The outcome of the Congress of Vienna in 1815 profoundly impacted European diplomacy by facilitating a balance of power aimed at preventing future wars. Major powers, including Austria, Prussia, Russia, and Britain, aimed to restore the pre-Napoleonic political order. The principles established at the Congress led to nearly a century of relative peace in Europe, often referred to as the Concert of Europe. This diplomatic framework encouraged collaboration among the great powers and was instrumental in managing conflicts, laying the groundwork for diplomatic practices that would shape future international relations.
