Notes
https://en.wikipedia.org/wiki/Theodoric_II,_Duke_of_Lorraine
Theodoric II (died 30 December 1115), called the Valiant, was the duke of Lorraine 
from 1070 to his death.[1] He was the son and successor of Gerhard and Hedwige of 
Namur. He is sometimes numbered Theodoric I if the dukes of the House of Ardennes, 
who ruled in Upper Lorraine from 959 to 1033, are ignored in favour of the dukes of 
Lower Lorraine as predecessors of the later dukes of Lorraine.

In fact, Sophia, the daughter of Duke Frederick II of the House of Ardennes, who had 
inherited the counties of Bar and Montbéliard, had a husband named Louis, who 
contested the succession. In order to receive the support of his brother, Theodoric 
gave his brother the County of Vaudémont and convened an assembly of nobles, who 
elected him duke over Louis. Soon Louis was dead, but his son, Theodoric II of Bar, 
claimed the succession anyway. However, Emperor Henry IV confirmed Theodoric the 
Valiant in the duchy. Probably for this reason, Theodoric remained faithful to the 
emperors throughout his rule. He fought the Saxons while they were at war with the 
Emperor between 1070 and 1078 and he opposed the popes Gregory VII and Urban II 
when they were in conflict with the Emperor.

In 1095, he planned to take up the Cross (i.e., go on Crusade, specifically the First), 
but his ill health provoked him to drop out, nevertheless convincing his barons to go 
east. Thereafter, he took little part in imperial affairs, preferring not to intervene 
between Henry IV and his son Henry, or against Lothair of Supplinburg, duke of 
Saxony.
