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.
Grand Prix motor racing
In 1904, many national motor clubs banded together to form the Association Internationale des Automobile Clubs Reconnus (AIACR). In 1922 the Commission Sportive Internationale (CSI) was empowered on behalf of AIACR to regulate Grand Prix racing and other forms of international racing. Since the inception of Grand Prix racing, competitions had been run in accordance with a strict formula based on engine size and vehicle weight. These regulations were virtually abandoned in 1928 with an era known as "Formula Libre" when race organisers decided to run their events with almost no limitations. From 1927 to 1934, the number of races considered to have Grand Prix status exploded, jumping from five events in 1927, to nine events in 1929, to eighteen in 1934 (the peak year before World War II).
