Why was the state of the many, diverse, religions in india under british rule?

Britain needed more resources and more markets for selling their refined goods to, so they needed to expand their power. India was incredibly rich in both resources and in consumer markets, and was referred to by the British later on as, "The Crown in the British Empire", and with good reason. So, with superior weaponry, the British were able to take control of India. The result of it was the British sucking India of their resources for free, making goods out of them, and then selling them back to the Indian people at a price. 

An attractive economy.
