294 the Romans agreed. Wazo of Liège, great canonist and stoutest of bishops, had been asked for advice and had urged the restoration of Gregory VI, now an exile in Germany, and, as he held, wrongly deposed. This was one of Wazo's last acts, for on 8 July he died. And the new Pope also died on 9 August 1048. At Ulm in January Henry held a Swabian diet and nominated to the duchy, which had been left vacant for four months, Otto of Schweinfurt, Margrave in the Nordgau, a Babenberg by birth and possibly nephew to Henry's own mother Gisela.

Lorraine remained to be dealt with. In mid-October the two Henries, of France and Germany, met near Metz: France might easily have succoured Godfrey who, spreading "slaughter of men and devastation of fields, the greatest imaginable," had slain his new rival Adalbert. But ecclesiastical matters also pressed; at Christmas the formal embassy from Rome came to speak of the vacant papal throne. They asked for Halinard, Archbishop of Lyons and formerly at Dijon. This prelate, a strict reformer, had refused Lyons in 1041, and asked again to take it later he refused unless he need swear no fealty to Henry. Most German bishops disliked this innovation, but Henry, on the advice of Bruno of Toul, Dietrich of Metz and Wazo of Liège, consented. While archbishop, Halinard had been much in Rome, where he was greatly beloved. But he hesitated long to take new and greater responsibilities, and in the end Bruno of Toul became Pope, and as Leo IX began a new epoch in the Western Church.

To Upper Lorraine Henry had given a new duke, Gerard of Chatenois, who, himself of Lorraine, was brother or uncle of the slain Duke Adalbert and related to Henry and also to the Luxemburgers, while his wife was a Carolingian: he was also founder of a dynasty which ruled Lorraine until 1755. The Bishops of Liège, Utrecht and Metz, together with some lay nobles, had been preparing the way for a larger expedition. In the cold winter of 1048-1049, favoured by the lengthy frost, they defeated and slew Count Dietrich, whose brother Florence followed him in Holland. Then came a greater stroke and in this, too, bishops helped, for Adalbert of Bremen was Henry's right hand. He had already dexterously won over the Billungs; but an even greater triumph was the treaty he had brought about with Svein of Norway and Denmark, who had succeeded Magnus in 1047. Svein was in sympathy with the Empire because of his missionary zeal, and now he brought to its aid his sea-power as his fleet appeared off the Netherland coast. England too, which was friendly since Kunigunda's marriage to Henry and had also seen Flanders under Baldwin become a refuge for its malcontents, kept more distant guard; Edward the Confessor "lay at Sandwich with a multitude of ships until that Caesar had of Baldwin all that he would." Thus Baldwin was unable to "aet-burste on waetere." Another kind of aid was given when Leo IX excommunicated Godfrey and Baldwin at
