The Muslim invasions into India had ultimately resulted in the establishment of Delhi Sultanate which existed from A.D. 1206 to 1526. Five different dynasties  the Slave, Khalji, Tughlaq, Sayyids and Lodis  ruled under the Delhi Sultanate. Not only they extended their rule over North India, but also they penetrated into the Deccan and South India. Their rule in India resulted in far-reaching changes in society, administration and cultural life.

Slave Dynasty

The Slave dynasty was also called Mamluk dynasty. Mamluk was the Quranic term for slave. The Slave dynasty ruled Delhi from A.D. 1206 to 1290. In fact, three dynasties were established during this period. They were

1. Qutbi dynasty (1206-1211) founded by Qutbuddin Aibak.

2. First Ilbari dynasty (1211- 1266) founded by Iltutmish.

3. Second Ilbari dynasty (1266-1290) founded by Balban.

Qutbuddin Aibak (1206-1210)

Qutbuddin Aibak was a slave of Muhammad Ghori, who made him the Governor of his Indian possessions. He set up his military headquarters at Indraprasta, near Delhi. He raised a standing army and established his hold over north India even during the life time of Ghori. After the death of Ghori in 1206, Aibak declared his independence. He severed all connections with the kingdom of Ghori and thus founded the Slave dynasty as well as the Delhi Sultanate. He assumed the title Sultan and made Lahore his capital. His rule lasted for a short period of four years. Muslim writers call Aibak Lakh Baksh or giver of lakhs because he gave liberal donations to them. Aibak patronized the great scholar Hasan Nizami. He also started the construction of after the name of a famous Sufi saint Khwaja Qutbuddin Bakthiyar. It was later completed by Iltutmish. Aibak died suddenly while playing chaugan (horse polo) in 1210. He was succeeded by his son Aram Baksh, who was replaced by Iltutmish after eight months.
