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.
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.
