The occupied Rhineland made up 6.5% of Germany's total area and had a population of about seven million. While the negotiations for the Treaty of Versailles were in progress, the region was under a state of siege and the number of occupation troops stood at approximately 240,000 (220,000 French and 20,000 Belgian). By February 1920, a year after the Treaty had gone into effect, the number had dropped to 94,000 French and 16,000 Belgian troops. In March and April 1920, a violent workers'
uprising in the Ruhr district was suppressed by the German
Reichswehr with assistance from units of the paramilitary
Freikorps. As a reaction to the incursion of German troops into the demilitarised zone east of the Rhine, French troops temporarily occupied
Frankfurt am Main,
Darmstadt and several other smaller cities beginning on 6 April 1920. Because the
United States Senate did not ratify the Treaty of Versailles, the American representative, General
Henry Tureman Allen, was only an unofficial observer on the Commission, although either he or a deputy attended all Commission meetings, and when Allen attended he expressed his opinions freely. At the request of the
state of Prussia, to which the majority of the occupied territory belonged, German interests were represented by the newly created Reich Commissioner's Office for the Occupied Rhine Territories. The first Prussian state commissioner was
Karl von Starck; he was succeeded in 1921 by .
Bavaria also had a state commissioner, since a small part of its territory was also occupied. The legislative powers of the Commission, which had been granted to it in order to protect the occupying troops, were not precisely defined. The Commission was authorised to both approve and amend national laws affecting the Rhineland and decrees issued by Rhineland officials, making it de facto the supreme public authority in the occupied Rhineland. The Commission supervised German administration in the occupied territory through a system of district delegates who were placed at the side of the respective local German administrative officers. In March 1921, Germany created a special department within the Ministry of the Interior to handle matters relating to the occupied territories. In August 1923, the department became the cabinet-level
Reich Ministry for the Occupied Territories. It was tasked with safeguarding German interests in dealing with he occupying powers, including the IARHC, and with representing the interests of the occupied territories in the Berlin government. The separatist movements had ended by early 1924. Work in the factories and mines stopped, and the German government supported the region's idled workers through printing additional money, which led to the
hyperinflation that all but wrecked the German economy. During the course of the Ruhr occupation, 132 Germans were killed and approximately 188,000 evicted from their homes. Germans who fraternised could face stigmatisation or physical violence within their own communities.
End of the occupation The British occupation zone around Cologne was to have been vacated in January 1925, but it was delayed by the French due to disagreements about the German army's compliance with the armaments reduction requirements imposed on it in the Treaty of Versailles. As a result of the agreements reached in the
Locarno Treaties, British troops withdrew from their zone in January 1926. After Germany accepted the
Young Plan, which was negotiated in a second attempt to settle the issue of German reparations, the Allies agreed to evacuate the Rhineland by 30 June 1930, five years before the date set in the Treaty of Versailles. The occupation zone that included Koblenz was evacuated in November 1929, and the last of the occupying troops withdrew from the Mainz zone on 30 June 1930. The evacuation was followed by bloody German settlements with separatists who had cooperated with the French. In accordance with the Treaty of Versailles – and also the Locarno Treaties, in which Germany had voluntarily agreed to the demilitarisation of its territory west of a line drawn 50 kilometres east of the Rhine in 1925 – the area remained a demilitarised zone until
Adolf Hitler had it occupied by the
Wehrmacht in breach of the treaties on 7 March 1936. ==Occupying forces==
