足利氏
The Ashikaga clan which ruled Japan during the Muromachi period established a branch government at their ancestral homeland of Ashikaga "shōen" in Shimotsuke to govern the Kantō region. However, by the late Sengoku period, this branch of the Ashikaga were very much weakened by the constant battles against the Uesugi clan, Takeda clan and Odawara Hojo clan, and were eventually dispossessed after the 1590 Battle of Odawara.
