Honnō-ji is most famous for the Honnō-ji incident, the assassination of the powerful warlord Oda Nobunaga, which occurred there on 21 June 1582. Nobunaga lodged at the temple with little protection before his invasion of the west, but was betrayed by his general Akechi Mitsuhide, who moved in superior forces by subterfuge, besieged the temple, and set it on fire. Knowing there was no way out for him, Nobunaga committed seppuku along with his attendant Mori Ranmaru.
