Describe the impact of mongol invasion …

Mongol attacks on the Delhi Sultanate increased during the reign of Alauddin Khaiji and in the early years of Muhammad Tughluq's rule. Hence, a vast standing army was established under these two rulers to confront Mongol invasions. Alauddin constructed a new garrison town named Siri for his soldiers. He also started paying them salaries in cash rather than iqtas. He controlled the prices of goods in Delhi. Muhammad Tughluq also paid his soldiers cash salaries. But instead of controlling prices, he used a 'token7 currency, made out of cheap metals. He did so in order- to mobilise resources to fight Mongol army. Alauddin also made his administrative system very effective. Hence, he successfully withstood the threat of Mongol invasions. But Muhammad's administrative measures were a failure. He planned to attack the Mongol capital named Transoxiana. But soon he gave up it. His administrative measures created complications. The shifting of people to Dautabad was resented.
