Mughal Land Revenue System: Zabti, Dahsala & More The Mughal land revenue system reached a well-organised form during the reign of Emperor Akbar, with Raja Todar Mal playing an important role in its development. The system was based on careful measurement of land, classification according to its quality, and collection of revenue largely in cash. The Zabt and Dahsala systems helped make agricultural taxation more systematic, uniform, and easier for the administration to manage.
