薩長同盟
During the Boshin War, the domain officially remained a supporter of the shogunate, and contributed many samurai to the "Shōgitai;" however, many of its younger retainers supported the "Sonnō jōi" movement and defected to the Satchō Alliance. After the Battle of Ueno, the final "daimyō" of Sekiyado, Kuze Hironari, submitted to the new Meiji government. He was appointed domain governor under the new administration, until the abolition of the han system in July 1871 and subsequently became a viscount under the "kazoku" peerage. The former Sekiyado Domain was absorbed into the new Chiba Prefecture.
