Uesugi Akisada
From Wikipedia, the free encyclopedia
Uesugi Akisada (上杉顕定?) (1454-1510) was a samurai of the Uesugi clan, and shugo (Constable) of Echigo province, succeeding Uesugi Fusayoshi to that post.
His deputy (shugo-dai), Nagao Tamekage, rose up against him in 1510 with the help of Hōjō Sōun, seizing the province and killing Akisada. Sōun, with Tamekage's help, would go on to conquer most of the Kantō region.
