The competition was originally launched as the A.B.B.A. National Championship in 1936, and was the first attempt by the Amateur Basketball Ball Association (A.B.B.A.) to develop an annual national basketball championship in England and Wales. The National Championship was initially structured as an end-of-season event to allow regional champions to compete against their peers from across England and Wales. It was governed by the Amateur Basket Ball Association (A.B.B.A.), a forerunner of the current
Basketball England organisation. During World War II, the competition was put on hiatus; the last pre-war winners, Birmingham Athletic Institute, retained the trophy for the duration of the hostilities. Following the introduction of the
National Basketball League (NBL) in 1972, the cup began a gradual decline in its influence on the English game as alternative national competitions became more established. The introduction of the NBL's own end-of-season playoffs in 1979 resulted in the competition being restructured into a season-long knockout tournament similar to football's
FA Cup, with the competition renamed the National Cup to avoid confusion with the league championship. This structure continued through the introduction of the independent, franchise-based
British Basketball League in 1987, though the cup was eventually truncated to a 16-team event for 1998 onwards, with the clubs holding a BBL franchise being joined by the top teams from the previous year's NBL Division 1 standings. This change in format came at the same time as the BBC began showing live coverage of the semi-finals and final. In 2003, the governance and competition structure of basketball in England underwent a period of reinvention, which included rebranding the NBL as the
English Basketball League and introducing new rules governing the use of import players across all
Basketball England competitions. These changes led to conflict with the
British Basketball League, which withdrew the support of all top-flight clubs and started their own breakaway competition. The withdrawal of the top-flight clubs led to the National Cup returning to a more open structure, with teams able to enter from all divisions of the NBL. This format largely remains to this day, with small variations in organisation during the early rounds. ==Format==
