The subcontinent of South Asia has inexorably been developing into a cauldron of violence ever since the origins of Islam in Arabia and its steady expansion to the east. Here it clashed with Hinduism a religion that was an antithesis of Islam and over the centuries this unhappy mix has been smoldering and has now reached a point where there is likely to be a furious conflagration. During the course of the history of this subcontinent there have been many watersheds, ever since the advent of Islam into this region. The first serious clashes took place in the hot plains of North India when the Muslim armies clashed with the Hindu Rajput rulers. After some fierce battles, the Hindu peoples settled under the kings of the Muslim Sultanates of the earlier dynasties of the Slave kings, until the Mughals stabilized a Caliphate in North India. The Mughals after Aurangzeb declined and the dynasty petered out.
