The Congress of Vienna was a gathering of representatives of European kingdoms that was presided over by the Austrian Chancellor Klemens Von Metternich. The Congress was held in Vienna from 1814 to 1815. The goals of the Congress were to secure peace and stability in Europe and to ensure that revolutions did not destabilize the Continent, as they had in the previous 25 years. The Congress was initially able to establish an international system to prevent a general war, for several decades. However, it would lay the ground for future wars in Europe because it ignored the rise of nationalism among the peoples of Germany, Italy, Poland and others.
