ルール占領
On 11 January 1923 the Occupation of the Ruhr was carried out by the invasion of French and Belgian troops into the Ruhr. The French Prime Minister, Raymond Poincaré, was convinced that Germany failed to comply the demands of the Treaty of Versailles. On the morning of 31 March 1923, the culmination of this French-German confrontation occurred when a small French military command, occupied the Krupp car hall to seize several vehicles. This event caused 13 deaths and 28 injured. The occupation of the Ruhr ended in summer 1925.
