Indian Super League
Football in India has existed in many forms since the game first arrived in the country during the 19th century with the first nationwide club competition, the Durand Cup, being founded in 1888. Despite India's early history in the game, the country's first nationwide football league did not begin until the semi-professional National Football League commenced in 1996. Prior to the creation of the National Football League, most clubs played in state leagues or select nationwide tournaments.
National League (English football)
Most of the National League clubs are fully professional, while most National League North and National League South clubs are semi-professional. The professional clubs are sometimes clubs which have been in the English Football League (EFL) in the past, as opposed to those which have always been non-League. The National League is the lowest of the five nationwide football divisions in England, below the Premier League and the three divisions of the EFL, and is the top tier of the National League System of non-League football. The National League North and National League South form the sixth tier of English football. The National League consisted of only one division until 2004, but expanded as part of an extensive restructuring of the National League System which took effect beginning with the 2004–05 season.
