A report on Ashikaga Takauji, Nanboku-chō period and Emperor Go-Kōgon

The Nanboku-chō period (南北朝時代, Nanboku-chō jidai, "North and South court period", also known as the Northern and Southern Courts period), spanning from 1336 to 1392, was a period that occurred during the formative years of the Muromachi (Ashikaga) shogunate of Japanese history.During the early period, there existed a Northern Imperial Court, established by Ashikaga Takauji in Kyoto, and a Southern Imperial Court, established by Emperor Go-Daigo in Yoshino.

Emperor Go-Kōgon (後光厳天皇) was the 4th of the Emperors of Northern Court during the Period of the Northern and Southern Courts.

Emperor Kōmyō of the illegitimate Northern Court (see below) was installed as emperor by Takauji in opposition to the exiled Southern Court, beginning the turbulent Northern and Southern Court period (Nanbokuchō), which saw two emperors fight each other and which would last for almost 60 years.

In 1351, Ashikaga Takauji briefly returned to the allegiance of the Southern Dynasty, causing the Southern Court to briefly consolidate control of the Imperial Line.

1354 – Takauji flees with Go-Kōgon; Kitabatake Chikafusa dies.
