Todar Mal and the Mughal Data Survey
In 1580, Emperor Akbar's grand vizier Raja Todar Mal implemented the
Dahsala system, a revolution in imperial statecraft across

northern India. Rather than levying arbitrary taxes or relying on local feudal estimates, Todar Mal dispatched imperial surveyors armed with standardized measuring rods to record exact land area, soil fertility, and crop yields across ten consecutive harvest seasons. By averaging a decade of agricultural data, the Mughal state created a predictable cash-tax model that eliminated systemic price shocks and funded one of the world's most sophisticated imperial bureaucracies. It proved that state stability relied on empirical measurement rather than ad-hoc extraction.
Why today: Just as Raja Todar Mal's 16th-century Mughal survey established data-driven metrics to stabilize resource allocation, modern governments returning to Washington are struggling to build regulatory frameworks around compute infrastructure and artificial intelligence data centers.
