The National Football League (NFL) was the men's highest level of the Indian football league system from 1996 to 2007.[2] Founded by the All India Football Federation (AIFF) in 1996, the NFL was the first football league in India to be organized on a national scale. The AIFF then added a second division in 1997 and a third division was soon added by the governing body in 2006. The NFL was eventually replaced by the I-League for the 2007–08 season in order to professionalize the sport in India.
As well as league competition, clubs in the NFL would also participate in the two main domestic cup competitions, the Federation Cup and Durand Cup. The NFL champions would also participate in the Indian Super Cup against the Federation Cup champion. NFL players could also participate in the state-based Santosh Trophy competition.
In 2001, in order to help promote the development of young Indian players, the AIFF launched the under-19 league.[6] The inaugural season of the under-19 league would see East Bengal crowned champions.[6] Only three seasons of the under-19 league were held in 2001, 2002–03, and 2004–05.[6] The AIFF also fielded the India under-16 side in the league when held.[6]
In July 2003, East Bengal made history for the NFL when they won the 2003 ASEAN Club Championship, becoming the first Indian side to win an Asian level competition.[7] Prior to the 2006–07 season, the AIFF launched a third division, which was essentially just the qualifiers for the second division.[8] After the season concluded, the AIFF announced that the NFL would be disbanded and replaced with a new fully-professional league, the I-League for the 2007–08 season.[9]Dempo finished as the final NFL champions.[3]
