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.
Indian Super League
In July 2017, it was proposed by the All India Football Federation (AIFF) that the Indian Super League champion be granted a spot in the AFC Cup, Asia's second-tier club competition. On 25 July 2017, the Asian Football Confederation (AFC) approved the AIFF's proposal. Thus, from the 2017–18 season, the Indian Super League champions were allowed to participate in the AFC Cup from the qualification stages of the competition. Meanwhile, India's spot in the AFC Champions League, Asia's top club competition, was still kept by the I-League.
