Miyoshi clan
On November 9, 1568, Nobunaga entered Kyoto, drove out the Miyoshi clan, who fled to Settsu, and installed Yoshiaki as the 15th shogun of the Ashikaga Shogunate. However, Nobunaga refused the title of shogun's deputy (Kanrei), or any appointment from Yoshiaki. As their relationship grew difficult, Yoshiaki secretly started an anti-Nobunaga alliance, conspiring with other daimyos to get rid of Nobunaga, even though Nobunaga had great respect for the Emperor Ōgimachi.
