French claimant to the Neapolitan throne. Charles was willing to recognize the Pope as his feudal overlord (a bone of contention with the Hohenstaufens) and was crowned by cardinals in Rome, where Clement IV, permanently established at Viterbo, dared not venture, since the anti-papal Ghibelline party was so firmly in control there. Then, fortified with papal money and supplies, Charles marched into Naples. Having defeated and slain Manfred in the great Battle of Benevento, Charles established himself firmly in the kingdom of Sicily at the conclusive Battle of Tagliacozzo, in which Conradin, the last of the house of Hohenstaufen, was taken prisoner. Clement IV is said to have disapproved of the cruelties committed by his protégé, but the statement by Gregorovius that Clement IV became an accomplice by refusing to intercede for the unfortunate Conradin whom Charles had beheaded in the marketplace of Naples seems contentious. However, Gregorovius may be basing this conclusion on the position of Urban IV's predecessors, Innocent IV and Alexander IV, who were Conradin's official guardians. Acts In 1264, Clement IV renewed the prohibition of the Talmud promulgated by Gregory IX, who had it publicly burnt in France and in Italy. Though Clement did not condemn to death at the stake those who harboured copies of it, and, responding to a denunciation of the Talmud by Pablo Christiani, he ordered that the Jews of Aragon submit their books to Dominican censors for expurgation. In February 1265 Clement summoned Thomas Aquinas to Rome to serve as papal theologian. It was during this period that Aquinas also served as regent master for the Dominicans at Rome. With the arrival of Aquinas the existing studium conventuale at Santa Sabina, which had been founded in 1222, was transformed into the Order's first studium provinciale featuring the study of philosophy (studia philosophiae) as prescribed by Aquinas and others at the chapter of Valenciennes in 1259, an intermediate school between the studium conventuale and the studium generale. This studium was the forerunner of the 16th century College of Saint Thomas at Santa Maria sopra Minerva and the Pontifical University of Saint Thomas Aquinas, Angelicum. In 1266, after the Battle of Benevento, Pope Clement IV conceded for gratitude his coat of arms to the Guelph Party of Florence as official approval to their supremacy and therefore they could take power in many of the other northern Italian cities. In 1267–68 Clement engaged in
