Decline of Ashikaga Shogunate Authority (1501–1510)

Timeline

1. 1501–1507Kyoto · KyotoAshikaga Yoshizumi became shogun in 1494, but real power lay with Hosokawa Masamoto and his successors. After 1501, the conflict between Hosokawa Takakuni and Miyoshi Motonaga intensified, and the shogunate became a puppet tool over which the two sides contended, further hollowing out the shogun's authority.
2. 1508Kyoto · KyotoHosokawa Takakuni expelled Yoshizumi and installed Ashikaga Yoshitane as shogun again, creating the unprecedented situation of two rival shoguns, Yoshizumi and Yoshitane, standing side by side. The legitimacy of the shogunate as the nation's supreme political institution suffered a fatal blow.
3. 1508–1510Japanese archipelago · JapanBy 1510, the shogunate's restraint over the shugo daimyō of distant provinces was nearly nonexistent; kokujin groups fought frequent battles in each province, and powers such as Ōuchi Yoshihiro and Amako Tsunehisa went their own way. Though the Muromachi shogunate survived in name, it had in fact been reduced to a local Kyoto regime, and the Sengoku period arrived in full.
