The inevitable process was continued in the next reign. Almost all the military glories of Suleiman—known to contemporary Europe as ‘the Magnificent’ and often held by historians the greatest of Osmanli sultans— made for weakening, not strengthening, the empire. His earliest operations indeed, the captures of Rhodes from the Knights and of Belgrade and Šabac from the Hungarians, expressed a legitimate Byzantine policy; and the siege of Malta, one of his latest ventures, might also be defended as a measure taken in the true interests of Byzantine commerce. But the most brilliant and momentous of his achievements bred evils for which military prestige and the material profits to be gained from the oppression of an irreconcilable population were inadequate compensation. This was the conquest of Hungary. It would result in Buda and its kingdom remaining Ottoman territory for a century and a half, and in the principalities of Wallachia and Moldavia abiding under the Ottoman shadow even longer, and passing for all time out of the central European into the Balkan sphere; but also it would result in the Osmanli power finding itself on a weak frontier face to face at last with a really strong Christian race, the Germanic, before which, since it could not advance, it would have ultimately to withdraw; and in the rousing of Europe to a sense of its common danger from Moslem activity. Suleiman’s failure to take Vienna more than made good the panic which had followed on his victory at Mohacs. It was felt that the Moslem, now that he had failed against the bulwark of central Europe, was to go no farther, and that the hour of revenge was near.
