Following World War II, the Western Allies — the United States, United Kingdom, France, and the Benelux countries — sought to prevent German industrial rearmament by placing the Ruhr's coal and steel output under international supervision. The framework was agreed at the London Six-Power Conference in June 1948.
The International Authority for the Ruhr was formally established in 1949 with its seat in Düsseldorf. It regulated the coal and steel industries of the Ruhr area in West Germany on behalf of the Western Allied powers, ensuring output allocation and preventing unilateral German control over strategically vital heavy industries.
The IAR was abolished following the 1951 Treaty of Paris, with its functions transferred to the newly created European Coal and Steel Community. This transition marked a shift from punitive Allied oversight toward cooperative European supranational governance of heavy industry, laying groundwork for broader European integration.
Political Outcome
The IAR was dissolved in 1952 and its regulatory functions transferred to the European Coal and Steel Community under the 1951 Treaty of Paris.
Allied powers held direct supervisory control over Ruhr coal and steel industries
Control transferred to the supranational European Coal and Steel Community
