Which conflict's disruption led to the decline of strong central authority and contributed to decentralized power in Japan, culminating in the rise of regional power?

• A. Gempei wars
• B. Onin War
• C. Footbinding
• D. Taika reforms

Answer: (B)

Disruptions to central authority arise when a long, internal power struggle weakens the ruling regime so much that it can no longer enforce its will over distant provinces. In Japan, the Onin War did exactly that. Fought in the mid-15th century, it pitted rival aristocratic factions against each other and crippled the Ashikaga shogunate’s ability to govern Kyoto and maintain order. With the center fractured and resources scarce, regional military leaders—later known as daimyō—began building their own power bases in the provinces, effectively ruling their territories with considerable autonomy. This collapse of centralized control set off the Sengoku period, a time of widespread military conflict and regional fragmentation, culminating in the rise of powerful regional rulers.

By comparison, the Gempei Wars helped establish the Kamakura shogunate but did not produce the same extended breakdown of central authority across Japan; the Taika reforms were attempts to strengthen central control in earlier centuries, not to decentralize it; footbinding is a Chinese cultural practice and not related to Japan’s political development.
