応仁の乱
By the end of the Warring States period only a dozen or so warlord families remained. The most important development to come out of the Ōnin War was the ceaseless civil war that ignited outside the capital city. Hosokawa tried to foment civil strife in the Ōuchi domains, for instance, and this civil strife would eventually force Ōuchi to submit and leave. From the close of the Ōnin War, this type of civil strife, either vassals striving to conquer their "daimyō" or succession disputes drawing in outside "daimyō", was endemic all throughout Japan.
