Events of Go-Kōgon's life
In his own lifetime, Go-Kōgon and those around him believed that he occupied the Chrysanthemum Throne from 25 September 1352 to 9 April 1371.
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. However, this peace fell apart in April 1352. On this occasion, the Southern Court abducted Retired (Northern) Emperors Emperor Kōgon and Emperor Kōmyō as well as Emperor Sukō and the Crown Prince Tadahito from Kyoto to Anau, the location of the Southern Court. This produced a state of affairs in which there was no Emperor in Kyoto. Because of this, Imperial Prince Iyahito became emperor in 1352 with the support of Ashikaga Yoshiakira.
During this period, the Era of the Northern and Southern Courts, because of the antagonism between the two competing dynasties, public order in Kyoto was disturbed. The Southern Court repeatedly recaptured Kyoto. Emperor Go-Kōgon was forced to repeatedly flee from Kyoto to Ōmi Province and other places. Around the time that Ashikaga Yoshimitsu was named shōgun (1368), the Southern Courts power weakened, and order was restored to Kyoto. Also around this time, the Emperor's authority began to show its weakness.
On 9 April 1371, he abdicated in favor of his son, who became Emperor Go-En'yū. He continued to rule as Cloistered Emperor until he died of illness on 12 March 1374. He is enshrined with other emperors at the imperial tomb called Fukakusa no kita no misasagi (深草北陵) in Fushimi-ku, Kyoto.
