Division of Saxony and the other great German duchies.
On returning from his disastrous campaign against the Lombard towns, Frederick Barbarossa found himself at war with the Guelf leader, Henry the Lion (son of Henry the Proud), who had refused to come to the emperor's aid before the battle of Legnano. Henry was banished, and Frederick divided up the Saxon duchy. His policy was to split up the old duchies, for he clearly saw the danger of permitting his vassals to control districts as large as he himself held.
The Hohenstaufens extend their power into southern Italy.
70. Before his departure upon the crusading expedition during which he lost his life, Frederick saw his son, Henry VI, crowned king of Italy. Moreover, in order to extend the power of the Hohenstaufens over southern Italy, he arranged a marriage between the young Henry and Constance, the heiress to the Norman kingdom of Naples and Sicily.[123] Thus the hopeless attempt to keep both Germany and Italy under the same head was continued. It brought about new conflicts with the popes, who were the feudal suzerains of Naples and Sicily, and ended in the ruin of the house of Hohenstaufen.
Henry VI, 1190–1197.
His troubles in Italy and Germany.
Henry VI's short reign was beset with difficulties which he sturdily met and overcame. Henry the Lion, the Guelf leader, having broken the oath he had sworn to Frederick to keep away from Germany, returned and organized a rebellion. So soon as this was quelled and the Guelf party was under control for a time, Henry VI had to hasten south to rescue his Sicilian kingdom. There a certain Norman count, Tancred, was leading a national revolt against the German claimant. The pope, who regarded Sicily as his fief, had freed the emperor's Norman subjects from their oath of fidelity to him. Moreover, Richard the Lion-Hearted of England had landed on his way to the Holy Land and allied himself with Tancred.
Henry VI's expedition to Italy proved a complete disaster. His empress was captured by Tancred's people, his army largely perished by sickness, and Henry the Lion's son, whom he held as a hostage, escaped. To add to his troubles, no sooner had he reached Germany once more than he was confronted by a new and more formidable revolt (1192). Luckily for him, Richard, stealing home through Germany from his crusade, fell into his hands. He held the English king, as an ally of the Guelfs, until he obtained an enormous ransom, which supplied him with the means of fighting his enemies in both Germany and Italy. The death of Tancred enabled him to regain his realms in southern Italy. But he endeavored in vain to induce the German princes to recognize the permanent union of the southern Italian kingdom with Germany, or to make the imperial crown hereditary in his house.
