European Grand Prix
Between 1924 and 1948, the European Grand Prix was not a race in its own right but just an honorific title; one of the national Grands Prix was also designated as the European Grand Prix. The first race to be so named was the 1924 Nations Grand Prix, held at the Monza circuit in Italy. Until 1937, the winners of the race designated the European Grand Prix were awarded the title of European champion. In 1938, the European championship became decided over a series of races and the European Grand Prix designation was not used again until 1947, although no longer awarding the European championship title.
