Thinking with numbers: Quantification and mathematical practices in early 
modern South Asia

Dr. Najaf Haider
Professor of Medieval and Early Modern History
Centre for Historical Studies
Jawaharlal Nehru University, New Delhi


In the late sixteenth century, a series of measures were taken in the Mughal 
Empire (1526-1757 AD) to standardize time, units of weight and measurement and 
currency. The new methods and figures had implications for a large section of 
the society. Transiting to the new system of reckoning was difficult to many 
accustomed with pre-existing traditions. Two major institutions of the Mughal 
Empire, state and market, were directly implicated in the process. The purpose 
of the state was to introduce uniformity in revenue collection and monetization 
while the market preferred diversity. The issue of fixing exchange rates of 
diverse currencies often pitched the state and the money-changers cum bankers 
(sarrafs) against each other and introduced us to the various ways of thinking 
among people about money and value.

Thinking with numbers was evident also in the use statistics and in accountancy 
in written records. Records were kept by government offices, merchants, bankers 
and individual households for planning and reference that nourished learning. 
The professional record keepers equipped themselves with linguistic and 
mathematical skills, the art of notation (raqam), mnemonic devices and the 
ability to translate loosely defined units into precise terms and numbers. In 
the seventeenth century manuals were produced in Persian for the guidance of 
persons seeking to acquire proficiency in accountancy (siyaq), clerical work 
and knowledge of administrative procedures (dasturu’l amal). A work which 
deserves special mention is the Ain-i-Akbari of Abul Fazl, Akbar’s official 
historian. The richness of its statistical material and empirical data on 
agricultural land, revenue rates, state expenditure, cost of minting, exchange 
rates of currencies, and wages and prices is unparalleled. The presentation 
will also look briefly at how modern historians used quantitative and serial 
methods to reconstruct the history of Mughal economy and society.
