The First Congress of Vienna, held in 1815 after the Napoleonic Wars, was significant for restoring political stability in Europe. Delegates aimed to re-establish **balance of power** among the major European nations and prevent future conflicts through a system of collective decisions. Key figures, such as Prince Metternich of Austria, sought to contain revolutionary ideas and maintain monarchies. The lasting impact included the formation of a new framework for international relations, influencing European political dynamics for decades, and laying the groundwork for future diplomatic congresses, creating a temporary peace and stability in Europe.
