It was amidst this state of things that the death of the Emperor Charles VI., on the 20th of October, 1740, occurred, to throw Europe into a new ferment of discord and war. Maria Theresa, the emperor’s eldest daughter, was twenty-three years old, beautiful, virtuous, and of a lofty and resolute character; her rights to the paternal heritage had been guaranteed by all Europe. Europe, however, soon rose, almost in its entirety, to oppose them. The Elector of Bavaria claimed the domains of the house of Austria, by virtue of a will of Ferdinand I., father of Charles V. The King of Poland urged the rights of his wife, daughter of the Emperor Joseph I. Spain put forth her claims to Hungary and Bohemia, appanage of the elder branch of the house of Austria. Sardinia desired her share in Italy. Prussia had a new sovereign, who spoke but little, but was the first to act. Kept for a long while by his father in cruel captivity, always carefully held aloof from affairs, and, to pass the time, obliged to engage in literature and science, Frederick II. had ascended the throne in August, 1740, with the reputation of a mind cultivated, liberal, and accessible to noble ideas. Voltaire, with whom he had become connected, had trumpeted his praises everywhere. The first act of the new king revealed qualities of which Voltaire had no conception. On the 23d of December, after leaving a masked ball, he started post-haste for the frontier of Silesia, where he had collected thirty thousand men. Without preliminary notice, without declaration of war, he at once entered the Austrian territory, which was scantily defended by three thousand men and a few garrisons. Before the end of January, 1741, the Prussians were masters of Silesia. “I am going, I fancy, to play your game,” Frederick had said, as he set off, to the French ambassador: “if the aces come to me we will share.” Meanwhile France, as well as the majority of the other nations, had recognized the young Queen of Hungary. She had been proclaimed at Vienna on the 7th of November, 1740; all her father’s states had sworn alliance and homage to her. She had consented to take to the Hungarians the old oath of King Andreas II., which had been constantly refused by the house of Hapsburg: “If I, or any of my successors, at any time whatsoever, would infringe your privileges, be it permitted you, by virtue of this promise, you and your descendants, to defend yourselves, without being liable to be treated as rebels.”
