Duke of Bar
In the middle of the 10th century, the territory of Bar (Barrois) became a dependency of the Holy Roman Empire. In the 11th century, its lords were counts by title. They belonged to the house of Mousson (which also possessed the countships of Montbéliard and Ferrette) and usually fought in the French ranks. Their neighbors, the dukes of Lorraine, adhered to the German side.
Theobald I of Bar, was an ally of Philip Augustus. His son Henry II who distinguished himself for the French at the battle of Bouvines in 1214. The counts of Bar occasionally took up arms against France.
In 1301 Henry III was vanquished by Philip the Fair. Henry had made an alliance with Edward I of England, whose daughter he had married. Philip forced Henry to do homage for a part of Barrois, situated west of the Meuse River, which was called Barrois mouvant.
In 1354 Robert of Bar, who had married a French princess, was made Marquis of Pont-à-Mousson by the Emperor Charles IV and took the title of Duke of Bar. Hereafter, the title of "Marquis of Pont-à-Mousson" was used by the Dukes of Bar and their heirs. His successor, Edward III of Bar, was killed at Agincourt in 1415.
In 1419 Louis of Bar, brother of the last-named, gave the duchy to René, Duke of Anjou and king of Naples. The Duke was the grandson of his sister Yolande, and had married Isabella, Duchess of Lorraine. Yolande of Anjou, who in 1444 had married Frederick of Lorraine, count of Vaudémont, thereby became heiress of Nicholas of Anjou, duke of Calabria and of Lorraine, in 1473. She then became heir of René of Anjou, duke of Bar, in 1480. Thus Lorraine, with Barrois added to it, once more returned to the family of its ancient dukes.
United with Lorraine to France in 1634, Barrois remained, except for short intervals, part of the royal domain. It was granted in 1738 to Stanislaus Leszczynski, ex-king of Poland, and on his death in 1766 was once more attached to the crown of France.
