Tokugawa Yoshinobu
During the tenure of the 9th generation lord Matsudaira Katamori, the domain deployed massive amounts of their troops to Kyoto, where Katamori served as Kyoto Shugoshoku. Earning the hatred of the Chōshū domain, and alienating his ally, the Satsuma domain, Katamori retreated with the shōgun Tokugawa Yoshinobu in 1868.
