European Grand Prix
The European Grand Prix was created as an honorific title by the AIACR, the FIA's predecessor in the organisation of motor racing events. The first race to receive the title was the Italian Grand Prix, in 1923; the French Grand Prix followed in 1924 and the Belgian Grand Prix in 1925. After a hiatus in 1929, the Belgian race received the title in 1930, becoming the last race to do so before World War II.
German Grand Prix
The first national event in German Grand Prix motor racing was held at the AVUS (Automobil Verkehrs und Übungs-Straße (Automobile Traffic and Practice Road)) race circuit in southwestern Berlin in 1926 as a sports car race. The AVUS circuit was made up of two 6-mile straights combined with two left-hand hairpins at each end. The first race at AVUS, in heavy rain, was won by Germany's native son, Rudolf Caracciola in a Mercedes-Benz. The event was marred by Adolf Rosenberger's crash into one of the marshals' huts, killing three people. The AVUS circuit was considered extremely dangerous even back then- so the event was moved. The German "Grand Prix" became an official event in 1929. Although it was raced on in the non-championship AVUS-Rennen in the 1930s which saw some of the fastest road races ever held, the Grand Prix would not return to AVUS until 1959 for a one-off appearance.
