The Turkish Basketball Championship (Turkish: Türkiye Basketbol Şampiyonası) was a top-level basketball championship competition in Turkey, that was run by the Turkish Basketball Federation, from 1946 to 1967. In the 1966–67 season, the competition was replaced by the Turkish Basketball Super League (BSL).
The Basketball Super League (Turkish: Basketbol Süper Ligi; BSL), also known as the ING Basketbol Süper Ligi for sponsorship reasons, is the top men's professional basketball division of the Turkish basketball league system. It replaced the former Turkish Basketball Championship (1946–1967) to become the Turkish Basketball League (TBL) until 2015 when it adopted its current name while the TBL name became exclusive to the second-tier and third-tier divisions.
On April 25, 1955, the last game of the championship was Fenerbahçe against Galatasaray at Spor Sergi Sarayı. Galatasaray and Modaspor were in the championship race until the last game and they had the same number of points. Therefore, the last game was very important for both Galatasaray and Modaspor since the champion would be determined by total point difference. In the game against Galatasaray, Fenerbahçe officials withdrew their team from the match with just 44 seconds left to the end of the match due to Fenerbahçe being behind by 13 points, with no chance of turning the game. Thus the match could not be concluded. Nevertheless, the Federation of Sports declared that such behavior of the Fenerbahçe officials would not be acceptable and there were two domestic champions, Galatasaray and Modaspor, in that year. The trophy was split into two pieces and both clubs could keep these in their museums.[1][2][3]
