The battle that marked the end of Napoleon Bonaparte's rule in France was the Battle of Waterloo, fought on June 18, 1815. This decisive battle involved the forces of the Duke of Wellington representing the British-led coalition against Napoleon's army. After a series of military campaigns, Napoleon returned from exile in Elba, leading to his brief return to power known as the Hundred Days. However, at Waterloo, he faced a coalition army and was ultimately defeated, leading to his final exile to Saint Helena. The outcome of this battle significantly altered the trajectory of European politics and the balance of power.
