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.

During this period a lot of changes of rules occurred. There was a mass start for the first time at the 1922 French Grand Prix in Strasbourg. The 1925 season was the first season during which no riding mechanic was required in a car, as this rule was repealed in Europe after the death of Tom Barrett in previous year. At the 1926 Solituderennen a well thought-out system, with flags and boards, giving drivers tactical information, was used for the first time by Alfred Neubauer, the racing manager of the Mercedes-Benz team.
