Hōjō Tokimune, regent of Japan (born 1251)

Hōjō Tokimune of the Hōjō clan was the eighth shikken of the Kamakura shogunate, known for leading the Japanese forces against the invasion of the Mongols and for spreading Zen Buddhism. He was the second son of Tokiyori, fifth shikken of the Kamakura shogunate. From birth, Tokimune was seen as the successor of tokusō, the head of the Hōjō clan. In 1268 AD, at the age of 18, he became shikken himself. During his lifetime, the seats of power of the Japanese Emperor, Imperial Regent (sesshō), Imperial Chief Advisor (kampaku), and the shōgun had all been completely marginalized by the Hōjō shikken.
