The Congress of Vienna, held from 1814 to 1815, was significant in reshaping Europe after the Napoleonic Wars. The main objective was to restore order and balance of power among the European nations to prevent future conflicts. The Congress established a framework for diplomatic relations that emphasized cooperation among great powers, leading to a period known as the "Concert of Europe." Key outcomes included the redrawing of national borders, restoration of monarchies, and the establishment of a balance that would largely maintain peace in Europe for decades, influencing international relations.
