Reginald I of Bar

Reginald I, called the One-Eyed (c. 1080–1149), ruled as count of Bar from 1105, inheriting Bar and Mousson from his father. In the Investiture Controversy he sided with the pope, and in 1113 Emperor Henry V stormed Bar castle and held him prisoner until he swore homage.

In 1134 he stormed Bouillon, claiming it as an heir of its former lord, but had to return it to the bishop of Liège in 1140. He joined the Second Crusade with his sons and drowned in the Mediterranean on the voyage home, before 10 March 1149.
