The Delhi Sultanate is a term used to cover five short-lived dynasties, Delhi based kingdoms or sultanates, mostly of Turkic and Pashtun (Afghan) origin in medieval India. The sultanates ruled from Delhi between 1206 and 1526, when the last was replaced by the Mughal dynasty. The five dynasties were the Mamluk dynasty (1206–90); the Khilji dynasty (1290–1320); the Tughlaq dynasty (1320–1414); the Sayyid
dynasty (1414–51); and the Afghan Lodi dynasty (1451–1526). The Mamluk Dynasty or Slave Dynasty, directed into India by Qutb-ud-din Aibak, a Turkish general of Central Asian birth, was the first of five unrelated dynasties to rule India’s Delhi Sultanate from 1206 to 1290.
