Ad annum 885. The Northmen entered the territory about Liège, collected all kinds of provisions, and prepared to spend the winter there. But Liutbert, archbishop of Mainz, and count Heimrih, with others, fell upon them suddenly, killed many of them, and drove the others into a small stronghold. They then seized the provisions which the Northmen had collected. The Northmen, after enduring a long siege, during which they suffered from hunger, finally fled from the stronghold by night. 21. Invasion of the Hungarians, _ca._ 950. Thietmar of Merseburg, II, 27; M. G. SS. folio, III, pp. 752 f. Michael, bishop of Regensburg, after governing his diocese well for some years, gathered his troops and joined the other Bavarian nobles in resisting an invasion of the Hungarians. In the battle which followed, our troops were defeated. One of the bishop's ears was cut off, and after receiving many other wounds he was left for dead on the field. One of his personal enemies had fallen at his side, and, by feigning death when the Hungarians searched the battle-field, he escaped with his life. When he saw that he was alone with the bishop whom he hated, he seized a lance and tried to kill him. But the bishop, having recovered consciousness, was able to defend himself, and, after a fierce struggle with his enemy, succeeded in striking him down. After a long and perilous journey the bishop found his way back to Regensburg, greatly to the joy of his flock. All his clergy welcomed him as a bold warrior, his flock honored and cherished him as an excellent pastor, and his wounds and maiming redounded to his honor. 22. Dissolution of the Empire. Regino, M. G. SS. folio, I, pp. 590 ff. The empire divided in 843 was for a brief period reunited under Karl the Fat from 884-887. But the failure of Karl either to enforce his authority in the empire or to protect its boundaries led to his deposition and to the definite division of the empire into small kingdoms under local rulers. Arnulf, an illegitimate son of Karlmann, the brother of Karl the Fat, became king of Germany; in France, as early as 879, Provence or lower Burgundy had elected a local count, Boso, as king; in 888, after the deposition of Karl the Fat, most of the French nobles elected Odo, duke of Francia, who belonged to the family of the counts of Paris, as their king, while upper Burgundy chose its own ruler in count Rudolf, and Aquitaine still held out under its duke for the young Charles the Simple, grandson of Charles the Bald. In Italy Charles the Bald, Ludwig, and Karl the Fat had attempted in vain to assert the authority of the emperor there, and Italy went its own way and became the field of battle between rival claimants for the crown, both of them local Italian nobles. Thus by 888 there were, including Aquitaine, six separate kingdoms, Germany, Italy, France, Aquitaine, Provence, and Burgundy.
