The German Democratic Republic (Deutsche Demokratische Republik (DDR)) was established in the aftermath of World War II in 1949. Also known as East Germany, the DDR existed as an Eastern Bloc state until German reunification in 1990. The first DDR circulating paper money was earlier German rentenmark and reichsmark notes with currency reform stamps affixed. The Deutsche Notenbank issued paper money denominated in Deutsche marks between 1948 and 1955, and then simply marks from 1964 to 1970. The Staatsbank der DDR issued paper money denominated in marks from 1971 to 1989.
