Reginald II of Bar

Reginald II (c. 1122–1170) was count of Bar and lord of Mousson from 1149, succeeding his father Reginald I, with whom he had gone on the Second Crusade in 1147. He resumed Bar's feud with the duke of Lorraine and the bishop of Metz.

In 1152 he attacked the abbey of Saint-Mihiel and was excommunicated, making public amends to be absolved. By his marriage in 1155 to Agnes of Champagne, daughter of Count Theobald of Blois and Champagne, he fathered Henry I and Theobald I, who each in turn ruled Bar. He died on 25 July 1170.
