安芸国
The Mōri clan (毛利氏 "Mōri-shi") was a Japanese samurai clan descended from Ōe no Hiromoto. The family's most illustrious member, Mōri Motonari, greatly expanded the clan's power in Aki Province. During the Edo period his descendants became "daimyō" of the Chōshū Domain under the Tokugawa shogunate. After the Meiji Restoration with the abolition of the "han" system and "daimyō", the Mōri clan became part of the new nobility.
