Alauddin Khalji was not only an able administrator but also an efficient expansionist. The steps taken by him to expand his kingdom have been discussed below.
He introduced the iqta system, It was a noble policy that helped him to maintain a strong army and make arrangements to pay the salary to his soldiers.
He took several steps to control the power of iqtadars. He strictly stated the limit of the soldiers that an iqtadar could maintain. He also saw to it that the muqtis were frequently transferred and the seats did not become hereditary. To avoid the iqtadars from gaining too much power, he made sure they collected only the revenue and no other self-imposed tax.
The army was also an important instrument for expansion. To maintain a strong army, the prices of commodities were regulated. Few soldiers were also given the salary in cash.
