About Hara Takashi
Hara Takashi (原 敬; 15 March 1856 – 4 November 1921), informally known as Hara Kei, was a Japanese politician who served as the Prime Minister of Japan from 1918 until his assassination. Hara was the first commoner and first Christian appointed to be Prime Minister of Japan, and was given the moniker of "commoner prime minister" (平民宰相, heimin saishō). Hara held several minor ambassadorial roles before rising through the ranks of the Rikken Seiyūkai and being elected to the House of Representatives. Hara served as Home Minister in several cabinets under Saionji Kinmochi and Yamamoto Gonnohyōe between 1906 and 1913. Hara was appointed prime minister following the Rice Riots of 1918 and positioned himself as a moderate, participating in the Paris Peace Conference, founding the League of Nations, and relaxing oppressive policies in Japanese Korea. Hara's premiership oversaw the Siberian intervention and the suppression of the March 1st Movement in Japanese-occupied Korea. Hara was assassinated by Nakaoka Kon'ichi, a far-right nationalist, on 4 November 1921. In 1900, Hara returned to politics and joined Itō Hirobumi's newly founded Rikken Seiyūkai, becoming the first secretary-general of the party. Even though it was speculated that Hara became Christian for personal gain at the time, he remained a Christian in public life until the day he died. Based on discussions Hara had with him on his views for the future of Japanese politics during a trip both men took to Korea in 1884, Inoue appointed Hara to become consul-general in Tianjin, and the first secretary to the embassy of Japan in Paris.
