Emperor Go-Daigo

The Kamakura shogunate exiled Go-Daigo to Oki Island after his first attempt to overthrow them failed. He escaped two years later, rallying support from disaffected samurai and monks to renew his rebellion.

Go-Daigo overthrew the Kamakura shogunate and restored direct imperial rule. He issued the Kenmu Code, attempting to reassert imperial authority, but his policies alienated the samurai class, leading to rebellion.

After Ashikaga Takauji turned against him, Go-Daigo fled to Yoshino and established the Southern Court. This created a split in the imperial line, leading to the Nanboku-cho period of rival courts lasting until 1392.
