 Henry V began to strengthen his ties with Saxony, where the opposition against his father was particularly strong due in part to his absence from the duchy since 1089.In the spring of 1105, Henry V stayed in Saxony for two months and showed his willingness to work with the church on the basis of "Gregorian" ideas by removing the bishops, Friedrich von Halberstadt, Udo von Hildesheim, and Henry von Paderborn, who had been appointed by his father.In Quedlinburg, he entered the town barefoot on Palm Sunday, thus demonstrating his humility ("humilitas"), an elementary Christian virtue of rulers.
