Before the introduction of the National Division, the former Turkish Football Championship was held as a national championship in Turkey. Its tournament system was based on a knockout tournament, contested between the winners of each of the country's top regional leagues. In the late 1920s the demand for a national football league was growing in the general Turkish public, which showed in the country's newspapers and magazines, where the European counterparts were given as examples. In 1937 that demand was fulfilled, as the Millî Küme was founded and began in March that year. Eligible for the league competition where the top placed teams of the Istanbul, Ankara, and İzmir regional leagues, which where the strongest leagues in those decades. An exception was made in 1941, when 1940 Turkish Football Championship winners Eskişehir Demirspor and a third club from Ankara were included. In 1940 the Turkish Football Federation decided to resume the Turkish Football Championship. As a result both national championships were held at the same time from 1940 to 1950. The main differences between both tournaments were the competition systems and the qualification criteria. The National Division became the most popular and most important football competition in Turkey, overshadowing the Turkish Football Championship, since it was played in a league format with away matches. In 1944 a special super cup, the Prime Minister's Cup, was introduced by the TFF. It was competed by the winners of both championships. The Prime Minister's Cup was one of the earliest football super cups in the world. The cup was held in that format until 1950, when the National Division concluded.
Competition format
There were eight clubs in the National Division. The four highest placed teams in the Istanbul Football League and the top two teams from the Ankara League and İzmir League at the end of the season qualified for the National Division. The competition was played within a year, it started just after the conclusion of the aforementioned regional leagues. The competition format was based on a double round-robin system, that means each club played the others twice, once at their home stadium and once at that of their opponents', for 14 games. Teams received three points for a win, two points for a draw, and one point for a loss. No points were awarded for a forfeit/regulation loss. Teams were ranked by total points, then goal average. There was no system of promotion and relegation, since the National Division was the only national league and there was no lower division.
