Go-Fukakusa in the context of "Northern Court"

The Northern Court (北朝, hokuchō), also known as the Ashikaga Pretenders or Northern Pretenders, were a set of six pretenders to the throne of Japan during the Nanboku-chō period from 1336 through 1392. Even though the present Imperial House of Japan is descended from the Northern Court emperors, The Southern Court is considered the legitimate line, with the argument being that it was the Southern court which possessed the Imperial Regalia, which was later handed over to the Northern court, thus making Emperor Go-Komatsu the 100th Emperor of Japan. It was in 1911 that Emperor Meiji passed an edict which made the Southern line the legitimate one. Before this, pre-Meiji scholars considered the Northern line as the legitimate line.

The Northern dynasty is also referred to as the "senior line" or the Jimyōin line (持明院統, Jimyōin-tō); Jimyō-in was a temple and retirement residence of this line's emperors Go-Fukakusa and Fushimi.
