His favourite residence is said to have been the old capital of Ghazni, while he governed his Indian conquests through the agency of a favourite slave, Kutb-ud-din.
On the death of Mahommed Ghori, Kutb-ud-din at once laid aside the title of viceroy, and proclaimed himself sultan of Delhi.
The name of Kutb is preserved in the minar, or pillar of victory, which still stands amid the ruins of ancient Delhi, towering high above all later structures.
Kutb himself is said to have been successful as a general and an administrator, but none of his successors has left a mark in history.
These were - (1) the Adil Shahi dynasty, with its capital at Bijapur, founded in 1490 by a Turk; (2) the Kutb Shahi dynasty, with its capital at Golconda, founded in 1512 by a Turkoman adventurer; (3) the Nizam Shahi dynasty, with its capital at Ahmednagar, founded in 1490 by a Brahman renegade; (4) the Imad Shahi dynasty of Berar, with its capital at Ellichpur, founded in 1484 also by a Hindu from Vijayanagar; (5) the Barid Shahi dynasty, with its capital at Bidar, founded about 1492 by one who is variously described as a Turk and a Georgian slave.
In 1193 the city was captured by Kutb-ud-din.
But the invaders appear to have acquired only an imperfect possession of the country, as it was again wrested from the Hindu princes of Orissa about the year 1571, during the reign of Ibrahim, of the Kutb Shahi dynasty of Hyderabad or Golconda.
South of the modern city, amid the ruins of old Delhi, stands the Kutb Minar, which is supposed to be the most perfect tower in the world, and one of the seven architectural wonders of India.
It stands in the south-east corner of the outer court of the mosque erected by Kutb-ud-din immediately after his capture of Delhi in 1193.
Whatever its dim predecessors may have been, however, the actual history of Delhi dates no further back than the 11th century A.D., when Anangapala (Anang Pal), a chief of the Tomara clan, built the Red Fort, in which the Kutb DSinar now stands; in 1052 the same chief removed the famous Iron Pillar from its original position, probably at Muttra, and set it up among a group of temples of which the materials were afterwards used by the Mussulmans for the construction of the great Kutb Mosque.
Delhi became henceforth the capital of the Mahommedan Indian empire, Kutb-ud-din (the general and slave of Mahommed of Ghor) being left in command.
His dynasty is known as that of the slave kings, and it is to them that old Delhi owes its grandest remains, among them Kutb Mosque and the Kutb Minar.
His successor Feroz Shah Tughlak transferred the capital to a new town which he founded some miles off, on the north of the Kutb, and to which he gave his own name, Ferozabad.
