The primary outcome of the Napoleonic Wars in Europe was the dramatic reshaping of the continent's political landscape. Following the conflict, which lasted from 1803 to 1815, the Congress of Vienna convened to restore stability and order, leading to significant territorial rearrangements. The defeat of Napoleon Bonaparte resulted in the decline of French dominance and the rise of Britain as a primary power. The Congress established a balance of power intended to prevent future widespread conflict in Europe. Additionally, revolutionary ideas about nationalism and democracy spread, setting the stage for future uprisings and political changes across Europe in the 19th century.
