 Thanks to the consensual cooperation between the lords and the king, Henry was the first Salian ruler, who had managed to acquire unhindered access to all parts of the empire after a long time and thus able to successfully intervene in political affairs in both the western and eastern imperial estates.Henry visited Saxony several times until 1112, as his relationship with the Saxons was stable during the next years.After the 1106 death of the last member of the Saxon Billung family line Duke Magnus, Henry did not confer the Duchy of Saxony to any of the two sons-in-law, Henry the Black or Otto of Ballenstedt, but to Lothar of Supplinburg, as reward for Lothar's support during the 1104/05 disempowerment of Henry IV.
