Uesugi Zenshū

nihongo|Uesugi Zenshū|上杉禅秀|(died 1417), also known as Uesugi Ujinori, was the chief advisor to Ashikaga Mochiuji, an enemy of the Ashikaga shogunate in feudal Japan. When he was rebuked by Mochiuji in 1415, and forced to resign, Zenshū organized a rebellion.

Zenshū received aid for his rebellion from nearly half the daimyo in the northern and eastern provinces, and took Kamakura. Mochiuji was forced to flee the city. However, despite pursuing similar goals to those of the shogunate ("bakufu"), Zenshū was still rebelling against his lord, and so the "bakufu" had no choice but to send troops to stop him. In 1417, Zenshū and his allies found themselves surrounded. They fled to Kamakura's Tsurugaoka Hachiman-gū, where Zenshū committed "seppuku".

The rebellion did not end with Zenshū's death, however, and neither did Mochiuji's opposition to it. For more than five years, Mochiuji continued to attack Zenshū's allies, including the Oda clan, Takeda family, and nobles of Musashi Province. Anger towards Mochiuji and his office only continued to grow, until the "bakufu" took action to stop him in 1423.
