[2] The foundation of Mohun Bagan stretches back into the 1880s when the neighborhood youth of presently known Fariapukur Lane in Shyambazar had set out in search for an ideal place to establish a football club, and came across a marble palace, Mohun Bagan Villa, owned by the family of a leading jute trader, Kirti Chandra Mitra.

[3][7] The club management hugely emphasized providing memberships to the youth and maintained a strict code of conduct with an avowed objective of producing excellent sportsmen and imbuing them with impeccable moral and social values.

[3] At the first-anniversary assembly, the Presidency College students and members of the club invited their professor, F. J. Rowe, to attend.

[7] The club ground was later relocated to Shyam Square in Bagbazar, with the help of the Kolkata Municipal Corporation chairman, Henry Lee.

The registered members forms the Mohun Bagan Society, which takes part in the general elections for the appointment for various posts.

[12] In past many big names like Sourav Ganguly, Sachin Tendulkar, Virat Kohli, MS Dhoni and even Sri Lankan player Chaminda Vaas had played for the club.

The team plays its home matches mostly at the SAI Sports Complex of Salt Lake Stadium and also at the Mohun Bagan Ground.

[16] Mohun Bagan also took part in the inaugural season of e-ISL where the ISL teams competed to play the video game FIFA 22.

Since 2001, 29 July is celebrated as Mohun Bagan Day in honor of the club's victory over East Yorkshire Regiment in the 1911 IFA Shield Final.
