Mamluk dynasty, (1206–90), line of sultans of the Muiʿzzī family at Delhi, India, that lasted for nearly a century. It was the first of the Delhi sultanate dynasties and had no connection to the Mamluk rulers of Egypt and Syria.
The Mamluk dynasty was founded by Quṭb al-Dīn Aibak, a Mamluk (enslaved soldier) of the Muslim general and later sultan Muḥammad of Ghūr. Quṭb al-Dīn had been among Muḥammad’s most trusted Turkic army officers and had overseen his master’s conquests in India. When Muḥammad was assassinated in 1206, Quṭb took power in Lahore. He managed to consolidate his position in a seesawing war with a rival Mamluk ruler, Tāj al-Dīn Yildoiz, during which he captured and lost Ghazna. His sovereignty was eventually confined to India. He died in 1210 as a result of a polo accident, and the crown shortly passed to Iltutmish, his son-in-law.
By the time of Iltutmish’s accession, the family’s holdings had been severely reduced. Iltutmish, the most prominent in the Mamluk succession, defeated and put to death Yildoiz (1216), restored the Bengal governor to obedience, and added considerable new territory to the empire, including the Lower Sindh.
After the death of Iltutmish, his able daughter Raziyya attempted to serve as sultan but was defeated by opposing Turkic Mamluk nobles. After 1246 the sultanate was controlled by Ghiyās al-Dīn Balban, who was to be sultan himself from 1266 to 1287. Under Balban the Delhi sultanate fought off several Mongol invasions. The Mamluk dynasty ended when Jalāl al-Dīn Fīrūz Khaljī staged a successful coup against the sultan Kay-Qubādh on June 13, 1290, and brought the Khaljīs to power.
