"The population was very much greater (on the eve of Turkish invasions) than at the death of Akbar. During centuries of invasions, constant oppression and misrule, the wholesale massacres during the Pathan period, the population of India dwindled...This broad fact emerges from the two estimates (Ferishtah’s and Moreland’s), howsoever erroneous or full of fallacies the individual estimates may be."
