Roger of Sicily alone had not accepted Innocent; but a foolish attempt to coerce him ended in the defeat and capture of the Pope. In return for the acknowledgment of papal suzerainty, which involved oblivion of the imperial claims, Innocent not only confirmed to Roger and his successors both his conquests in Southern Italy and the royal title, but even, by the grant of the legatine power to the King himself, exempted his kingdom from the visits of papal legates. Roger was supreme in Church and State. A cruel yet vigorous and able ruler, he built up a centralised administrative system from which Henry II of England did not disdain to take lessons. His possession of Sicily carried him to Malta and thence to the north coast of Africa; and before his death in 1154 Tunis was added to his dominions. He was thus one of the greatest among the early Crusaders, and perhaps the most notable ruler of his time. [Sidenote: Conrad III.] Lothair hoped to leave in his son-in-law a successor with irresistible claims. But the very influence to which Lothair owed his own election was now to be cast into the scale against the representative of his family; while the grounds of objection to the succession of Frederick of Hohenstaufen to Henry V now held good against Henry of Bavaria, Saxony, and Tuscany. The Pope and the German nobles were equally afraid of a ruler whose insolent demeanour had already won him the title of "the Proud." They took as their candidate the lately rejected Hohenstaufen Conrad, whose behaviour since his submission had gained him favour in proportion as the conduct of Henry of Bavaria had alienated the other nobles. Conrad was crowned at Aachen by the papal legate, and Henry made his submission. But Conrad, like Lothair, felt himself insecure with so powerful a subject. Accordingly he took away from him the duchy of Saxony, and gave it to the heir of the old dukes in the female line. When Henry refused to accept the decision Conrad put him to the ban of the Empire and deprived him of Bavaria also, which he proceeded to confer upon a relative of his own. But Conrad's obvious attempt to advance his own family offended the nobles, and the death of Henry the Proud in 1139 opened the way for a compromise. Saxony was made over to Henry's youthful son, known in history as Henry the Lion, while Bavaria was to be the wedding portion of Henry the Proud's widow if she married Conrad's relative, who was already Margrave of Austria.
