Shams-ud-din Iltutmish (1210-36) of Turkish extraction was a slave of Qutbud-din Aibak. Many of his elite slaves were also of Turkish and Mongol ancestry.  

• They were brought to Delhi by merchants from trade centres like Bukhara, Samarqand and Baghdad. (There were some slaves of other ethnicities as well).  

• But Iltutmish gave them all Turkish titles. Iltutmish’s reliance on his elite military slaves (Bandagan) and his practice of appointing them for the posts of governors and generals in far-off places did not change despite the migration into North India of experienced military commanders from distinguished lineages fleeing from the Mongols.
