The Ruhr
The Ruhr Agreement was imposed on the Germans as a condition for permitting them to establish the Federal Republic of Germany. By controlling the production and distribution of coal and steel (i.e. how much coal and steel the Germans themselves would get), the International Authority for the Ruhr in effect controlled the entire West German economy, much to the dismay of the Germans. They were however permitted to send their delegations to the authority after the Petersberg agreement. With the West German agreement to join the European Coal and Steel Community in order to lift the restrictions imposed by the IAR, thus also ensuring French security by perpetuating French access to Ruhr coal, the role of the IAR was taken over by the ECSC.
