The Rentenmark (; RM) was a currency issued on 15 October 1923 to stop the hyperinflation of 1922 and 1923 in Weimar Germany, after the previously used "paper" Mark had become almost worthless. It was subdivided into 100 Rentenpfennig and was replaced in 1924 by the Reichsmark. History After the Occupation of the Ruhr in early 1923 by French and Belgian troops, referred to as the Ruhrkampf, the German government of Wilhelm Cuno reacted by announcing a policy of passive resistance. This caused the regional economy of the Ruhr, the industrial heartland of Germany, to almost stop. The occupation authorities reacted to strikes and sabotage with arrests and deportations. Those displaced and left without income by the Ruhrkampf and their families fell back on public income support. Tax revenues plunged as economic activity slowed. The government covered its need for funds mainly by printing money. As a result, inflation spiked and the Papiermark went into freefall on the currency market. Foreign currency reserves at the Reichsbank dwindled. As hyperinflation took hold, the cabinet of Cuno resigned in August 1923 and was replaced by the cabinet of Gustav Stresemann. After Stresemann reshuffled his cabinet in early October, Hans Luther became Minister of Finance. Working with Hjalmar Schacht at the Reichsbank, Luther quickly came up with a stabilization plan for the currency which combined elements of a monetary reform by economist Karl Helfferich with ideas of Luther's predecessor in office Rudolf Hilferding. With the help of the emergency law (Ermächtigungsgesetz) of 13 October 1923 which gave the government the power to issue decrees on financial and economic matters, the plan was implemented that same day, 15 October 1923. The newly created Rentenmark replaced the old Papiermark. Because of the economic crisis in Germany after the First World War, there was no gold available to back the currency. Luther thus used Helfferich's idea of a currency backed by real goods. The new currency was backed by the land used for agriculture and business. This was mortgaged (Rente is a technical term for mortgage in German) to the tune of 3.2 billion Goldmarks, based on the 1913 wealth charge called Wehrbeitrag which had helped fund the German war effort from 1914 to 1918. Notes worth RM 3.2 billion were issued. The Rentenmark was introduced at a rate of one Rentenmark to equal one trillion (1012) old marks, with an exchange rate of one United
