The Battle of Waterloo, fought on June 18, 1815, is renowned as the decisive conflict where Napoleon Bonaparte was finally defeated. Located in present-day Belgium, the battle marked the end of the Napoleonic Wars and led to Napoleon's subsequent exile to the island of Saint Helena. A coalition army led by the Duke of Wellington and Prussian General Gebhard Leberecht von Blücher successfully faced Napoleon’s forces, marking a turning point in European history. Waterloo is often seen as the beginning of a new era in international relations, heralding the Congress of Vienna and significant geopolitical shifts across Europe.
