The outcome of the defeat of Napoleon at Waterloo in 1815 was significant in ending his rule and restoring the monarchy in France. The defeat marked the conclusion of the Napoleonic Wars and established a period of peace in Europe, known as the Congress of Vienna. This event led to the reorganization of European borders and the emergence of a balance of power, which aimed to prevent further large-scale wars. It also led to the rise of nationalistic movements as various peoples sought their own identities and representations, changing the political landscape of Europe.
