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 loss of the Kantō region to Hōjō Sōun in 1510 marked a significant development of Japan's Sengoku period.

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, and become one of the most major figures of the Sengoku period; Tamekage's son Uesugi Kenshin would likewise become a major warlord of the period, his rise with the Kantō as the center of his power base, as the result of Akisada's loss, a crucial element to his success.
