Terauchi Masatake
In May 1910, the Minister of War of Japan, Terauchi Masatake, was given a mission to finalize Japanese control over Korea after the previous treaties (the Japan–Korea Treaty of 1904 and the Japan–Korea Treaty of 1907) had made Korea a protectorate of Japan and had established Japanese hegemony over Korean domestic politics. On 22 August 1910, Japan effectively annexed Korea with the Japan–Korea Treaty of 1910 signed by Ye Wanyong, Prime Minister of Korea, and Terauchi Masatake, who became the first Japanese Governor-General of Korea.
