was founded in 1719 for Uesugi Katsuchika, the fourth son of Uesugi Tsunanori, the 4th "daimyō" of Yonezawa Domain, who assigned him 10,000 "koku" of new rice revenues. The domain continued as a subsidiary of Yonezawa Domain, ruled by a succession of younger sons of the parent house. Following the defeat of Yonezawa Domain in the Boshin War, Yonezawa Shinden Domain was reabsorbed into its parent domain, and its final "daimyō", Uesugi Katsumichi was later granted the kazoku peerage title of "shishaku" (viscount).
