Describe the work of Todar Mai undertaken for lands and taxes.
Todar Mai carried out a careful survey of crop yields, price and areas cultivated for a 10-years period, 1570-1580. On the basis of this data, tax was fixed on each crop in cash. Each province was divided into revenue circles with its own schedule of revenue rates for individual crops. This revenue system was called ‘zabt’. It was prevalent in those areas where Mughal administrators could survey the land and keep very careful accounts.
