the first servant of his people." On the 31st of May 1740 he became king. He maintained all the forms of government established by his father, but ruled in a far more enlightened spirit; he tolerated every form of religious opinion, abolished the use of torture, was most careful to secure an exact and impartial administration of justice, and, while keeping the reins of government strictly in his own hands, allowed every one with a genuine grievance free access to his presence. The Potsdam regiment of giants was disbanded, but the real interests of the army were carefully studied, for Frederick realized that the two pillars of the Prussian state were sound finances and a strong army. On the 20th of October 1740 the emperor Charles VI. died. Frederick at once began to make extensive military preparations, and it was soon clear to all the world that he intended to enter upon some serious enterprise. He had made up his mind to assert the ancient claim of the house of Brandenburg to the three Silesian duchies, which the Austrian rulers of Bohemia had ever denied, but the Hohenzollerns had never abandoned. Projects for the assertion of this claim by force of arms had been formed by more than one of Frederick's predecessors, and the extinction of the male line of the house of Habsburg may well have seemed to him a unique opportunity for realizing an ambition traditional in his family. For this resolution he is often abused still by historians, and at the time he had the approval of hardly any one out of Prussia. He himself, writing of the scheme in his _Memoires_, laid no claim to lofty motives, but candidly confessed that "it was a means of acquiring reputation and of increasing the power of the state." He firmly believed, however, in the lawfulness of his claims; and although his father had recognized the Pragmatic Sanction, whereby the hereditary dominions of Charles VI. were to descend to his daughter, Maria Theresa, Frederick insisted that this sanction could refer only to lands which rightfully belonged to the house of Austria. He could also urge that, as Charles VI. had not fulfilled the engagements by which Frederick William's recognition of the Pragmatic Sanction had been secured, Prussia was freed from her obligation.
