Welf I, Duke of Bavaria

1037 - 1101  (64 years)

• Name	Welf I
  Relationship	with Robert Alan Roy
  Birth	1037  [1]
  General Information	He was the first member of the Welf branch of the House of Este. In the genealogy of the Elder House of Welf he is counted as Welf IV.   [4]
  Land/House	1055 (Age 18)  [4]
  When Welf's maternal uncle, Welf, Duke of Carinthia (also known as Welf III), died childless in 1055, Welf inherited his property.
  Title(s)	1070 (Age 33)  [4]
  He was rewarded for his fidelity by being appointed Duke of Bavaria in Otto's stead. This event took place at Goslar in 1070, when the Duchy of Bavaria submitted quietly to the newly made duke, who was the representative of one of the most ancient families in the province. His repudiation of Ethelinde, which could have been considered an act of injustice, does not seem to have been held against him.
  Military	From 1077 to 1085 (Age 40)  [4]
  During the Investiture Controversy, Welf changed sides turning against the Emperor, supporting Pope Gregory VII as well as lending his support for the election of Rudolf of Rheinfelden in March 1077. Pope and Emperor were superficially reconciled in 1076, but the following year saw them again engaged in active hostilities. Henry, in consequence of these repeated acts of rebellion, declared Welf deposed in his newly acquired duchy. However, supported by his faithful Bavarians and aided by his father in Italy, Welf was able to maintain his place, and openly defy the ban of the Empire in May 1077. Welf joined the discontented princes who supported the standard of Rudolph, at a time when any who refused to follow the pope's direction could expect to be excommunicated by the church—a potent and effective threat in the social and political conditions of the time. However, Gregory died in 1085 and his successors took a less intensive part in the affairs of Germany. Welf, though still adhering to the party of the church, began to relax in his exertions to support Rudolf of Rheinfelden.
  Military	1099 (Age 62)  [1, 4]
  In 1099, Welf joined what would become known as the Crusade of 1101, along with William IX of Aquitaine, Hugh of Vermandois and Ida of Austria. His main success was to prevent a clash between fellow Crusaders, who had been pillaging Byzantine territory on their way to Constantinople and the Byzantine emperor's Pecheneg mercenaries. The Crusade itself, entering Anatolia, ended disastrously; after passing Heraclea in September, Welf's Bavarians—like other crusader contingents—were ambushed and massacred by the Turkish troops of Kilij Arslan I, the Seljuq Sultan of Rûm. Welf escaped.
