Explanations:The Delhi Sultanate was a significant period in Indian history, marked by the rule of various dynasties, including the Khilji, Tughlaq, and Mamluk dynasties. Each ruler implemented various policies to consolidate their power and manage the economy of their vast empires. One of the most notable rulers in terms of economic reforms was Muhammad bin Tughlaq, who ruled from 1325 to 1351 CE.
Muhammad bin Tughlaq was known for his ambitious and often controversial economic policies. One of his significant actions was the revival of taxation in the Doab region, which is the fertile land between the Ganges and Yamuna rivers. The Doab region was crucial for agriculture and trade, and its taxation was a vital source of revenue for the Delhi Sultanate. Muhammad bin Tughlaq also levied additional taxes to support his ambitious projects and military campaigns.
The Doab region was particularly important because it was a breadbasket of the Delhi Sultanate, providing substantial agricultural produce and revenue. By reviving the taxation of this region and introducing additional taxes, Muhammad bin Tughlaq aimed to increase the state's revenue and fund his various projects. However, these policies were often met with resistance from the local population, leading to social unrest and economic difficulties.
It is essential to understand the historical context of the Delhi Sultanate and the economic policies of its rulers to appreciate the significance of Muhammad bin Tughlaq's actions. While other rulers like Alauddin Khilji, Nasiruddin Muhammad Tughlaq, and Ghiyasuddin Balban also implemented economic reforms, they did not specifically focus on the revival of taxation in the Doab region and the introduction of additional taxes as Muhammad bin Tughlaq did.
Therefore, the correct answer is Muhammad bin Tughlaq, as he is the ruler who revived the taxation of the Doab region and levied additional taxes, which were significant economic policies of his reign.
