 The final limitations on German industrial levels were lifted after the establishment of the European Coal and Steel Community in 1951, though arms manufacture remained prohibited.With U.S. support, (as given in the September 1946 Stuttgart Speech), France in 1947 turned the coal rich Saarland into the Saar protectorate and integrated it into the French economy.The Franco-German conflict over the Saarland was later to prove one of the major hurdles to the integration of the European communities.
