Louis of Montbéliard

Louis of Scarpone (c. 1015–1071/1076) was the son of Count Richwin of Scarpone and Matilda of Eguisheim, sister of Pope Leo IX. In 1038 Emperor Conrad II married him to Sophie of Bar, heiress of the dukes of Upper Lorraine. The marriage brought Louis the county of Bar, and in 1042 the emperor also gave him Montbéliard.

He repulsed Count Renaud I of Burgundy's siege in 1044. After Duke Gerard of Lorraine died in 1070, Louis claimed the duchy through Sophie, but Emperor Henry IV chose Gerard's son Theodoric II. Louis died soon afterwards; his own son Theodoric founded the comital house of Bar.
