[1] The Amateur Football Combination is one of the biggest adult football leagues in Europe,[2] with around 75 clubs and 200 teams playing Saturday afternoons in and around London and the Home Counties from September through to May, and comprises more than 1% of adult male 11-a-side football teams in England.

[citation needed] The AFC is an adult male league affiliated to the Amateur Football Alliance (AFA), with clubs that also compete from London FA, Middlesex FA and Surrey FA, and was formed in 2002 by the merger of the Old Boys' Football League (1907) and Southern Olympian League (1911) and subsequently merging with the London Financial Football Association (itself comprising the London Banks Football Association, 1900 and the London Insurance Football Association, 1908) in 2006.

The league is divided into four sections using a pyramid system, but plays outside of the "football pyramid" - the top teams do not progress into semi-professional leagues:

Almost all clubs also enter the London Old Boys Cups.

In 2006 the AFC launched its "Spirit of Football" campaign, emphasising and promoting fair play and respect for all within the game, a concept later embraced nationally within the Football Association's "Respect" campaign.
