France Ligue 1

Professionalism in French football did not exist until July 1930, when the National Council of the French Football Federation voted 128–20 in favour of its adoption. The founders of professionalism in French football are Georges Bayrou, Emmanuel Gambardella, and Gabriel Hanot. Professionalism was officially implemented in 1932.

In order to successfully create a professional football league in the country, the Federation limited the league to twenty clubs. In order to participate in the competition, clubs were subjected to three important criteria:

• The incoming club must have had positive results in the past.
• The incoming club must be able to pull in enough revenue to balance its finances.
• The incoming club must be able to successfully recruit at least eight professional players.

Many clubs disagreed with the subjective criteria, most notably Strasbourg, RC Roubaix, Amiens and Stade Français, while others like Rennes, due to fear of bankruptcy, and Lille, due to a conflict of interest, were reluctant to become professional. Lille's president, Henri Jooris, also chairman of the Ligue du Nord, feared his league would fold and proposed it become the second division of the new league. Eventually, many clubs earned professional status, though it became more difficult to convince clubs in the northern half of the country; Strasbourg, Roubaix and Amiens refused to accept the new league, while conversely Mulhouse, Excelsior AC Roubaix, Metz and Fives accepted professionalism. In southern France, clubs such as Marseille, Hyères, Montpellier, Nîmes, Cannes, Antibes and Nice were extremely supportive of the new league and accepted their professional status without argument.

The league's inaugural season of the all-professional league, called National, was held in 1932–1933. The 20 inaugural members of National were Antibes, CA Paris, Cannes, Club Français, Excelsior AC Roubaix, Fives, Hyères, Marseille, Metz, Mulhouse, Nice, Nîmes, Alès, Lille, Racing Club de France, Red Star Olympique, Rennes, Sochaux, Sète and Montpellier. The 20 clubs were inserted into two groups of 10 with the bottom three of each group suffering relegation to Division 2. The two winners of each group would then face each other in a final held at a neutral venue, which later turned out to the Stade Olympique Yves-du-Manoir. The first final was held on 14 May 1933 and it matched the winner of Group A, Olympique Lillois, against the runner-up of Group B, Cannes. Antibes, the winner of Group B, was supposed to take part in the final but was suspected of bribery by the French Football Federation and was disqualified. In the first final, Lillois were crowned the inaugural champions following the club's 4–3 victory. After the season, the league decided to retain the 14 clubs and not promote any sides from the second division. The league also agreed to change its name from National to simply Division 1. For the 1934–35 season, the league organised a legitimate promotion and relegation system bringing the total tally of clubs in the first division to 16. The number remained until the 1938–39 season.

Because of World War II, football was suspended by the French government and the Ligue de Football Professionnel, although its member clubs continued playing in regional competitions. During the "war championships", as they are called, professionalism was abolished by the Vichy regime and clubs were forced to participate in regional leagues, designated as Zone Sud and Zone Nord. Due to its non-association with the two leagues, the LFP and FFF do not recognise the championships won by the clubs and thus 1939–1945 is non-existent in the two organisations' view. Following the conclusion of the war and the liberation of France, professional football returned to France. The first division increased its allotment of clubs to 18. This number remained until the 1965–66 season when the number was increased to 20. In 2002, the league changed its name from Division 1 to Ligue 1.
