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.

Muhammad Tughluq introduced many significant changes in his administrative system. In spite of all these changes his regime was a failure.
His major administrative failures were
(i) He campaigned into Kashmir but it proved a disastrous campaign. He then gave up plans to attack Transoxiana and disbanded his large army.
(ii) He shifted the residents of the old city to Daulatabad in the South. They resented collectively due to this.
(iii) In order to meet the expense of maintaining a large number of soldiers, levied additional taxes which increased the burden of the common man.
(iv) The famine in the Ganga-Yamuna belt led to widespread rebellion.
(v) People did not trust the token currency that was launched by Sultan. They saved their gold and silver coins and paid all their taxes to the state with the token currency. This cheap currency could also be counterfeited easily.
