The reconciliation with Welf IV meant that the Alpine passes were once more open for Henry IV to return to Germany. The journey took place in the spring of 1097, probably through the Brenner Pass, since the first record of Henry on German soil is in Nuβdorf on the River Inn (15 May). He was attended by Welf IV, who must have accompanied him over the Alps. The emperor celebrated Whitsun (24 May) in Regensburg. He depended as much as ever on the material support of Regensburg (making five visits during the next nine years) and the bishop and citizens remained loyal to him to the end of his reign. His court was attended by princes from southern and northern Germany, including Duke Frederick I of Swabia and four Saxon princes: Cuno of Beichlingen (son of Otto of Northeim), Frederick I of Sommerschenburg, the Saxon count palatine, Count Wiprecht I of Groitzsch and Henry I of Eilenburg, margrave of Meissen and of Lower Lusatia (a notable participant in the pacification of Saxony in 1088–9). From Regensburg the imperial entourage moved north to Nuremberg, where ‘very many of the greater men of the kingdom’ had come, the Merseburg chronicler explained, ‘to be reconciled to the king’. The imperial visit to Nuremberg witnessed the formal submission of a number of former rebels, continuing the process of pacification begun in Verona in 1096.
