足利将軍家
The Sengoku Period is marked by social upheaval, political intrigue and near-constant military conflict. Less than a century after the end of the Nanboku-chō Wars, peace under the relatively weak Ashikaga shogunate was disrupted by the outbreak of the Ōnin War (1467–1477). This was a civil war between the Ashikaga shogunate and numerous daimyō. The ancient capital of Kyoto was converted into a battlefield and a heavily fortified city that suffered severe destruction.
