The government was established only by the talent of Nagayoshi himself and the existence of the limited number of personnel, including Nagayoshi's younger brother Yoshikata MIYOSHI, Fuyuyasu ATAGI, Kazumasa SOGO and his heir Yoshioki MIYOSHI.
その政権は長慶個人の才能と実弟の三好義賢・安宅冬康・十河一存らと嫡男の三好義興という限られた人物の存在によって成立しているに過ぎなかった。
