The focus of the Congress of Vienna in 1815 was to restore stability and order to Europe following the turmoil caused by the Napoleonic Wars. The congress aimed to re-establish traditional monarchies and create a balance of power among European nations to prevent future conflicts. Key diplomatic leaders, including Austria's Klemens von Metternich, sought to strengthen conservative forces and suppress revolutionary movements. Agreements made during the congress reshaped Europe's political landscape and established a framework for international relations, significantly affecting European diplomacy for decades. The principles agreed upon influenced the continent's stability up to the outbreak of World War I.
