Matsudaira Katamori
Matsudaira Katamori, after the careful evaluation of the political scene in Kyoto, felt it was needed to change the scope of the Mibu Roshigumi's mission from protecting the Shogunate to patrolling the streets of Kyoto and restoring order in the name of the Tokugawa bakufu. On August 18, 1863, the "Mibu Rōshigumi" was renamed the "Shinsengumi".
