The Battle of Ivry took place on March 14, 1590, during the French Wars of Religion. It was a significant conflict between the forces of Henry IV of France, a Protestant, and the Catholic League led by Charles de Mayenne. The battle was fought near the town of Ivry-la-Bataille in Normandy and resulted in a decisive victory for Henry IV, solidifying his claim to the French throne. This battle was crucial in the struggle for control of France, as it marked a turning point in the conflict. Following his victory at Ivry, Henry IV gained greater support and eventually converted to Catholicism, which helped him unify the country and end the wars.
