NFL Europe League was a professional American football league that functioned as the developmental minor league of the National Football League (NFL). Originally founded in 1989 as the World League of American Football, the league was envisioned as a transatlantic league encompassing teams from both North America and Europe. Initially, the WLAF consisted of seven teams in North America and three in Europe. It began play in 1991 and lasted for two seasons before suspending operations; while the league had been "wildly popular" in Europe, it failed to achieve success in North America. After a two-year hiatus, it returned as a six-team European league, with teams based in England, Germany, the Netherlands, Scotland, and Spain. NFL Europa was dissolved in 2007 due to its continued unprofitability and the NFL's decision to shift its focus towards hosting regular-season games in Europe; at the time of its closure, the league consisted of five German teams and one team based in the Netherlands.

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.
