The Treaty of Vienna, signed in 1815, is known for redrawing the map of Europe after the Napoleonic Wars. The treaty aimed to restore stability and order to Europe following the upheaval caused by Napoleon Bonaparte's conquests. Key decisions made at the Congress of Vienna included the restoration of monarchies, the re-establishment of territorial boundaries, and the principle of balance of power among European nations to prevent future conflict. The treaty's impact established a diplomatic framework that facilitated relative peace in Europe for several decades, often referred to as the "Concert of Europe."
