Today, there are over 500 million Muslims throughout the Indian subcontinent (India, Pakistan, and Bangladesh), making it one of the largest population centers of Muslims in the world. Since Islam first entered India, it has contributed greatly to the area and its people. Today, numerous theories about how India came to be such a largely Muslim land exist. Politically, some (such as the Hindutva movement in India) try to make Islam seem foriegn to India, by insisting it only exists because of invasions by Arab and Persian Muslims. The truth, however, is far from that.
