Alauddin Khilji's primary motivation for introducing strict price controls and market regulations was military. He needed to maintain a large and efficient standing army to face the Mongol invasions and expand his empire. A large army was expensive. By fixing low prices for essential commodities, especially food grains, he ensured that his soldiers, who were paid a relatively low salary in cash, could afford to live comfortably and were not tempted by disaffection or looting due to economic hardship.
