78 THE AGRARIAN SYSTEM OF MOSLEM INDIA trouble Akbar. The ten years which followed Sher Shah’s death were a period of confusion, during which we naturally hear little of the revenue administration. Islam Shah, we are told, replaced Assignments by cash salaries, and abolished all the old regulations regarding them?!; but we find him shortly afterwards offering a choice of Assignments to his brother, and converting cash stipends into Grants of land, so that no permanent change in policy can be in- ferred, and his action was probably intended merely to bring under closer control influential men whom he had reason to distrust. With this exception there is nothing to record, and we may fairly assume that the Revenue Ministry, now known as Diwani, not Diwan, continued, in the absence of orders to the contrary, to carry out Sher Shah’s system in so much of the kingdom as remained intact. In my opinion, it would be a mistake to suppose that conquests of themselves made much difference to this permanent institution. The chief motive of a conqueror, as distinct from a raider, was to secure the revenue of the conquered territory; and, in order to do so, he would have to rely at the outset on the existing machinery for assess- ment and collection. The immediate effect of a conquest would be, on the one hand, to replace some assignees by others, leaving the assignment-system intact; and, on the other hand, to give the Ministry a new master, whose orders would be carried out when they were received. If he gave no new orders, the Ministry would presumably follow the most recent orders, interpreting them in the light of de- partmental tradition, but not making formal changes with- out due authority. A strong King, like Ghiyasuddin Tughlaq in the fourteenth, or Sher Shah in the sixteenth century, might inaugurate his reign by the introduction of new methods: conquerors of a different stamp might be content to accept the methods which they found. Where then there is no record of a change, it is reasonable to assume administrative continuity; but in the period we are now approaching, assumption is unnecessary, for we shall see in the next chapter that Akbar began by adopting Sher Shiah’s methods, and changed them only when they had definitely broken down. 1 Elliot, iv. 470-81. v. 487.
