He carried out some important reforms

One of the most interesting facts about Alauddin Khilji is marked by his comprehensive reforms. Despite the criticisms that Alauddin was a barbarian, he was successful in implementing important military and agricultural improvements for the country. The agrarian economy of the kingdom was based on the peasant and farmer communities, therefore this was especially beneficial to them. He also changed the tax system, essentially freeing the farmers from the control of the Zamindars, who serve as their landlords. He also decided to outlaw gambling, drinking, and using drugs.

Alauddin implemented extensive reforms, in contrast to the previous Delhi Sultanate rulers who had mostly depended on the pre-existing administrative structure. He adopted various reforms to be able to maintain a sizable army and to weaken those capable of staging a revolt against him after dealing with the Mongol invasions and several uprisings.

For a wide range of market items, Alauddin employed price control mechanisms. Alauddin hired market watchers and spies and got unbiased reports from them to make sure the commodities were sold at set pricing. His administration built government-run granaries where the government's part of the grain was stored in order to prevent the development of a black market. Peasants and traders were also forbidden from storing the grains there. In order to facilitate the quick transportation of grain to Delhi, the government also required the transport workers to relocate to villages along the Yamuna river at particular distances.
