Starting around the Meio-no-seihen (明応の政変) in 1493, the shugo daimyo that had failed to regain authority were ousted from their positions by shugo-dai and kokujin, while those that succeeded in tightening the control of the kokujin further strengthened the provincial control.
そして、1493年（明応2）の明応の政変前後を契機として、低下した権威の復活に失敗した守護大名は、守護代・国人などにその地位を奪われて没落し、逆に国人支配の強化に成功した守護大名は、領国支配を一層強めていった。
