Alauddin had 50,000 slaves some of whom worn mere boys,* and surely many captured during wax. Firoz Tughlaq had issued an order that whichever places… - K. S. Lal

In medieval India Muslim ruling classes drank freely, at the same time punishing poor helpless Muslims for the "crime". For example, while Alauddin Khalji had prohibited wine-drinking, his own son Qutbuddin Mubarak drank hard and so drank his nobles. All Mughal emperors from Babur to Shahjahan drank hard, Jahangir drank the hardest. But since wine is prohibited in Islam, it was a matter of routine for rulers to put a stop to drinking by common people. Even orthodox sultans like Firoz Tughlaq and Sikandar Lodi drank secretly "to keep in good health". Most of the Mughal nobles drank openly and "all princes drank in secret."

The chroniclers of the early Turkish rulers of India take pride in affirming that Qutbuddin Aibak was a killer of lakhs of infidels. Leave aside enthusiastic killers like Alauddin Khalji and Muhammad bin Tughlaq, even the "kind-hearted" Firoz Tughlaq killed more than a lakh Bengalis when he invaded their country. Timur Lang or Tamerlane says he killed a hundred thousand infidel prisoners of war in Delhi. He built victory pillars from severed heads at many places. These were acts of sultans. The nobles were not lagging behind. One Shaikh Daud Kambu is said to have killed 20,000 with his dagger. The Bahmani sultans of Gulbarga and Bidar considered it meritorious to kill a hundred thousand Hindu men, women and children every year. .... The rite of Jauhar killed the women, the tradition of not deserting the field of battle made Rajputs and others die fighting in large numbers. When Malwa was attacked (1305), its Raja is said to have possessed 40,000 horse and 100,000 foot.43 After the battle, "so far as human eye could see, the ground was muddy with blood". ...Under Muhammad Tughlaq, wars and rebellions knew no end. His expeditions to Bengal, Sindh and the Deccan, as well as ruthless suppression of twenty-two rebellions, meant only depopulation in the thirteenth and first half of the fourteenth century. For one thing, in spite of constant efforts no addition of territory could be made by Turkish rulers from 1210 to 1296; for another the Turkish rulers were more ruthless in war and less merciful in peace. Hence the extirpating massacres of Balban, and the repeated attacks by others on regions already devastated but not completely subdued..... Mulla Daud of Bidar vividly describes the war between Muhammad Shah Bahmani and the Vijayanagar King in 1366 in which "Farishtah computes the victims on the Hindu side alone as numbering no less than half a million." Muhammad also devastated the Karnatak region with vengeance..... Under Akbar and Jahangir "five or six hundred thousand human beings were killed," says emperor Jahangir. The figures given by these killers and their chroniclers may be a few thousand less or a few thousand more, but what bred this ambition of cutting down human beings without compunction was the Muslim theory, practice and spirit of Jihad, as spelled out in Muslim scriptures and rules of administration.

Population studies of pre-census times are being successfully attempted in many western countries but in India not much work has been done in this area. This book is almost: a maiden attempt at population study the medieval period. ... Besides, any study of population of pre-census times can be based only on estimates and estimates by their very nature tend to be tentative. In our computation, however, sufficient historical evidence has been forthcoming for any demographic behaviour. If nothing more. I have at least been able to collect in one place direct and indirect evidence leading to fairly good estimates of medieval Indian population, although the estimates themselves may not always be invulnerable to challenge. However I hope that the uniqueness, magnitude and delicacy of the task would make the reader indulgent and the critic tolerant.
