Explanation:

The Delhi Sultanate was an Islamic empire based in Delhi that stretched over large parts of the Indian subcontinent for 320 years (1206–1526). Five dynasties ruled over the Delhi Sultanate sequentially: the Mamluk dynasty (1206–1290), the Khilji dynasty (1290–1320), the Tughlaq dynasty (1320–1414), the Sayyid dynasty (1414–1451), and the Lodi dynasty (1451–1526). Qutb al-Din Aibak, a former Turkic Mamluk slave of Muhammad Ghori, was the founder of the Delhi Sultnate, and his Mamluk dynasty conquered large areas of northern India. Afterwards, the victories of the Khilji dynasty expanded in the south. The sultanate reached the peak of its geographical reach during the Tughlaq dynasty, occupying most of the Indian subcontinent.
