The American Football League (AAA – Division 2 – League) began playing matches in Canada in 1926, and then played against the National Football League (1930s) and Canadian football League (1940s). These were the first Major American Football (Gridiron) Internationals.
The National Football League began promoting American Football around the World, starting in the 1950s with a series of Internationals versus Canadian Football League teams, and then playing preseason games in first Canada in the 1960s, then in the 1970s Europe, Japan and Mexico. In 2007 the National Football League began playing regular season games in London, Toronto and Mexico City.
Major American Football Leagues have been played outside of the USA since the World League of American Football in 1991. With 6 teams in USA, one in Canada, and three in Europe, it was the first Official National Football League Development League (Division 2), as well as the first league of its kind to be played on a weekly basis on two continents (technically the USSR Soccer League was the first). It became a Europe-only league in 1995 and renamed NFL Europe in 1998 and was scrapped by the NFL in 2007 in favour of promoting the NFL in Europe through regular season game.
The European Leagues were replaced by the United Football League (USA 2009-2011), Elite Football League of India (2012), Legends Football Leagues (Canada 2012-13 and Australia 2013-14), China Arena Football League (2016), Pretty Girls Footbal l League (Mexico 2017) and Alliance of American Football (2019).
Beginning in 1984 AAA (Division 2) American Football Leagues began playing matches in Europe (USFL 1984, Arena Football League 1990s) or against World American Football Teams (Legends Football League USA v Legends Football League Canada 2010s, The Spring League v Japan American Football Association 2020).
