Oda Nobunaga (1534–1582) was a Japanese warlord and political leader of the Sengoku period. He overthrew the Ashikaga shogunate, expanded his control across much of central Japan, and is remembered as one of the three unifiers of Japan. His campaigns helped create the conditions for national unification completed after his death.

Early life and rise to power

Nobunaga was born in Owari province in 1534. He emerged as a powerful daimyō during the unstable Sengoku period and first consolidated power in his home region before expanding beyond it.

Military campaigns and rule

He defeated rival forces, captured Kyōto, and ended the Ashikaga shogunate in 1573. His authority later extended over much of central Japan, and he governed as a dominant military ruler.

Religion and policy

Nobunaga weakened the political power of Buddhist institutions, including the destruction of Enryaku-ji in 1571. He also allowed Jesuit missionaries to operate in Kyōto, largely for political reasons.

Death and legacy

Nobunaga was killed in 1582 during the Honnō-ji Incident after being attacked by a discontented general. His death did not end the unification process, which was completed by his successors.
