Cause → Event → Consequence
Akechi Mitsuhide, a retainer of Oda Nobunaga, betrayed his lord in the Honnō-ji Incident, forcing Nobunaga to commit seppuku and seizing control of Nobunaga's power and authority in the Kyoto region.
Thirteen days after the Honnō-ji Incident, Toyotomi Hideyoshi led Oda forces against Akechi Mitsuhide at Yamazaki, near present-day Kyoto Prefecture. The two armies clashed in a battle also called the Battle of Mt. Tennō, with Hideyoshi's forces decisively defeating Mitsuhide.
Hideyoshi's victory avenged Nobunaga's death and effectively transferred Nobunaga's authority and power to Hideyoshi himself, positioning him as the dominant figure in Japan and setting the stage for his eventual unification of the country.
