The Mamluk dynasty (Persian: سلطنت مملوک, romanized: Salṭanat Mamlūk), also known as Slave dynasty, was a dynasty which ruled the Delhi Sultanate from 1206 to 1290. It was the first of five largely unrelated dynasties to rule the Delhi Sultanate until 1526.[9][10][11] 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.[12][13]

^Note: other sources describe the use of two flags: the black Abbasid flag, and the red Ghurid flag, as well as various banners with figures of the new moon, a dragon or a lion. "Large banners were carried with the army. In the beginning the sultans had only two colours : on the right were black flags, of Abbasid colour; and on the left they carried their own colour, red, which was derived from Ghor. Qutb-u'd-din Aibak's standards bore the figures of the new moon, a dragon or a lion; Firuz Shah's flags also displayed a dragon." in Qurashi, Ishtiyaq Hussian (1942).
