Louis de Scarpone, born between 1005 and 1019, died between 1070 and 1073, was the Count of Montbeliard, and Altkirch Ferrette (so that some authors describe as the Earl of Sundgau) and by her marriage to Count Bar and lord of Mousson. He was the son of Richwin, Count of Scarpone and Hildegarde of Eguisheim, sister of Pope Leo IX.
Bar Sophie and her sister Beatrice, daughters of Duke Frederick II of Lorraine were collected in 1033 by Gisèle of Swabia, the wife of the German emperor Conrad II the Salic. The Lorraine was entrusted to the Count de Verdun Gothelon I, but the Emperor wants to strengthen his influence at home face of Verdun who was not slow to show signs of agitation, his niece Sophie married to Louis in 1038. This marriage brought him County Bar and the lordship of Mousson.
A little later, in 1042, the emperor gave the counties of Montbeliard, and Altkirch Ferrette. In 1044, he successfully fought Renaud I, comte de Bourgogne, which had revolted against the emperor.
In 1047, the Duke of Lorraine Godefroy II had revolted and had been defeated. The Lorraine, confiscated, had been given to Adalbert d'Alsace, then Gerard d'Alsace, who died in 1070. Because his wife was the daughter of the first dukes of Lorraine, Louis claimed the Duchy, but the emperor Henry IV cut for Thierry II, the son of Gerard. This was different at the root of the rivalry between the Bar and counts of the dukes of Lorraine, which does rivalry disappear in 1420, with Rene d'Anjou and the union of the two houses.
Louis died shortly thereafter. From his wife Sophie Bar, it was:
* Thierry (1045 † 1105), Count of Montbeliard, Bar and Mousson
* Bruno
* Louis, cited in 1080
* Frederick (1092), Marquis de Suze
* Sophie, married to Folmar, Count of Froburg
* Beatrice († 1092), married to Berthold Duke of Zähringen († 1078), Duke of Carinthia
* Matilda, married Hugues de Dagsburg (1089)
