Frederick invited his sister to visit him at Reinsberg, to which place either business or pleasure immediately called him. After the lapse of two days, Wilhelmina, with the neglected Queen Elizabeth, repaired to the enchanting chateau, hoping to find, amid its rural scenes, that enjoyment which she never yet had been able to find in the sombre halls of the Berlin palace. Here quite a gay company was assembled. Frederick was very laboriously occupied during the day in affairs of state. But in the evening he appeared in the social circles, attracting the attention of all by his conversational brilliance, and by the apparent heartiness with which he entered into the amusements of the court. He took an active part in some private theatricals, and none were aware of the profound schemes of ambition which, cloaked by this external gayety, were engrossing his thoughts. On the 25th of October a courier arrived, direct from Vienna, with the startling intelligence that the Emperor Charles VI. had died five days before. The king was at the time suffering from a severe attack of chills and fever. There was quite a long deliberation in the court whether it were safe to communicate the agitating intelligence to his majesty while he was so sick. They delayed for an hour, and then cautiously informed the king of the great event. Frederick listened in silence; uttered not a word; made no sign.[36] Subsequent events proved that his soul must have been agitated by the tidings to its profoundest depths. The death of the emperor, at that time, was unexpected. But it is pretty evident that Frederick had, in the sombre recesses of his mind, resolved upon a course of action when the emperor should die which he knew would be fraught with the most momentous results. In fact, this action proved the occasion of wars and woes from which, could the king have foreseen them, he would doubtless have shrunk back appalled. The Emperor Charles VI. left no son. He therefore promulgated a new law of succession in a decree known throughout Europe as the “Pragmatic Sanction.” By the custom of the realm the sceptre could descend only to male heirs. But by this decree the king declared that the crown of the house of Hapsburg should be transmitted to his daughter, Maria Theresa. This law had been ratified by the estates of all the kingdoms and principalities which composed the Austrian monarchy. All the leading powers of Europe--England, France, Spain, _Prussia_, Russia, Poland, Sweden, Denmark, and the Germanic body--had bound themselves by treaty to maintain the “Pragmatic Sanction.” It was a peaceable and wise arrangement, acceptable to the people of Austria and to the dynasties of Europe as a means of averting a war of succession, which might involve all the nations of the Continent in the conflict.
