In the beginning of the 20th century, Daytona Beach was known by racing enthusiasts as a place for setting land speed records. Before the speed record scene moved to the Bonneville Salt Flats, Daytona was the venue of choice. Fifteen speed records were set in Daytona between 1905 and 1935. After the heyday of speed racing, Daytona began to host race events.
The early days of racing were rather humble, with most drivers moonlighting as drivers for bootleggers. Moonshine runners would modify their vehicles to make them faster than the police cars that were chasing them, resulting in some rather ironic improvements in auto racing and automobiles in general. Once prohibition was ended, the natural choice for many of these drivers, who had developed quite a taste for speed.
In 1935 a mechanic by the name of William France Sr. moved to Daytona Beach to escape the Depression. Having followed the events in Daytona, he entered the 1936 Daytona race and finished fifth. By 1938 he was in charge of running the course. It occurred to France that people might enjoy watching the event, so he began to organize the racers. In the early days racers were frequently the victims of unscrupulous racing promoters. In 1947 in early December he organized talks between racers and promoters. These talks eventually became the sanctioning organization that is NASCAR, with standardized rules, a regular schedule and a championship.
The first NASCAR stock race was held at Charlotte Speedway in 1949. The cars were strictly stock, with no modifications from the factory. After a number of years, however, modifications for safety and performance were allowed. Eventually the cars became high performance cars that merely looked like stock cars.
