In 1781, when the tomb of Frederick was opened, centuries after his death, the institutions he had advocated were but in process of being adopted in Europe. The body of the great emperor was found within the mausoleum, wrapped in embroidered robes, the feet booted and spurred, the imperial crown on its head, in its hand the ball and sceptre, on its finger a costly emerald. For five centuries and more Frederick had slept in state, awaiting the verdict of time on the ideas in defence of which his life had been passed in battle. The verdict had been given, the ideas had grown into institutions, time had vouchsafed the far-seeing emperor his revenge. _THE FALL OF THE GHIBELLINES._ The death of Frederick II., in 1250, was followed by a series of misfortunes to his descendants, so tragical as to form a story full of pathetic interest. His son Enzio, a man of remarkable beauty and valor, celebrated as a Minnesinger, and of unusual intellectual qualities, had been taken prisoner, as we have already told, by the Bolognese, and condemned by them to perpetual imprisonment, despite the prayers of his father and the rich ransom offered. For twenty-two years he continued a tenant of a dungeon, and in this gloomy scene of death in life survived all the sons and grandsons of his father, every one of whom perished by poison, the sword, or the axe of the executioner. It is this dread story of the fate of the Hohenstauffen imperial house which we have now to tell. No sooner had Frederick expired than the enemies of his house arose on every side. Conrad IV., his eldest son and successor, found Germany so filled with his foes that he was forced to take refuge in Italy, where his half-brother, Manfred, Prince of Taranto, ceded to him the sovereignty of the Italian realm, and lent him his aid to secure it. The royal brothers captured Capua and Naples, where Conrad signalized his success by placing a bridle in the mouth of an antique colossal horse's head, the emblem of the city. This insult made the inhabitants his implacable foes. His success was but temporary. He died suddenly, as also did his younger brother Henry, poisoned by his half-brother Manfred, who succeeded to the kingship of the South. But with the Guelphs in power in Germany, and the pope his bitter foe in Italy, he was utterly unable to establish his claim, and was forced to cede all lower Italy, except Taranto, to the pontiff. But a new and less implacable pope being elected, the fortunes of Manfred suddenly changed, and he was unanimously proclaimed king at Palermo in 1258.
