Henry the Proud
[3] Henry's father had been promised her marriage and inheritance as reward for his changing to support Lothair in the royal election of 1125 against the Hohenstaufen rival Duke Frederick II of Swabia.[2] In 1136, Henry accompanied his father-in-law to Italy, and taking command of a Bavarian division of the Imperial army marched into the south Italian Kingdom of Sicily up to Bari, devastating the land as he went.Having distinguished himself by his military abilities during this campaign, Henry was appointed as margrave of Tuscany, succeeding Engelbert III of Sponheim, and as Lothair's successor in the Duchy of Saxony.The new king, Conrad III, demanded the Imperial Regalia which Henry had received from Lothair, and the duke in return asked for his investiture with the Saxon duchy.[5] Conrad the Priest probably wrote the Rolandslied, a German version of the Chanson de Roland, while in Henry's service, at the request of Queen Gertrude.
