The significance of the Congress of Vienna, held from 1814 to 1815, lies in its efforts to restore political order and stability in Europe following the Napoleonic Wars. Major powers, including Austria, Britain, Russia, and Prussia, convened to discuss territorial boundaries and the balance of power. The Congress aimed to prevent future conflicts by establishing a framework for diplomacy and cooperation, promoting the principle of legitimacy to restore monarchies, and containing revolutionary movements. Its decisions shaped European politics for decades, emphasizing a conservative approach to governance and serving as a precursor to later international treaties.
