Dividing the history of a country on the basis of religion of the rulers is unacceptable, as it completely overlooks other important driving forces of history. These forces could be economic such as the beginning of feudalism or social such as the beginning of the caste system. Few narrow-minded British historians divided the Indian history into three periods: Hindu, Muslim and British. British historians who dominated the historiography in the 19th and 20th centuries completely overlooked other important aspects of history in India and believed that there were no other significant developments except the religion of the governing authority. It was mainly a way to implement the divide and rule policy of the British in India.
