Spanish Grand Prix
The first Spanish Grand Prix in 1913 was not actually run to the Grand Prix formula of the day, but to touring car rules, taking place on a 300-kilometre road circuit at Guadarrama, near Madrid, on the road to Valladolid.
Grand Prix motor racing
As early as October 1923, the idea of an automobile championship was discussed at the annual autumn conference of the AIACR (Association Internationale des Automobile Clubs Reconnus) in Paris. However, discussion centered on the increased interest in racing by manufacturers and holding the first European Grand Prix at Monza in 1923. The first World Championship took place in 1925, but it was for manufacturers only, consisting of four races of at least in length. The races that formed the first Constructors' Championship were the Indianapolis 500, the European Grand Prix, and the French and Italian Grands Prix. A European Championship, consisting of the major Grand Prix in a number of countries (named "Grandes Epreuves") was instituted for drivers in 1931, and was competed every year until the outbreak of World War II in 1939 with the exception of 1933 and 1934.
