The outcome of the Congress of Vienna in 1815 significantly altered European power dynamics. The congress aimed to restore stability and balance after the Napoleonic Wars, leading to the re-establishment of monarchies across Europe. The major powers—Austria, Prussia, Russia, and the United Kingdom—created a system of alliances that sought to prevent the rise of another dominant power. It also redrew national boundaries, restoring territories and creating buffer states. This conservative approach established a framework for European politics that persisted until World War I, emphasizing diplomacy and a balance of power to maintain peace.
