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.
Monaco Grand Prix Formula Three support race
The race was first held as a Formula Junior race in 1950, won by Stirling Moss, but it was only brought back as a permanent event in 1959. Formula Junior was replaced by Formula Two and Formula Three in 1964 and the support race was now held with F3 cars. A European Formula Three Championship was introduced in 1974 but the Monaco race was not part of it and instead attracted drivers from the various national and international F3 series held in Europe.
