#5 Mariners are accused of being slaves of the British
In the year 1924, East Bengal were jointly tied at the top spot of the CFL: 2nd Division along with Cameroons B, but as Cameroons A were already playing in the First Division, East Bengal were promoted. The process wasn't smooth as the IFA's Governing Body rules permitted only two Indian teams to play in the elite division and the quotas were already occupied by Mohun Bagan and Aryans. It called for a change of rules and in the following Governing Body meeting, those who opposed the club's promotion were ironically the Indian teams, Mohun Bagan and Aryans.
The remaining nine British clubs conveyed their approval. Majority prevailed and East Bengal embarked upon their campaign in the Premier Division.
Mohun Bagan were believed to favour the dominance of British clubs in the Premier Division at a time when revolutionists were in constant battle with the British to gain Independence. Due to this incident, East Bengal fans detest the Mariners by calling them 'Slaves of the British'.
