山縣有朋
Historically, the oligarchy that came into power after the Meiji Restoration of 1868 had a strong representation from the Chōshū province, as Itō Hirobumi, Yamagata Aritomo, and Kido Kōin were from there. Other natives famous for their role in the restoration include Yoshida Shōin, Takasugi Shinsaku, and Kusaka Genzui among others.
