There have been numerous attempts to explain the fall of the Mughal Empire; and I truly feel great hesitation in adding myself to the long list of its exponents. To historians like Irvine and Sarkar, the decline could be explained in terms of a personal deterioration in the quality of the kings and their nobles. The harem influence grew—and women, for some strange unscientific reason, are always supposed to be a bad influence. The kings and nobles became more luxury loving, though no-one has yet established that the Mughals during the sixteenth and seventeenth centuries enjoyed any less luxurious mode of living than their eighteenth-century successors. Sarkar, in his monumental History of Aurangzib, also elaborated upon the traditionally recognized factor, namely, Hindu–Muslim differences: Aurangzib's religious policy is thought to have provoked a Hindu Reaction that undid the unity that had been so laboriously built up by his predecessors.
