Events of Sukō's life
Sukō occupied the Chrysanthemum Throne from 18 November 1348 until 22 November 1351.
In 1348, he became Crown Prince. In the same year, he became Northern Emperor upon the abdication of Emperor Kōmyō. Although Emperor Kōgon ruled as a cloistered Emperor, the rivalry between Ashikaga Takauji and Ashikaga Tadayoshi began, and in 1351, Takauji returned to the allegiance of the Southern Court, forcing Emperor Sukō to abdicate. This was intended to reunify the Imperial Line.
However, the peace soon fell apart, and in April 1352, the Southern Dynasty evacuated Kyoto, abducting with them Retired (Northern) Emperors Emperor Kōgon and Emperor Kōmyō as well as Emperor Sukō and the Crown Prince Tadahito. Because of this, Takauji made Emperor Kōgon's second son Imperial Prince Iyahito emperor (First Fushimi-no-miya).
Returning to Kyoto in 1357, Emperor Sukō's son Imperial Prince Yoshihito began to work with the Bakufu to be named Crown Prince, but the Bakufu instead decided to make Emperor Go-Kōgon's son (the future Emperor Go-En'yū) Crown Prince instead.
In 1398, Emperor Sukō died. But, 30 years after his death, in 1428, his great-grandson Hikohito (彦仁), as the adopted son of Emperor Shōkō, became Emperor Go-Hanazono, fulfilling Sukō's dearest wish. Sukō is enshrined at the Daikōmyōji no misasagi (大光明寺陵) in Fushimi-ku, Kyoto.
