 The decline of the Tokugawa Shogunate during the "Bakumatsu" period from 1853 led to lessening discrimination against "tozama daimyō".In November 1864, Matsumae Takahiro, the "tozama daimyō" of the Matsumae clan, was appointed as "rōjū", one of the highest-ranking government posts in the Tokugawa government.
