===European non-championship racing===
In the early years of Formula One, before the world championship was established, there were around twenty races held from late Spring to early Autumn in Europe, although not all of these were considered significant. Most competitive cars came from Italy, particularly [[Alfa Romeo in Formula One|Alfa Romeo]]. After the start of the world championship, these non-championship races continued. In the 1950s and 1960s, there were many Formula One races which did not count for the World Championship; in {{f1|1950}} a total of twenty-two Formula One races were held, of which only six counted towards the World Championship.<ref name="ESPN" /> In 1952 and 1953, when the world championship was run to Formula Two regulations, non-championship events were the only Formula One races that took place.

Some races, particularly in the UK, including the [[Race of Champions (Brands Hatch)|Race of Champions]], [[Oulton Park International Gold Cup]] and the [[International Trophy]], were attended by the majority of the world championship contenders. Other smaller events were regularly held in locations not part of the championship, such as the [[Syracuse Grand Prix|Syracuse]] and [[Danish Grand Prix|Danish]] Grands Prix, although these only attracted a small amount of the championship teams and relied on private entries and lower Formula cars to make up the grid.<ref name="LastnonchampF1" /> These became less common through the 1970s and 1983 saw the last non-championship Formula One race; the [[1983 Race of Champions]] at Brands Hatch, won by reigning World Champion [[Keke Rosberg]] in a Williams-Cosworth in a close fight with American [[Danny Sullivan]].<ref name="LastnonchampF1" />
