德川齊昭
Political factions within the "bakufu" clashed over the succession. Tokugawa Nariaki of Mito, Satsuma and others wanted to see Tokugawa Yoshinobu as his successor, while the Ōoku and shogunate officials including Ii Naosuke supported Tokugawa Iemochi, and succeeded. These quarrels ended in the Ansei Purge.
