Shams ud-Din Kayumars (Persian: شمس الدین کیومرث), also known by his regnal name, Shamsuddin II[1] (Persian: شمس الدین دوم; c. 1285 – 13 June 1290, reigned in 1290) was a son of Muiz ud-Din Qaiqabad, the eleventh sultan of the Mamluk dynasty of the Delhi Sultanate.
His father Muiz ud din Qaiqabad is said to have been murdered by a Khalji noble, Jalal ud-Din Firuz Khalji. Khalji assumed the throne after murdering Kayumars, ending the Mamluk dynasty and starting the Khalji dynasty.[2] By that time Qaiqabad was struck down with paralysis and the Turkic nobles had raised his three-year-old son Kayumars to the throne as the Sultan.
