However, the resistance from the old power did not stop, and Takamasa HATAKEYAMA, one of sankanrei (three families in the post of kanrei, or shogunal deputy) and Yoshikata ROKKAKU, the hankoku shugo (military governor in charge of the half area of the province) and male cousin of Harumoto HOSOKAWA raised rebellion against Miyoshi. With the struggle with them, Nagayoshi lost his brother Yoshikata MIYOSHI in the battle of Kumeda (present Kishiwada City). He survived his younger brothers (Kazumasa SOGO, Fuyuyasu ATAGI), and he himself died at the age of 41. After the death of Nagayoshi, the adopted child Yoshitsugu MIYOSHI, who was from the Miyoshi clan, succeeded. But as he was so young, Hisahide MATSUNAGA, the karo (chief retainer) and Miyoshi sanninshu (three chief retainers of the Miyoshi clan) took the actual power, and Yoshitsugu was just their puppet. With the successive deaths of Nagayoshi and his younger brothers and as the result of Hisahide and sanninshu bickering over the leadership, Miyoshi clan extremely declined in strength.
