Warring States Daimyo Warfare in the 1490s

Timeline

1. 1490–1492Kyoto · KinkiOn the fifth day of the seventh month of Tokuji 2 (July 22, 1490), Ashikaga Yoshiaki (later known as Yoshiharu) became the tenth Muromachi shogun with the support of the Hosokawa and Hino clans, but the shogunate's actual control over the shugo daimyo of the Kinai and neighboring provinces was far weaker than before.
2. 1495Odawara Castle · KantōTraditional military chronicles and local histories mostly record that in Meiō 4 (1495) Ise Shigetoshi (Hōjō Sōun) captured Ōmori Yoriyori's Odawara Castle, a landmark event for the emerging Warring States daimyo of Kantō. The official chronology of Odawara Castle also lists 1495, while noting alternative views dating it to Meiō 2 or as late as the early Eishō era, which must be preserved alongside it.
3. 1493–1499Tōkaidō and neighboring provinces · JapanIn Meiō 2 (1493) Hosokawa Masamoto deposed shogun Ashikaga Yoshiaki and installed Ashikaga Yoshizumi, an event known as the Meiō Coup, openly breaking the kanrei politics of the Kinai. Thereafter the Hosokawa, Rokkawa, and other powers continued to contend in neighboring provinces, while shugo daimyo and kokujin lords reorganized their domains through war and alliance.
