Qutbuddin Aibak's conquests (c. 1200-10) included Gwalior, parts of Bundelkhand, Ajmer, Ranthambhor, Anhilwara as well as parts of U. P. and Malwa. In Naharwala alone 50,000 persons were killed during Aibak's campaign. No wonder that besides earning the honorific of lakhbakhsh (giver of Lakhs) he also earned the nickname of killer of lakhs.
