Preparing Italy and Germany for his death
In 1055, Henry soon turned south, to Italy again, for
Boniface III of Tuscany, ever an imperial ally, had died and his widow,
Beatrice of Bar had married Godfrey of Lorraine (1054). Firstly, however, he gave his old hostage,
Spitignev, the son of Bretislaus to the Bohemians as duke. Spitignev did homage and Bohemia remained securely, loyally, and happily within the Imperial fold. By Easter, Henry had arrived in
Mantua. He held several courts, one at
Roncaglia, where, a century later (1158),
Frederick Barbarossa held a
far more important diet, sent out his
missi dominici to establish order. Godfrey, ostensibly the reason for the visit, was not well received by the people and returned to Flanders. Henry met the pope at
Florence and arrested Beatrice, for marrying a traitor, and her daughter
Matilda, later to be such an enemy of Henry's son. The young
Frederick of Tuscany, Beatrice' son, refused to come to Florence and died within days. Henry returned via
Zürich and there betrothed his young son to Bertha, daughter of Count
Otto of Savoy.
Henry entered a Germany in turmoil. A staunch ally against Cuno in Bavaria, Gebhard of Regensburg, was implicated in a plot against the king along with Cuno and Welf of Carinthia. Sources diverge here: some claim only that these princes' retainers plotted the king's undoing. Whatever the case, it all came to naught and Cuno died of
plague, Welf soon following him to the grave. Baldwin of Flanders and Godfrey were at it again, besieging Antwerp. They were defeated, again. Henry's reign was clearly changing in character: old foes were dead or dying and old friends as well. Herman of Cologne died. Henry appointed his confessor,
Anno, as Herman's successor. Henry of France, so long eyeing Lorraine greedily, met for a third time with the emperor at Ivois in May 1056. The French king, not renowned for his tactical or strategic prowess, but admirable for his personal valour on the field, had a heated debate with the German king and challenged him to single combat. Henry fled at night from this meeting. Once in Germany again, Godfrey made his final peace and Henry went to the northeast to deal with a Slav uprising after the death of William of Meissen. He fell ill on the way and took to bed. He freed Beatrice and Matilda and had those with him swear allegiance to the young Henry, whom he commended the pope, present. On
5 October, not yet forty, Henry died. His heart went to Goslar, his body to Speyer, to lie next to his father's in the family vault in the
cathedral of Speyer. He had been one of the most powerful of the Holy Roman Emperors: his authority as king in Burgundy, Germany, and Italy only rarely questioned, his power over the church was at the root of what the reformers he sponsored later fought against in his son, and his achievement in binding to the empire her tributaries was clear. Nevertheless, his reign is often pronounced a failure in that he apparently left problems far beyond the capacities of his successors to handle. The Investiture Controversy was largely the result of his church politics, though his popemaking gave the Roman diocese to the reform party. He united all the great duchies save Saxonoy to himself at one point or another, but gave them all away. His most enduring and concrete monument may be the impressive palace (
kaiserpfalz) at Goslar.
