The BAFANL (BAFA National Leagues) is the primary American football domestic league competition in Great Britain. Originally formed in 1983, the league is run by the British American Football Association to coordinate contact football within England, Scotland and Wales. The top level is the Premier Division and the BritBowl is the annual final championship game. The league was reformed in 2010 following the collapse of the British American Football League, which had run in a number of different guises since the early 1980s. Previous names of the league were the UKAFL (UK American Football League), the Budweiser League and the BNGL (British National Gridiron League). From 1998 until 2005 the league was known as the BSL (British Senior League). Tensions grew throughout 2009 between the directors of BAFL and those of the governing body the British American Football Association, and at the beginning of 2010 the BAFL formally, but unconstitutionally, withdrew from BAFA. This led to uproar from the teams within BAFL, ultimately signalling the end for BAFL as an entity. The league ceased operations on 1 April 2010 and was replaced by the BAFA Community Leagues for the 2010 season, rebranding in 2011 to become the BAFANL. Notable players to have come from the BAFANL who have gone on to play in the NFL are Efe Obada, Aden Durde, Jermaine Allen and Marvin Allen.

American football, also known as gridiron football, is a team sport played by two teams of eleven players on a rectangular field with goalposts at each end. The offense, the team with possession of the oval-shaped football, attempts to advance down the field by running with the ball or throwing it, while the defense, the team without possession of the ball, aims to stop the offense's advance and to take control of the ball for themselves. The offense must advance at least ten yards in four downs or plays; if they fail, they turn over the football to the defense, but if they succeed, they are given a new set of four downs to continue the drive. A game is won by the team with the higher number of points, which are scored primarily by advancing the ball into the opposing team's end zone for a touchdown or kicking the ball through the opponent's goalposts for a field goal.
