Yoshinobu Tokugawa (1837-1913), born Keiki Tokugawa, was the last of the shoguns. Before he became shogun in 1866, Japan had opened itself to the outside world. This led to internal conflicts that weakened the shogunate and led many to call for the restoration of the emperor. One of the leaders against the shogunate was Yoshinobu's father, Nariaki Tokugawa. Yoshinobu's forces surrendered to those who supported restoring the emperor in 1868. Yoshinobu was granted the rank of prince in 1902.
