Mongol invasion posed a big administrative challenge for the Delhi Sultanate. Accordingly, the Delhi Sultanate mobilised a large standing army in Delhi. Further Alauddin Khalji constructed a new garrison town at Siri for his soldiers. He imposed taxes on land to feed the army at the rate of 50 per cent of peasant's yield. He began to pay the soldiers in cash. Muhammad Tughluq shifted people of Delhi to Daulatabad in South. He also raised a large standing army.

The following steps were taken to ensure that muqtis performed their duties
(i) Accountants were appointed by the state to check the amount of revenue collected by the Muqtis.
(ii) Care was taken that the Muqti collected only the taxes prescribed by the State and that he kept the required number of soldiers. Muqtis may have wanted to defy the orders of the Sultans as there were harsh conditions of service which rigorously imposed on them. Besides this, their office was not inheritable and sometimes they were assigned iqtas for a short time span and shifted regularly.
