The English football league system, also known as the football pyramid, is a series of interconnected leagues for men's association football clubs in England, with six teams from Wales and one from Guernsey also competing. The system has a hierarchical format with promotion and relegation between leagues at different levels, allowing even the smallest club the theoretical possibility of ultimately rising to the very top of the system, although in practice it would take a team at the bottom levels at least two decades of consistently finishing at or near the top of each successive league to reach the top level, and even then additional restrictions, particularly in regard to stadium facilities, would then come into effect at the highest levels that could prevent a club from being allowed access to the top levels. There are more than 140 individual leagues, containing more than 480 divisions.
The exact number of clubs varies from year to year as clubs join and leave leagues or fold altogether, but an estimated average of 15 clubs per division implies that more than 7,000 teams of nearly 5,300 clubs are members of a league in the English men's football league system.
As there are no official definitions of any level below 11, any references to the structure at level 12 and below should not be regarded as definitive.
The pyramid for women's football in England runs separately to nine tiers and some England-based men's clubs play outside the English football league system.
The (English) Football League was created in 1888 by Aston Villa director William McGregor. It was dominated by those clubs who had supported professionalism. The twelve founding members consisted of six from Lancashire (Blackburn Rovers, Burnley, Bolton Wanderers, Accrington, Everton and Preston North End) and six from the Midlands (Aston Villa, Derby County, Notts County, Stoke, West Bromwich Albion and Wolverhampton Wanderers). No sides from the South including London initially participated.
The system consists of a pyramid of leagues, bound together by the principle of promotion and relegation. A certain number of the most successful clubs in each league can rise to a higher league, whilst those that finish at the bottom of their league can find themselves sinking down a level. In addition to sporting performance, promotion is usually contingent on meeting criteria set by the higher league, especially concerning appropriate facilities and finances.
