Uesugi

The Uesugi rose from a Kyoto court family to become hereditary Kantō deputies under the Ashikaga shoguns. Their Yamanouchi and Ōgigayatsu branches competed for power in eastern Japan, but the latter fell to the Later Hōjō.

Uesugi Norimasa fled to Echigo and passed the family leadership to Nagao Kagetora, later known as Uesugi Kenshin. Kenshin fought Takeda Shingen at Kawanakajima, while his adopted son Kagekatsu lost much of his Aizu domain after the Battle of Sekigahara in 1600 and was transferred to Yonezawa.
