The outcome of the Battle of Waterloo in 1815 was the decisive defeat of Napoleon Bonaparte, which led to the end of his rule and the restoration of the monarchy in France. This battle marked a turning point in European history, as it led to the establishment of a new balance of power in Europe, effectively curbing the expansionist ambitions of France. Following Waterloo, the Congress of Vienna sought to reshape Europe diplomatically, leading to nearly a century of relative peace and stability, often referred to as the Concert of Europe.
