Germany was now about to be aroused from the torpor into which she had been cast by the Thirty Years' War; but her awakening was due, not to the action of the Empire, which was more and more seen to be practically dead, but to the rivalry of two great German states, Austria and Prussia. The latter had long been laying the foundations of her power. Brandenburg, the centre of the Prussian kingdom, was, as we have seen, granted in the 15th century by the emperor Sigismund to Frederick, count of Hohenzollern. In his hands, and in those of his prudent successors, it became one of the most flourishing of the North-German principalities. At the time of the Reformation Albert, a member of a subordinate branch of the house of Hohenzollern, happened to be grand master of the Teutonic Order. He became a Protestant, dissolved the order, and received in fief of the king of Poland the duchy of Prussia. In 1611 this duchy fell by inheritance to the elector of Brandenburg, and by the treaty of Wehlau, in 1657, in the time of Frederick William, the Great Elector, it was declared independent of Poland. By skill, foresight and courage Frederick William managed to add largely to his territories; and in an age of degenerate sovereigns he was looked upon as an almost model ruler. His son, Frederick, aspired to royal dignity, and in 1701, having obtained the emperor's assent, was crowned king of Prussia. The extravagance of Frederick drained the resources of his state, but this was amply atoned for by the rigid economy of Frederick William I., who not only paid off the debts accumulated by his father, but amassed an enormous treasure. He so organized all branches of the public service that they were brought to a point of high efficiency, and his army was one of the largest, best appointed and best trained in Europe (see PRUSSIA: _History_). He died in 1740, and within six months, when Frederick II. was on the Prussian throne, Maria Theresa claimed, in virtue of the pragmatic sanction, the lands and hereditary titles of her father Charles VI.
