Why did the EIC become involved in the sub continent?

Traders reported evidence of immense wealth in the sub-Continent which led to the EIC establishing a trading base there since they saw a profitable future. It also wanted to establish its influence in the sub-Continent and to oust the Dutch and Portuguese. The EIC also wanted to establish a strategic port in the sub-continent that would protect its trading interests there.

There was no political motive at this stage.
