The introduction of paying salaries in cash to the soldiers led to price regulations popularly called as Market Reforms. Alauddin Khalji established four separate markets in Delhi, one for grain; another for cloth, sugar, dried fruits, butter and oil; a third for horses, slaves and cattle; and a fourth for miscellaneous commodities. Each market was under the control of a high officer called Shahna-i- Mandi. The supply of grain was ensured by holding stocks in government store-houses. Regulations were issued to fix the price of all commodities. A separate department called Diwani Riyasat was created under an officer called Naib-i-Riyasat. Every merchant was registered under the Market department. There were secret agents called munhiyans who sent reports to the Sultan regarding the functioning of these markets. The Sultan also sent slave boys to buy various commodities to check prices. Violation of regulations was severely punished. Harsh punishment was given if any shop- keeper charged a higher price, or tried to cheat by using false weights and measures. Even during the famine the same price was maintained. We are not sure whether the market regulations in Delhi were also applied in the provincial capitals and towns.

Apart from market reforms, Alauddin Khalji took important steps in the land revenue administration. He was the first Sultan of Delhi who ordered for the measurement of land. Even the big landlords could not escape from paying land tax. Land revenue was collected in cash in order to enable the Sultan to pay the soldiers in cash. His land revenue reforms provided a basis for the future reforms of Sher Shah and Akbar.

Military Campaigns

Alauddin Khalji sent his army six times against the Mongols. The first two was successful. But the third Mongol invader Khwaja came up to Delhi but they were prevented from entering into the capital city. The next three Mongol invasions were also dealt with severely. Thousands of Mongols were killed. The northwestern frontier was fortified and Gazi Malik was appointed to as the Warden of Marches to protect the frontier.
