The Treaty of Vienne was signed in 1815, marking the end of the Congress of Vienna, which aimed to restore stability in Europe after the Napoleonic Wars. The treaty established a new balance of power among the major European nations, including the Austrian Empire, Prussia, Russia, and Great Britain. It sought to prevent future conflicts by redrawing national boundaries and reinforcing monarchies. Additionally, the treaty emphasized the importance of diplomacy and cooperation among nations. It laid the groundwork for a century of relative peace in Europe, known as the Concert of Europe, where major powers worked together to manage international relations and conflicts.
