Jimyōin

The Jimyōin line of Japan's imperial house formed the Northern Court in Kyoto during the struggle against the rival Southern Court. The two lines descended from sons of Emperor Go-Saga, whose proposed alternating succession broke down.

In 1336 Ashikaga Takauji seized Kyoto and installed Emperor Kōmyō, while Go-Daigo withdrew to Yoshino. The Ashikaga shoguns supported the northern emperors until the southern claimant surrendered his claim in 1392, bringing the courts together under Go-Komatsu.
