尊王攘夷
Shungaku returned to Fukui, and from June 1863, began preparation on a plan to raise an army consisting of all of the samurai of Fukui Domain, which would march on Kyoto and would be led by Matsudaira Mochiaki. Although Satsuma Domain, Kumamoto Domain and Kaga Domain amenable to the idea and there was no immediate opposition from Emperor Kōmei, his appeals to other domains went unanswered and the shogunate was not supportive, so the proposed coup never took place. Instead, there were increasing acts of assassination against members of the Tokugawa clan by pro-"Sonnō jōi" "rōnin".
