At the end of the tenth century Turks from Afghanistan began raiding India, a country of enormous wealth, ripe for conquest and incorporation into th… - Muhammad ibn Tughluq

One of the gravest charges against the sultan is that of compelling the inhabitants of Delhi to leave the town. The reason for this was that they used to write missives reviling and insulting him, seal them and inscribe them, “By the hand of the Master of the World, none but he may read this.” They then threw them into the audience-hall at night, and when the sultan broke the seal he found them full of insults and abuse. He decided to lay Delhi in ruins, and having bought from all the inhabitants their houses and dwellings and paid them the price of them, he commanded them to move to Dawlat Abad. They refused, and his herald was sent to proclaim that no person should remain in the city after three nights. The majority complied with the order, but some of them hid in the houses. The sultan ordered a search to be made for any persons remaining in the town, and his slaves found two men, in the streets, one a cripple and the other blind. They were brought before him and he gave orders that the cripple should be hung from a mangonel and the blind man dragged from Delhi to Dawlat Abad, a distance of forty days’ journey. He fell to pieces on the road and all of him that reached Dawlat Abad was his leg. When the sultan did this, every person left the town, abandoning furniture and possessions, and the city remained utterly deserted. A person in whom I have confidence told me that the sultan mounted one night to the roof of his palace and looked out over Delhi, where there was neither fire nor smoke nor lamp, and said “Now my mind is tranquil and my wrath appeased.” Afterwards he wrote to the inhabitants of the other cities commanding them to move to Delhi to repopulate it. The result was only to ruin their cities and leave Delhi still unpopulated, because of its immensity, for it is one of the greatest cities in the world. It was in this state that we found it on our arrival, empty and unpopulated, save for a few inhabitants.

Writing about the days of Sultan Muhammad bin Tughlaq (1325-51), Shihabuddin Al-Umari writes: “The Sultan never ceases to show the greatest zeal in making war upon the infidels… Every day thousands of slaves are sold at a very low price, so great is the number of prisoners… (that) the value at Delhi of a young slave girl, for domestic service, does not exceed eight tankahs. Those who are deemed fit to fill the parts of domestic and concubine sell for about fifteen tankahs. In other cities prices are still lower…” Probably it was so because Ibn Battuta while in Bengal says that a pretty Kaniz (slave girl) could be had there for one gold dinar (or 10 silver tankahs). “I purchased at this price a very beautiful slave girl whose name was Ashura. A friend of mine also bought a young slave named Lulu for two gold coins.”32...Umari continues, “but still, in spite of low price of slaves, 20000 tankahs, and even more, are paid for young Indian girls. I inquired the reason… and was told that these young girls are remarkable for their beauty, and the grace of their manners.”

Ulugh Khan destroyed the great Svayambhusiva temple, whose fragments remain scattered around Warangal’s fort area. He built an enormous mosque on the site of the temple, along with a huge audience hall... By the time Ulugh Khan ascended the throne, considerable parts of the Deccan and south India had acknowledged the suzerainty of Delhi.
