One of his slaves named Kutb-ud-Din Ibak became his general and viceroy and, when Muhammad died, founded at Delhi the dynasty known as Slave Sultans. Muhammad Adil, the second of this line, attempted to move the capital from Delhi to Daulatabad in the Deccan. In 1398 northern India was convulsed by the invasion of Timur who only remained a few months but sacked Delhi with terrible carnage.

The two chiefs then induced other Rajahs of the Malabar and Kanara countries to join them, and the joint forces seized the whole of the Dakhan and expelled the Muhammadans there, "so that within a few months Muhammad Taghlak had no possessions in that quarter except Daulatabad." So far the Muhammadan historian.

The attempt to bring into the imperial scheme the Deccan provinces south of the Vindhyan range, followed the next year, and continued for eight years later. On the whole it was successful. The strong places, Daulatábád, Kherwá, Násik, Asírgarh, and Ahmadnagar, opened their gates, after long sieges, to the imperial arms.

There were campaigns also against the Hindus of Rajahmundry, Vinukonda, and other places, and in 1472 one against Belgaum, which has been already described. Firishtah tells us that the Daulatabad and Junir troops were sent against the powerful Hindu Raja Narasimha on the east coast. As to Kulbarga and his experiences there, Nikitin writes as follows: "The Hindus ... are all naked and bare-footed.

The Ballala prince consented, and Krishna Naik promised, when the preparations were complete, to raise all the Hindus of Telingana and place himself at their head. Ballala Deva then built the city of Vijayanagar, raised an army, and the war began. Warangal, then in the hands of the Muhammadans, was reduced, and its governor, Imad-ul-Mulkh, retreated to Daulatabad or Devagiri.

Upon this they all went out; but his servants finding a blind man in one of the houses and a bedridden one in the other, the Emperor commanded the bedridden man to be projected from a balista, and the blind one to be dragged by his feet to Daulatabad, which is at the distance of ten days, and he was so dragged; but his limbs dropping off by the way, only one of his legs was brought to the place intended, and was then thrown into it; for the order had been that they should go to this place.
