Historians are agreed as to the importance of the fiscal institutions established in Upper India by Sher Shah (1540–1545), but their precise nature is not easy to discover. The difficulty lies mainly in the authorities available. All the published chronicles of the Afghan kingdom derive in effect from the Tārīkh-i Sher Shāhī of Abbās Sarwānī, and the text of this writer has not yet been worked out from the discordant manuscripts which have survived, so that it is not possible to be certain what the chronicler actually wrote in the few and tantalising passages which he devoted to the fiscal system. The only detailed study of the subject which I have seen is contained in Professor Kalikaranjan Qanungo's monograph entitled Sher Shah, which was published in Calcutta in 1921. In what follows I shall have to question some of the Professor's conclusions regarding the fiscal system established by his hero, and it is only fair to begin by saying that my criticisms do not apply to more than a very small proportion of his work. He has not, indeed, faced the problems presented by the text of the Tārīkh, and consequently his study cannot be regarded as definitive, but in the questions of chronology, topography, and psychology which occupy most of his pages he seems to me to have exercised a generally sound judgment along with great industry, and there are not many of his conclusions from which I would dissent.
