The new club established on 1st August 1920 was christened East Bengal as the founders hailed from that region of Bengal.
Incidentally Manmatha Nath Chaudhuri was the Maharaja of Santosh, now in Bangladesh, after whom the Santosh Trophy is titled.
Thereafter the founders debated intensely over the choice of colours for the club jersey. After a long search they opted for a red and golden colour shirt hanging impressively at the Whiteaway, Laidlaw & Co. Departmental Store at Chowringhee. These colours became permanently associated with the club.
The club played its maiden tournament in the same month of its establishment i.e. August 1920. The tourney was Hercules Cup, a seven-a-side competition that the club won without any Herculean effort.
The club set up its first managing committee with Prof. Sarada Ranjan Roy, Principal of Vidyasagar College who assumed the post of the President.
East Bengal never looked back after that. It did not believe in rising like a meteor, but dazzled like a sun in a blaze of glory, rewriting soccer history in the country over and over again.
