Rh Italy he had to face foreign warfare and domestic strife. Polish affairs claimed him first. Boleslav had not sent his promised help to Italy: he had tried to win over Udalrich of Bohemia. Henry tried diplomacy and on its failure set out on a Polish campaign (July 1015). An elaborate plan of an invasion by three armies did not succeed, and Henry himself had a troubled retreat.

During 1016 Henry was busied in Burgundy, and Boleslav was entangled with Russia, where Vladímir the Great was consolidating a principality. In January 1017 Boleslav attempted negotiations, but as he would make no great effort for peace a new expedition was made in August 1017, this time by one strong army and with the hope of Russian help. Sieges and battles did little to decide the issue and Henry again retreated in September 1017. But now Boleslav was inclined for peace, since Russia although it had done but little was a threatening neighbour. The German princes who had suffered heavily were anxious for peace and at Bautzen (30 January 1018) terms were made: a German writer tells us they were the best possible although not seemly; he speaks of no court service or feudal obligations on Boleslav's part. Moreover he kept the marks he had so long desired. Henry had not gained much military glory but he had the peace which was needed. He kept Bohemia as a vassal; he held firmly the German lands west of the Elbe. For the rest of the reign he had peace with Poland.

On the western frontier Burgundy had steadily grown more disordered since 1006. It was the stepping-stone to Italy and Otto the Great had therefore played the part of a protector and feudal superior to the young King Conrad. This connexion had continued and it, as well as disorder, called Henry to Burgundy. The Welf dynasty had lost its former vigour. Conrad "the Pacific" (937-993) was content to appear almost as a vassal of the Emperors. His son, Rodolph III, far from throwing off this yoke became by his weakness more dependent still. Henry for his part had to support Rodolph unless he meant to break with the Saxon tradition of control in Burgundy and to surrender his inherited claim to succession. But in Count Otto—William, ruler of the counties later named Franche-Comté, he found a resolute opponent. It is probable that Otto-William, himself the son of the exiled Lombard King, Adalbert of Ivrea, aimed at the throne, but in any case, like most of the nobles, he feared the accession of a foreign monarch whose first task would be to curb his independence.

By 1016 the ceaseless struggle between Rodolph and his unruly subjects had reached a climax. Rodolph sought for aid from Henry: he came in the early summer to Strasbourg, again acknowledged Henry's right of succession, and promised to do nothing of importance without his advice. Henry acted at once on his newly won right by nominating to a vacant bishopric.

But the proceedings at Strasbourg were met by Otto-William with
