It was probably because of the greatly increased revenue which Akbar obtained by his new method that he found it possible to remit the _jizyeh_ or capitation tax on non-Moslems, and also the tax on pilgrims, which had made the earlier Moslem rule obnoxious to the Hindu population. On the other hand, it may have been not merely religious zeal, but also financial stress caused by the civil wars preceding his accession, by the Rajput revolt, by the long struggle in the Deccan, and by the pious remission of many taxes not authorized by the Sacred Law, including the tax on Hindu temple lands, that influenced Aurangzeb to reimpose the capitation tax, and thus open wide the rifts in his disintegrating empire. In the days of its greatness, the budget of the Mogul Empire, alike in income and expenditure, reached a height which had rarely if ever been attained before. That of the East Roman Empire under the Macedonian dynasty, and of the Saracen Empire in the days of Harun Al-Rashid, may have rivalled it; but it is probable that only the great Western powers, enriched by the industrial revolution in the late nineteenth and early twentieth centuries, have ever reached a financial magnitude beyond that of the empire of Aurangzeb. Humayun divided the responsibilities of government among four ministers, and a fourfold division persisted at least as late as Aurangzeb. By a curious form of logic the classification of duties and the names of the four departments were based, not on convenience, but on relation to the four elements: earth, air, fire, and water. The _Khaki_ department had the care of agriculture, buildings, and domain lands; the _Hawai_, of the wardrobe, the kitchen, the stables, and the like; the _Ateshi_, of the artillery and the making of war material and other things in which fire was employed; and the _Abi_, of the emperor’s drinks, and canals, rivers, and water-works. When Khondamir wrote, about 1534, one man had oversight of all four departments; but the development of a regular supreme official of great power, like the grand vizier of the Ottoman Empire, seems never to have taken place, no doubt because the imperial house did not abandon the tradition of personal government.
