Updated: May 13, 2025

The history of Japanese politics from 1853 to 1868 is the history of the struggle between these two parties, each of which soon changed its name. As the Jo-i party allied itself with the court of Kioto, it became the O-sei or Restoration party. As the Kai-Koku party was associated with the court of Shogun, it became the Bakufu party. The struggle ended in the triumph of the Restoration party.
