The warlord Oda Nobunaga eventually got tired of the competition, surrounded Mount Hiei with an army of samurai, and set fire to every temple on his way up the mountain, killing every monk who escaped the flames. Enryaku-ji was allowed to rebuild, but it was no longer allowed to maintain its own armies.
The involvement of the Tendai sect in warfare and power politics might seem odd or even hypocritical for a Buddhist denomination, but in a certain way it fits with the Tendai doctrine that true Buddha-hood is achieved in the midst of the world, not apart from it. This doctrine may well have been misused, but it has also led to Tendai sponsorship of poetry, visual art and other aspects of high culture, all of which still play a significant role in Tendai practice. As for the sohei, they no longer exist, and their techniques of fighting with the “naginata” or halberd and the “yari” or spear are all but forgotten.
