Miyoshi Nagayoshi

Timeline

1. 1532–1539Kyoto · Yamashiro ProvinceIn 1532 his father Miyoshi Motonaga was killed by Hosokawa Harumoto in league with the Ikkō-ikki; Nagayoshi, being young, was spared and continued to serve Harumoto. In 1539 he led some 2,500 men into Kyoto, using force to reclaim his father's and grandfather's positions in the Kinai. Shogun Ashikaga Yoshiharu at one point fled to Ōmi; after mediation by Rokkaku Sadayori, Nagayoshi was appointed shugo-dai of Settsu and took up residence in Yomikoshi Castle, thereafter using Settsu as his base and never withdrawing back to Awa.
2. 1539–1548Yomikoshi Castle, Settsu · Settsu ProvinceUsing Yomikoshi Castle as his base, Nagayoshi administered Settsu, successively defeating rivals such as Kizawa Nagamasa and Yūsa Nagamori, and rose to become the most powerful retainer of the Hosokawa house. He was already able to muster forces from Settsu, Kawachi, and elsewhere to enter Kyoto, his power surpassing that of his lord Harumoto. In 1548 he reconciled with Yūsa Nagamori and married his daughter, while simultaneously supporting Hosokawa Ujitsuna and openly betraying Harumoto.
3. 1548–1550Egiguchi, Settsu · Settsu ProvinceIn 1549 Nagayoshi defeated Harumoto and Miyoshi Masanaga at the Battle of Egiguchi, and Masanaga was killed in action. Harumoto and shogun Ashikaga Yoshiteru fled to Ōmi, the Hosokawa kanrei regime collapsed, and the Miyoshi regime was established. By 1550 Nagayoshi effectively controlled Kyoto and the key points of the Kinai, and shogunal orders required his approval. In 1552 he welcomed Yoshiteru back to the capital and installed Ujitsuna as kanrei; both became puppets.
4. 1552–1564Iimoriyama Castle, Kawachi · Kawachi ProvinceIn the 1550s Nagayoshi and Yoshiteru repeatedly clashed and reconciled; his brothers divided control of Awa, Sanuki, and Awaji, and their influence extended across the Kinai and Shikoku. He served as a sōban-shū and kanrei-dai of the shogunate, issuing orders in the shogun's name. After 1561 his younger brothers and heir died one after another, and Matsunaga Hisahide gained great power. In 1564 Nagayoshi died of illness at Iimoriyama Castle, and the Miyoshi coalition regime rapidly declined.
