[4] The 9th shōgun Ashikaga Yoshihisa died in 1489 on a battlefield of southern Ōmi Province.

[3] In 1493, Yoshitane lost in a power struggle against Hosokawa Masamoto and was formally replaced by the eleventh shōgun, Ashikaga Yoshizumi.

When Takakuni becomes Kanrei (shogun's deputy), Yoshitane strongly opposed him and he was driven out.

Takakuni arranged for the replacement of Yoshitane with the twelfth shōgun, Ashikaga Yoshiharu.

[9] However, when Yoshitane died prematurely, he was not succeeded by who he had chosen; rather, his father's newly designated heir was accepted by the shogunate as shōgun Yoshizumi.
