Firoz Shah Tughlaq's Irrigation Contribution

Firoz Shah Tughlaq, a ruler of the Tughlaq dynasty in the Delhi Sultanate, made significant contributions to public works, particularly focusing on improving the lives of his subjects through infrastructure development. His reign saw a notable emphasis on building canals for irrigation, which was crucial for agriculture.

Yamuna Canal: A Key Irrigation Project

Among Firoz Shah Tughlaq's notable contributions to irrigation in the region, including modern-day Haryana, was the construction of the Yamuna Canal. This project aimed to bring the waters of the Yamuna River to arid agricultural lands, thereby increasing crop yields and supporting the population.

• The Yamuna Canal was designed to serve large areas, significantly enhancing the irrigation network.
• This canal system played a vital role in the agricultural prosperity of the territories it supplied.

Evaluating Other Options

Let's consider the other options provided:

• Dam on Ghaggar River: While river systems were vital, the most historically emphasized irrigation contribution of Firoz Shah Tughlaq in Haryana is specifically linked to the Yamuna Canal, not a major dam on the Ghaggar River during his reign.
• Lakes construction in Rohtak: Firoz Shah Tughlaq did undertake various building projects, but the construction of lakes specifically in Rohtak is not highlighted as his primary or most impactful contribution to Haryana's irrigation compared to the extensive canal network.
• Water tax removal: While potentially a beneficial policy for farmers, removing a tax is a fiscal measure and not a direct infrastructural contribution to irrigation systems like building canals. Firoz Shah Tughlaq did impose the 'Haq-i-Sharb' or water tax, so this option contradicts historical records.

Therefore, the construction of the Yamuna Canal stands out as Firoz Shah Tughlaq's most significant and direct contribution to enhancing Haryana's irrigation infrastructure.
