The medieval period of Indian history has been a source of propaganda for historians with ideological predilections. .... But the tradition of tailoring and embroidering the past for influencing the course of future developments did not die with the departure of the British. The burden of carrying forward this admittedly unscientific historiography has now been enthusiastically assumed by their Marxist prototypes. Being victims of ideological myopia, the Marxist historians of India have cared to see only that aspect of reality which falls within the range of their narrow vision. Those aspects of reality which fall beyond it have been either left unexplained or treated merely as an extension of that which they have perceived and, therefore, utterly unworthy of their serious attention.

Of quite a few casualties of the standards of academic integrity at the hands of self-styled 'secular' academics, those in the field of medieval Indian historiography happen to be the worst.

Professor D.P.Singhal asserts that, contrary to the general belief, Indians in ancient times did not neglect the important discipline of historiography. On the contrary, they were good writers of history. He states: “Ancient India did not produce a Thucydides, but there is considerable evidence to suggest that every important Hindu court maintained archives and geneologies of its rulers. And Kalhana’s Rajatarangini, written in twelfth century Kashmir, is a remarkable piece of historical literature. Despite his lapses into myths and legends, Kalhana had an unbiased approach to historical facts and history writing. He held that a true historian, while recounting the events of the past, must discard love (raga) and hatred (dvesha). Indeed, his well-developed concept of history and the technique of historical investigation have given rise to some speculation that there existed at the time a powerful tradition of historiography in which Kalhana must have received his training.”
