Grand Prix motor racing has its roots in organised automobile racing that began in France as far back as 1894. It quickly evolved from a simple road race from one town to the next, to endurance tests for car and driver. Innovation and the drive of competition soon saw speeds exceeding 100 mph (161 km/h), but because the races were held on open roads there were frequent accidents with the resulting fatalities of both drivers and spectators.
Grand Prix motor racing eventually evolved into formula racing, and Formula One can be seen as its direct descendant. Each event of the Formula One World Championships is still called a Grand Prix.

The origins of organised racing
The first event to carry the name Grand Prix was the Grand Prix de Pau in 1901,
Races in this period were heavily nationalistic affairs, with a few countries setting up races of their own, but no formal championship tying them together. The rules varied from country to country and race to race, and typically centered around maximum (not minimum) weights in an effort to limit power by limiting engine size indirectly (10–15 L engines were quite common, usually with no more than four cylinders, and producing less than 50 hp). The cars all had mechanics on board as well as the driver, and no one was allowed to work on the cars during the race except for these two. A key factor to Renault winning this first Grand Prix was held to be the detachable wheel rims (developed by Michelin), which allowed tire changes to occur without having to lever the tire and tube off and back on the rim. Given the state of the roads, such repairs were frequent.

The first Grands Prix
For the most part, races were run over a lengthy circuit of closed public roads, not purpose-built private tracks. This was true of the Le Mans circuit of the 1906 Grand Prix, as well as the Targa Florio (run on 93 miles (150 km) of Sicilian roads), the German Kaiserpreis circuit (75 miles (121 km) in the Taunus mountains), and the French circuit at Dieppe (a mere 48 miles (77 km)), used for the 1907 Grand Prix. The exceptions were the steeply banked egg-shaped near oval of Brooklands in England, completed in 1907, the Indianapolis Motor Speedway, first used in 1909 with the first Indianapolis 500-Mile Race in 1911, and the Autodromo Nazionale Monza, in Italy, opened in 1922.
In 1922, Italy became the first country outside France to host an automobile race using the name Grand Prix (or Gran Premio), run at Monza. This was quickly followed by Belgium and Spain (in 1924), and later spread to other countries. Strictly speaking, this still wasn't a formal championship, but a loose collection of races run to various rules. (A "formula" of rules had appeared just before World War I, finally based on engine size as well as weight, but it was not universally adopted.)
In 1924, however, many national motor clubs banded together to form the Association Internationale des Automobile Clubs Reconnus (AIACR), whose Commission Sportive Internationale (CSI) was empowered to regulate Grand Prix and other forms of international racing. Since the inception of Grand Prix racing, competitions had been run in accordance with a strict formula based on engine size and vehicle weight. These regulations were virtually abandoned in 1928 with an era known as Formula Libre when race organisers decided to run their events with almost no limitations. From 1927 to 1934, the number of races considered to have Grand Prix status exploded, jumping from five events in 1927, to nine events in 1929, to eighteen in 1934 (the peak year before World War II).

Racecourse development
Important individual and corporate names emerged during this time which would change the face of automobile design and engineering:
The 1933 Monaco Grand Prix was the first time in the history of the sport that the grid was determined by timed qualifying rather than the luck of a draw. All the competing vehicles were painted in the international auto racing colors:
Beginning in 1934, the Germans stopped painting their cars, after the paint had been left off a Mercedes-Benz W25 in an effort to reduce weight. The unpainted metal soon had the German vehicles dubbed by the media as the "Silver Arrows".
French cars continued to dominate (led by Bugatti, but also including Delage and Delahaye) until the late 1920s, when the Italians (Alfa Romeo and Maserati) began to beat the French cars regularly. At the time, the Germans engineered unique race vehicles as seen in the photo here with the Benz aerodynamic "teardrop" body introduced at the 1923 European Grand Prix at Monza by Karl Benz.
In the 1930s, however, nationalism entered a new phase when the Nazis encouraged Mercedes and Auto Union to further the glory of the Reich. (The government did provide some money to the two manufacturers, but the extent of the aid into their hands was exaggerated in the media; government subsidies amounted to only about 10% of the costs of running the two racing teams.) The two German marques utterly dominated the period from 1934 to 1939, winning all but three of the races run in those years. The cars by this time were single-seaters (the riding mechanic vanished in the early 1920s), with 8 to 16 cylinder supercharged engines producing upwards of 600 hp (450 kW) on alcohol fuels.
As early as October of 1923, the idea of an automobile championship was discussed at the annual fall conference of the AIACR (Association Internationale des Automobile Clubs Reconnus) in Paris. However, discussion centered around 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 800 km 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 1935, and was competed every year until the outbreak of World War II in 1939.

In 1946, following World War II, there were only four races of Grand Prix caliber held. Rules for a Grand Prix World Championship had been laid out before World War II, but it took several years afterward until 1947 when the old AIACR reorganized itself as the Fédération Internationale de l'Automobile or "FIA" for short. Headquartered in Paris, at the end of the 1949 season it announced that for 1950 they would be linking several national Grands Prix to create Formula One with a World Championship for drivers, although due to economic difficulties the years 1952 and 1953 were actually competed in Formula Two cars. A points system was established and a total of seven races were granted championship status including the Indianapolis 500. The first World Championship race was held on 13 May at Silverstone in the United Kingdom.
The Italians once again did well in these early World Championship races, both manufacturers and drivers. The first World Champion was Giuseppe Farina, driving an Alfa Romeo. Ferrari appeared at the second World Championship race, in Monaco, and has the distinction of being the only manufacturer to compete during the entire history of the sport, still competing in 2006. The Formula One World Championship is still running today.
