Empire (1897), the Russo-Japanese War (1904–05), the Taft–Katsura Agreement (1905), culminating with the 1905 Eulsa Treaty, removing Korean autonomous diplomatic rights, and the 1910 Annexation Treaty (both of which were eventually declared null and void by the Treaty on Basic Relations between Japan and the Republic of Korea in 1965).
