The correct answer is "restore peace and stability to Europe."
The Treaty of Paris, signed on May 30th, 1814, ended the conflict between France and the coalition of Prussia, Austria, Russia, The United Kingdom, Portugal, Spain, Sweden, and a number of German States. The treaty set the borders of France and restored territories gained by this country during the Napoleonic Wars, bringing a period of political stability in Europe that would last until the First World War.
