Asia's oldest football league began by shutting Indian clubs out entirely
For its first fifteen seasons the Calcutta Football League admitted British army sides, merchants and missionaries but no Indian clubs at all. When Mohun Bagan and Aryan were finally let in in 1914, a quota still capped native teams at two per division, and it took East Bengal's protest a decade later to scrap it.
The Indian Football Association launched the league in 1898 as a two-tier competition modelled on England's Football League, which makes it the oldest in Asia. Teams from the garrison at Fort William dominated, taking every title up to 1933 except twelve, which went to the civilian clubs Calcutta and Dalhousie. Indian sides stayed barred until 1914, and even afterwards winners such as Kumortuli Club, champions of the Second Division three years running from 1917, were refused promotion because of the limit on native teams.
East Bengal joined the lower tier in 1921 and shared the Second Division title three years later. Facing rejection under the quota, the club pushed for a rule change; the nine British teams voted in favour while Mohun Bagan and Aryan, the two Indian clubs already in the top flight, voted against, and the cap was abolished by majority. British sides kept winning until 1934, when Mohammedan took the title in its first season, the first Indian club to do so. It then won six of the next seven, skipping only 1939, when Mohun Bagan claimed its first championship.
After independence, monsoon-season derbies between the Big Three of Mohun Bagan, East Bengal and Mohammedan often drew over 30,000 people. Rivalry between supporters turned deadly on 16 August 1980, when 16 fans died in a stampede and rioting at Eden Gardens; the date is now marked as Football Lover's Day. National leagues gradually drew the best clubs away, and from 1982 only East Bengal or Mohun Bagan won the title. East Bengal took a record eight straight titles from 2010 until Mohun Bagan ended the run in 2018.
Peerless broke the duopoly in 2019, the first outsider to win since Eastern Railway in 1958. Today the league is a seven-tier pyramid of more than 160 clubs and over 8,500 registered players. The 2020 season was cancelled because of COVID-19, the first cancellation since independence.
