Answer
Hideyoshi succeeded Oda Nobunaga after the Honnō-ji Incident in 1582. The incident occurred when Akechi Mitsuhide, a general in Nobunaga's army, betrayed him and killed him in a surprise attack. Hideyoshi, who was Nobunaga's top general at the time, quickly rallied the troops and defeated Mitsuhide. He then took over Nobunaga's position as the leader of the Oda clan and continued Nobunaga's conquest of Japan.
