Muhammad bin Tughluq, the Sultan of Delhi, made significant contributions to the city, leaving a lasting impact on its history.


Muhammad bin Tughluq decided to shift the capital from Delhi to Daulatabad in the Deccan region. This decision was driven by his desire to have a centralized administration and to control the southern territories effectively. However, the shifting of the capital resulted in several challenges, including logistical difficulties, economic burden, and increased taxes on the common people. Eventually, the capital was moved back to Delhi due to these challenges.


Another significant contribution of Muhammad bin Tughluq was the introduction of token currency. He introduced copper coins that had the same value as silver coins. This move was aimed at solving the scarcity of silver coins and facilitating trade. However, the implementation of token currency was met with resistance and confusion among the people, causing economic instability.


Alauddin Khilji, a powerful ruler of the Delhi Sultanate, made notable contributions to the city of Delhi during his reign.


Alauddin Khilji implemented several reforms in the revenue system to ensure a stable economy. He introduced the 'measurement of produce' system, where crops were measured and taxed accordingly. This helped in reducing corruption and ensuring a fair assessment of taxes. Additionally, he established market control measures to regulate prices and prevent hoarding.


Alauddin Khilji strengthened the military infrastructure of Delhi by introducing a new force known as the 'New Garrison' or 'Chahalgani.' This force consisted of 40,000 cavalrymen who were paid regular salaries. These military reforms helped in maintaining law and order, protecting the kingdom, and expanding the empire's boundaries.

Overall, the contributions of Muhammad bin Tughluq and Alauddin Khilji played a significant role in shaping the history and fame of Delhi. While Muhammad bin Tughluq's decisions had mixed results, Alauddin Khilji's reforms contributed to the stability and growth of the city.
