Charles of Anjou, after being crowned king of Naples and Sicily by the Pope, and having secured secret advantages by bribery and intrigue, marched against Manfred in 1266. They met at Benevento, where, after a long and bloody battle, Manfred was slain, and the kingdom submitted to the usurper. By the Pope's order, Manfred's body was taken from the chapel where it had been buried, and thrown into a trench: his widow and children were imprisoned for life by Charles of Anjou. [Sidenote: 1268. KONRADIN IN ITALY.] The boy Konradin determined to avenge his uncle's death, and recover his own Italian inheritance. His mother sought to dissuade him from the attempt, but Ludwig of Bavaria offered to support him, and his dearest friend, Frederick of Baden, a youth of nineteen, insisted on sharing his fortunes. Towards the end of 1267, he crossed the Alps and reached Verona with a force of 10,000 men. Here he was obliged to wait three months for further support, and during this time more than two-thirds of his German soldiers returned home. But a reaction against the Guelphs (the Papal party) had set in; several Lombard cities and the Republic of Pisa declared in Konradin's favor, and finally the Romans, at his approach, expelled Pope Urban IV. A revolt against Charles of Anjou broke out in Naples and Sicily, and when Konradin entered Rome, in July, 1268, his success seemed almost assured. After a most enthusiastic reception by the Roman people, he continued his march southward, with a considerable force. On the 22d of August he met Charles of Anjou in battle, and was at first victorious. But his troops, having halted to plunder the enemy's camp, were suddenly attacked, and at last completely routed. Konradin and his friend, Frederick of Baden, fled to Rome, and thence to the little port of Astura, on the coast, in order to embark for Sicily; but here they were arrested by Frangipani, the Governor of the place, who had been specially favored by the Emperor Frederick II., and now sold his grandson to Charles of Anjou for a large sum of money. Konradin having been carried to Naples, a court of distinguished jurists was called, to try him for high treason. With one exception, they pronounced him guiltless of any crime; yet Charles, nevertheless, ordered him to be executed. [Sidenote: 1268.]
