Silesia was the province which he resolved, in the present helpless situation of the young Queen, to wrest from the house of Austria. He revived some antiquated claims on parts of that duchy. The ancestors of Maria Theresa had not behaved handsomely to the ancestors of Frederick, and the young Queen was now to become a lesson to all princes and states of the real wisdom that always belongs to the honorable and scrupulous performance of all public engagements. Little or nothing, however, can be urged in favor of Frederick. Prescription must be allowed at length to justify possession in cases not very flagrant. The world cannot be perpetually disturbed by the squabbles and collisions of its rulers; and the justice of his cause was, indeed, as is evident from all the circumstances of the case, and his own writings, the last and the least of all the many futile reasons which he alleged for the invasion of the possessions of Maria Theresa, the heiress of the Austrian dominions, young, beautiful, and unoffending, but inexperienced and unprotected. The common robber has sometimes the excuse of want; banditti, in a disorderly country, may pillage, and, when resisted, murder; but the crimes of men, even atrocious as these, are confined at least to a contracted space, and their consequences extend not beyond a limited period. It was not so with Frederick. The outrages of his ambition were to be followed up by an immediate war. He could never suppose that, even if he succeeded in getting possession of Silesia, the house of Austria could ever forget the insult and the injury that had thus been received; he could never suppose, though Maria Theresa might have no protection from his cruelty and injustice, that this illustrious house would never again have the power, in some way or other, to avenge their wrongs. One war, therefore, even if successful, was not to be the only consequence; succeeding wars were to be expected; long and inveterate jealousy and hatred were to follow; and he and his subjects were, for a long succession of years, to be put to the necessity of defending, by unnatural exertions, what had been acquired--if acquired--by his own unprincipled ferocity. Such were the consequences that were fairly to be expected. What, in fact, took place? The seizure of this province of Silesia was first supported by a war, then by a revival of it, then by the dreadful Seven Years' War. Near a million of men perished on the one side and on the other. Every measure and movement of the King's administration flowed as a direct consequence from this original aggression: his military system, the necessity of rendering his kingdom one of the first-rate powers of Europe, and, in short, all the long train of his faults, his tyrannies, and his crimes. We will cast a momentary glance on the opening scenes of this contest between the two houses.
