Glossary Timeline

Ryakuō (暦応) was a Japanese era of the Northern Court during the Era of Northern and Southern Courts,^[1] lasting from August 1338 to April 1342.^[2] The emperor in Kyoto was Emperor Kōmyō (光明天皇, Kōmyō-tennō).^[3] Go-Kōgon's Southern Court rival in Yoshino during this time-frame was Emperor Go-Murakami (後村上天皇, Go-Murakami-tennō).

Nanboku-chō overview

The Imperial seats during the Nanboku-chō period were in relatively close proximity, but geographically distinct. They were conventionally identified as:

• Northern capital : Kyoto
• Southern capital : Yoshino.

During the Meiji period, an Imperial decree dated March 3, 1911 established that the legitimate reigning monarchs of this period were the direct descendants of Emperor Go-Daigo through Emperor Go-Murakami, whose Southern Court (南朝, nanchō) had been established in exile in Yoshino, near Nara.^[4]

Until the end of the Edo period, the militarily superior pretender-Emperors supported by the Ashikaga shogunate had been mistakenly incorporated in Imperial chronologies despite the undisputed fact that the Imperial Regalia were not in their possession.^[4]

This illegitimate Northern Court (北朝, hokuchō) had been established in Kyoto by Ashikaga Takauji.^[4]
