How did the misinterpretation of the Indian history by the British historians cause communalism in India?

The British divided the Indian history into Hindu and the Muslim periods. In the Hindu period, they dubbed the Muslims as foreign invaders who settled here as conquerors. In the Muslim period, they identified the Muslims as rulers and the Hindus as a subjugated people. By exposing and playing aloud the atrocities committed by individual rulers, the English historians tried to create hatred among the Hindus against the Muslims and the Muslims against the Hindus. All this created a rift between the two communities.
