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.
Paris–Bordeaux–Paris
The race is sometimes referred to as the "I Grand Prix de l'A.C.F". This results from a retrospective political move that began in the early 1920s when French media represented many races held in France before the 1906 French Grand Prix as being Grands Prix de l'Automobile Club de France, despite their running pre-dating the formation of the Club. Hence, the 1906 race was said to have been the 9th edition of the Grand Prix de l'Automobile Club de France. The ACF itself adopted this reasoning in 1933, although some members of the Club dismissed it, "concerned the name of the Club was lent to the fiction simply out of a childish desire to establish their Grand Prix as the oldest race in the world."
