The Mamluk dynasty, also known as Slave dynasty, was a dynasty which ruled Delhi Sultanate from 1206 to 1290. It was the first of five largely unrelated dynasties to rule the Delhi Sultanate until 1526. Before the establishment of the Mamluk dynasty, Qutb al-Din Aibak's tenure as a Ghurid dynasty administrator lasted from 1192 to 1206, a period during which he led forays into the Gangetic plain and established control over some of the new areas.

The Delhi Sultanate or the Sultanate of Delhi was a late medieval empire primarily based in Delhi that stretched over large parts of the Indian subcontinent, for 320 years (1206–1526). Following the invasion of South Asia by the Ghurid dynasty, five dynasties ruled over the Delhi Sultanate sequentially: the Mamluk dynasty (1206–1290), the Khalji dynasty (1290–1320), the Tughlaq dynasty (1320–1414), the Sayyid dynasty (1414–1451), and the Lodi dynasty (1451–1526). It covered large swaths of territory in modern-day India, Pakistan, and Bangladesh as well as some parts of southern Nepal.
