Katsura Tarō
Founded by Prime Minister Katsura Tarō on February 7, 1913, the "Rikken Dōshikai" largely served to support his cabinet against criticism by Ozaki Yukio and his "Rikken Seiyūkai" party, which at the time held a majority of the seats in the Lower House of the Diet of Japan, as well as by Inukai Tsuyoshi of the Rikken Kokuminto party. Katsura was able to convince 90 Diet members (including all 31 members of the Chūō Club and half of the Rikken Kokumintō) to join his new party.
