In 1202, Aibak besieged Kalinjar, an important fort in the Chandela kingdom of central India. The Chandela ruler Paramardi initiated negotiations with Aibak, but died before a treaty could be finalized. The Chandela chief minister Ajayadeva resumed hostilities, but was forced to seek negotiations when the Ghurids cut off the water supply to the fort. As part of the truce, the Chandelas were forced to move to Ajaigarh. Their former strongholds of Kalinjar, Mahoba, and Khajuraho came under Ghurid control, governed by Hasan Arnal.
