About Tokugawa Yoshinobu
Prince Yoshinobu Tokugawa was a Japanese samurai, daimyo and the 15th and last shōgun of the Tokugawa shogunate of Japan. He was part of a movement which aimed to reform the aging shogunate, but was ultimately unsuccessful. He resigned his position as shogun in late 1867, while aiming at keeping some political influence. After these efforts failed following the defeat at the Battle of Toba–Fushimi in early 1868, he went into retirement, and largely avoided the public eye for the rest of his life. At the instigation of his father, Shichirōmaro was adopted by the Hitotsubashi-Tokugawa family in order to have a better chance of succeeding to the shogunate and changed his first name to Akimune (昭致). However, the opposing faction, led by Ii Naosuke, won out. He became family head in 1847, coming of age that year, receiving court rank and title, and taking the name Yoshinobu. Their candidate, the young Tokugawa Yoshitomi, was chosen, and became the 14th shōgun Iemochi.
