But when the emperor began to govern his distant provinces by viceroys, he was obliged to confide to them a share of his military establishments, the only public establishments which a conqueror thought it worth while to maintain; and while they moved about in their respective provinces, the imperial camp became fixed.  The great officers of state, enriched by the plunder of conquered provinces, began to spend their wealth in the construction of magnificent works for private pleasure or public convenience.  In time, the viceroys began to govern their provinces by means of deputies, who moved about their respective districts, and enabled their masters, the viceroys of provinces, to convert their camps into cities, which in magnificence often rivalled that of the emperor their master.  The deputies themselves in time found that they could govern their respective districts from a central point; and as their camps became fixed in the chosen spots, towns of considerable magnitude rose, and sometimes rivalled the capitals of the viceroys.  The Muhammadans had always a greater taste for architectural magnificence, as well in their private as in their public edifices, than the Hindoos,[10] who sought the respect and good wishes of mankind through the medium of groves and reservoirs diffused over the country for their benefit.  Whenever a Muhammadan camp was converted into a town or city almost all the means of individuals were spent in the gratification of this taste.  Their wealth in money and movables would be, on their death, at the mercy of their prince—­their offices would be conferred on strangers; tombs and temples, canals, bridges, and caravanserais, gratuitously for the public good, would tend to propitiate the Deity, and conciliate the goodwill of mankind, and might also tend to the advancement of their children in the service of their sovereign.  The towns and cities which rose upon the sites of the standing camps of the governors of provinces and districts in India were many of them as much adorned by private and public edifices as those which rose upon the standing camps of the Muhammadan conquerors of Spain.[11] Standing camps converted into towns and cities, it became in time necessary to fortify with walls against any surprise under any sudden ebullition among the conquered people; and fortifications and strong garrisons often suggested to the bold and ambitions governors of distant provinces attempts to shake off the imperial yoke.[12] That portion of the annual revenue, which had hitherto flowed in copious streams of tribute to the imperial capital, was now arrested, and made to augment the local establishments, adorn the cities, and enrich the towns of the viceroys, now become the sovereigns of independent kingdoms.  The lieutenant-governors of these new sovereigns, possessed of fortified towns, in their turn often shook off the yoke of their masters in the same manner, and became in their turn the independent sovereigns of their respective districts.  The whole resources of the countries subject to their rule being employed to strengthen and improve their condition, they soon became rich and powerful kingdoms, adorned with splendid cities and populous towns, since the public establishments of the sovereigns, among whom all the revenues were expended, spent all they received in the purchase of the produce of the land and labour of the surrounding country, which required no other market.
