It is widely believed that doping (predominantly anabolic steroids) allowed East Germany, with its small population, to become a world leader in the following two decades. It won a large number of Olympic and world gold medals and records. A number of athletes subsequently failed doping tests and others were suspected of taking performance-enhancing drugs. However, in many cases where suspicions existed, no proof of wrongdoing was uncovered. As a result, the majority of records and medals won by East German athletes still stand. Aside from an extensive doping programme, East Germany invested significantly in sport, particularly in Olympic sports, for reasons of prestige, propaganda and rivalry with West Germany. It had an extensive state bureaucracy to select and train promising athletes and world-class coaches.
