After the death of Takauji, the bakufu (Japanese feudal government headed by shogun), i.e., the Kamakura government officially took away the posts of Kanto Kanreishiki (shogunal deputy for the Kanto region) and shugoshiki (provincial constables) of Echigo and Kazusa Provinces, which had been served by persons from Togoku (eastern provincies) samurai families for generations, such as Ujitsuna UTSUNOMIYA and Kunikiyo HATAKEYAMA; instead, an emerging power of Noriaki UESUGI took over them, and Uesugi clan became capable of serving these posts for generations (political changes of the Kanto region).
こうして、尊氏亡き後の幕府・鎌倉府によって代々の東国武家の畠山国清および宇都宮氏綱が務めていた関東管領職および越後・上野守護職は公式に剥奪され、新興勢力の上杉憲顕がその後釜に座り、上杉氏は代々その職に就くこととなった（関東の政変）。
