Cause

During Japan's Sengoku period, the powerful sōhei (warrior monks) of Enryaku-ji monastery on Mount Hiei had long wielded significant political and military influence. Their opposition to Oda Nobunaga's campaigns for unification made them a target. Nobunaga viewed their resistance as an obstacle to his consolidation of central power in Japan.

Event

On September 30, 1571, Oda Nobunaga besieged Mount Hiei and attacked the monasteries of Enryaku-ji. Historical accounts claim he ordered the killing of monks, scholars, priests, women, and children on the mountain, along with the destruction of the monastic complex. Recent archaeological work, however, suggests the destruction may have been less total than traditional sources indicate.

Consequence

The siege effectively dismantled the military and institutional power of the Enryaku-ji warrior monks. While the full extent of the destruction remains debated, the event demonstrated Nobunaga's willingness to use extreme force against religious institutions and contributed to the broader weakening of Buddhist political power during his campaign to unify Japan.
