Gibbon remarks that the oldest royal genealogy of Europe scarcely ascends to the eighth century. The genealogy of the Prussian throne, whether by the zeal of the herald, or the truth of the historian, nearly reaches that cloudy period. Its pedigree is dubiously traced up to the founder of the great Swabian family of Hohenzollern, of whom the first supposed ancestor was a Count Thalasso of Zollern. The family then either fell into obscurity, or rested in contentment with its ancestral possessions, until the thirteenth century, when it started on the national eye as the Burgraves of Nurnberg. But it again slumbered for eight generations, until the difficulties of the Emperor Sigismund drove him to apply to the resources of the family, then probably grown rich, as the chief personages of an opulent German community. The service was repaid by the Viceroyalty of Brandenburg, and the subsequent donation of the actual territory, with the title of Elector, and the office of archchamberlain of the empire. The imperial gratitude probably continued to be reminded of its duties by fresh loans, for the electorate continued to receive frequent additions of territory, until, early in the seventeenth century, the annexation of the duchy of Prussia placed the Elector in an imposing rank among the dependant princes of the Continent. In the middle of this century a man of distinguished ability, fortunately for Prussia, ascended the electoral throne. Germany was then ravaged by the memorable Thirty Years' War. Frederick the Great afterwards expressed the embarrassments of the new reign in a few pithy words, as was his custom: "My great ancestor," said this graphic describer, "was a prince without territory, an elector without power, and an ally without a friend." But talent and time are the true elements of success in every condition of life. By economy the Elector restored his finances; by common sense he reclaimed his half-savage subjects; and by sound policy he continued to augment his dominions, without doing violence to his neighbours. The peace of Westphalia, (1648,) which established the imperial system, gave him the additional importance attached to the possession of the archbishopric of Magdeburg, of Halberstadt, and of the actual sovereignty of ducal Prussia, hitherto held as a Polish fief.
