It has been waiting, nevertheless, ever since—waiting for much more than a century; and perhaps the end is not even yet. Why, then, have expectations not only within but without the empire been so greatly at fault? How came Montesquieu, Burke, and other confident prophets since their time to be so signally mistaken? There were several co-operating causes, but one paramount. Constantinople was no longer, as in 1453, a matter of concern only to itself, its immediate neighbours, and certain trading republics of Italy. It had become involved with the commercial interests of a far wider circle, in particular of the great trading peoples of western Europe, the British, the French, and the Dutch, and with the political interests of the Germanic and Russian nations. None of these could be indifferent to a revolution in its fortunes, and least of all to its passing, not to a power out of Asia, but to a rival power among themselves. Europe was already in labour with the doctrine of the Balance of Power. The bantling would not be born at Vienna till early in the century to come: but even before the end of the eighteenth century it could be foreseen that its life would be bound up with the maintenance of Constantinople in independence of any one of the parent powers—that is, with the prolongation of the Osmanli phase of its imperial fortunes. This doctrine, consistently acted upon by Europe, has been the sheet anchor of the Ottoman empire for a century. Even to this day its Moslem dynasty has never been without one powerful Christian champion or another. There were, however, some thirty years still to elapse after Selim’s accession before that doctrine was fully born: and had her hands been free, Russia might well have been in secure possession of the Byzantine throne long before 1815. For, internally, the Osmanli state went from bad to worse. The tumultuous insubordination of the Janissaries became an ever greater scandal. Never in all the long history of their riots was their record for the years 1807-9 equalled or even approached. Never before, also, had the provinces been so utterly out of hand. This was the era of Jezzar the Butcher at Acre, of the rise of Mehemet Ali in Egypt, of Ali Pasha in Epirus, and of Pasvanoghlu at Vidin. When Mahmud II was thrust on to the throne in 1809, he certainly began his reign with no more personal authority and no more imperial prestige or jurisdiction than the last Greek emperor had enjoyed on his accession in 1448.
