The Slave Dynasty (1206 – 1290 A.D.)

After the death of Muhammad Ghori in 1206 A.D. his slave Qutub-ud-din Aibak founded this dynasty. He extended the Muslim empire in many parts of the northern India. Due to his generosity, he came to be known as lakh-baksh – giver of lakhs. After his death Iltutmish became his successor. Delhi Sultanate was established during the reign of Iltutmish. He made Delhi as his capital. He made many conquests and ruled over whole of the northern India. On his deathbed he nominated his daughter Razia Sultana as successor. She was followed by Bahram Shah, Ala-ud-din Masud Shah, Naisr-ud-din Muhammad. Although Nasir-ud-din Muhammad ruled for twenty years but the main power remained in the hands of Ghiyas-ud-din Balban – one of the slaves of Iltutmish his original name was Baha-ud-din. Balban defended his empire from Mangol invation. After the death of Balban, all his successors became inefficient and weak hence, the Slave dynasty came to an end.
