Yet Polish patriotism had been a mighty power in the world; and Napoleon, ever on the watch for the weak places of his foes, saw how effective a lever it might be. This had been his constant practice: he had pitted Italians against Austrians, Copts against Mamelukes, Druses against Turks, Irish against English, South Germans against the Hapsburgs and Hohenzollerns, and for the most part with success. But, except in the case of the Italian people and the South German princes, he rarely, if ever, bestowed boons proportionate to the services rendered. It is very questionable whether he felt more warmly for Irish nationalists than for Copts and Druses.[120] Except in regard to his Italian kindred, none of the nationalist aspirations that were to mould the history of the century touched a responsive chord in his nature. In this, as in other affairs of state, he held "true policy" to be "nothing else than the calculation of combinations and chances." It was in this spirit that he surveyed the Polish Question. Arising out of the partitions of that unhappy land by Russia, Austria, and Prussia, it had distracted the repose of Europe scarcely less than the French Revolution; and now the heir to the Revolution, after hewing his way through the weak monarchies of Central Europe, was about to probe this ulcer of Christendom. As usual, nothing had been done to forestall him. Czartoryski had begged Alexander to declare Russian Poland an autonomous kingdom united with Russia only by the golden link of the crown, but this timely proposal was rejected;[121] and the Czar displayed the weakness of his judgment and the strength of his vanity by plunging into war with Turkey and Persia, at a time when Poland was opening her arms to the victor of a hundred fights. It was, therefore, easy for Napoleon to surround Russia with foes; and, as will shortly appear, he took steps to invigorate even the remote Persian Empire. But, above all, he spurred on the Poles to take up arms. His encouragements were discreetly vague. True, he countenanced Polish proclamations, which spoke grandiloquently of national liberty; but proclamations he ever viewed as the _ballons d'essai_ of politics. He also warned Murat not to promise the Poles too much: "My greatness does not depend on the aid of a few thousand Poles. Let them show a firm resolve to be independent: let them pledge themselves to support the King that will be given to them, and then I will see what is to be done."
