After the death of Muhammad of Ghor, Qutbuddin Aybak (his Commander-in-chief) established rule in CE 1206 with Delhi as the seat of power. This dynasty is known as the Mamluk dynasty (Slave Dynasty).
Four major dynasties ruled Delhi after the decline of the Mamluk dynasty and their rule lasted until CE 1526. The rulers of Delhi between CE 1206 and CE 1526 are known as Sultans and the period of their reign known as the Sultanate period.
