Ii Naosuke
Mito radicals initiated many of the violent acts which led to the overthrow of the bakufu as well. Starting with the assassination of Ii Naosuke, nationalist terrorism spread in Japan. In Mito, anti-foreign loyalists staged a rebellion, which involved the son of Fujita Toko. The bakufu and domain military forces joined together in order to crush the uprising, and the loyalist movement temporarily lost momentum.
