The Congress of Vienna was a diplomatic meeting held from 1814 to 1815, aimed at restoring stability in Europe after the Napoleonic Wars. Representatives from major powers, including Austria, Prussia, Russia, and Great Britain, gathered to negotiate territorial changes and establish a balance of power to prevent future conflicts. The congress resulted in significant territorial adjustments, such as the expansion of Prussia and the creation of the German Confederation. It also established the principle of legitimacy, restoring monarchies that had been overthrown. The decisions made at the congress shaped European politics for decades, promoting peace and cooperation among nations.
