The battle that effectively ended Napoleon's rule and ultimately led to his exile was the Battle of Waterloo, fought on June 18, 1815. This decisive confrontation involved Napoleon's forces against the Seventh Coalition, primarily composed of British and Prussian troops. The coalition forces, led by the Duke of Wellington and Gebhard Leberecht von Blücher, successfully defeated Napoleon, marking the end of his Hundred Days return to power following his previous abdication. After this defeat, Napoleon was captured and exiled to Saint Helena, where he spent the remainder of his life, fundamentally altering the course of European history.
