Battle of Agincourt, (October 25, 1415), decisive victory of the English over the French in the Hundred Years’ War. In 1413 the new king of England, Henry V, took the opportunity of a power struggle inside France to renew English claims to the French throne and invade. His victory against a much larger French army repeated the successes at the battles of Crécy and Poitiers, enabling him to dominate northern France.
