Kayumars (1290) was the son of Muiz ud din Qaiqabad (1286–1290), who was the tenth sultan of Mamluk dynasty (Slave dynasty). He was declared ruler at the age of three, once his father had suffered from a paralytic stroke and later murdered by a Khilji chief. However, Kayumars' guardian, Jalal ud din Firuz Khilji, eventually dethroned Kayumars and declared himself king, thus bringing an end to the Mamluk dynasty of Delhi.
