It is related that his army consists of 900,000 horsemen, a part of them are at His Majesty’s court, others are scattered in the whole country. His D… - Muhammad ibn Tughluq

The Sultan who is ruling at present has achieved that which had not been achieved so far by any king. He has achieved victory, supremacy, conquest of countries, destruction of the forts of the infidels, and exposure of magicians. He has destroyed idols by which the people of Hindustan were deceived in vain.

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.

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.
