National Football League (India)
The National Football League (commonly known as the NFL) was an association football league competition in India between 1996 and 2007 which was organised into three divisions. The league is now transformed into the I-League and continues with that name. The "Premier Division" of the league was first introduced in 1996, though the country already had a long history in the sport thanks to the likes of the IFA Shield and the Federation Cup. In fact, the Santosh Trophy (started in 1941) was the top football competition in the country before the then National Football League started.
English football league system
The top tier of non-League football is the National League. It contains a national division (National League) of 24 clubs (Level 5), and is the lowest level with a single nationwide league. There are two divisions at Level 6, covering the north (National League North) and south (National League South), with 22 clubs each. Some of these clubs are full-time professional and the others are semi-professional. Below the National League, some of the stronger clubs are semi-professional, but continuing down the tiers, soon all the clubs are amateur. Lower-level leagues also tend to cater for progressively smaller geographic regions.
