(i) Mamluk Sultans were rulers of the Slave dynasty. The Mamluk Sultans ruled from AD 1206 to 1290.

(ii) The credit of consolidating the Delhi Sultanate lies largely with Iltutmish.

(iii) Iltutmish took up the task of consolidating his position. He defeated Yaldoz in AD 1213 in the battle of Tarain. In AD 1217, he drove away Qabacha from Punjab.

(iv) In AD 1220, when Chenghiz Khan destroyed the Khwarezm empire, Iltutmish realised the political necessity of avoiding a confrontation with the Mongols. Thus, when Jalaluddin Mangbarane, while escaping from the Mongols, sought selter at Iltutmish's court, Iltutmish turned him away. He thus saved the Sultanate from destruction by the Mongols.

(v) From AD 1225 onwards, Iltutmish engaged his armies in suppressing the disturbances in the East. In AD 1226-27 he defeated Iwaz Khan and brought Bengal and Bihar back into the Delhi Sultanate.

(vi) He also launched similar campaigns against the Rajput chiefs. In AD 1226 he captured Ranthambore and in AD 1231 he established his authority over Mandor, Jalore, Bayana and Gwalior.

(vii) The Delhi Sultanate now covered a sizable territory. He also organised his trusted nobles or officers into a group of 'forty'.

(viii) Iltutmish effectively suppressed the defiant arms of Delhi. He separated the Delhi Sultanate from Ghazni, Colhar and Central Asian politics. Iltutmish also obtained a 'Letter of Investiture' in AD 1229 from the Abbasid Caliph of Baghdad to gain legitimacy.

Thus, Iltutmish adopted all the tactics to consolidate his position in the Delhi Sultanate.
