The Battle of Waterloo, fought on June 18, 1815, is historically significant as it marked the end of the Napoleonic Wars and the final defeat of Napoleon Bonaparte. This decisive battle took place near Waterloo in present-day Belgium, involving a coalition of British-led forces and Prussian troops against Napoleon's army. The defeat effectively ended Napoleon's rule and led to his exile to Saint Helena. Waterloo reshaped the political landscape of Europe, resulting in a period of relative peace known as the Concert of Europe. It also reinforced the balance of power principle and led to the establishment of new alliances and political systems.
