"But though India was never thoroughly subdued by the sword of Islam, and though the country only became partially Mahomedan, yet the whole framework of her institutions was shaken and dislocated by incessant resistance. The Mahomedans disorganized Hinduism without substituting any strong religious edifice of their own, as they managed to do elsewhere. The military adventurers, who founded dynasties in Northern India and carved out kingdoms in the Deklian, cared little for things spiritual; most of them had, indeed, no time for proselytism, being continually engaged in conquest or in civil war."
