Beaujeu gives its name to the famous wine regionBeaujolais and theformer provinceBeaujolais (Biôjolês), of which it is the historical capital. However it was overtaken in the 14th century byVillefranche-sur-Saône, which remains the main commercial centre of the region.
Beaujolais was a semi-autonomous fiefdom of the Lords of Beaujeu. The barony was acquired in the 9th century by Guillaume,Comte du Lyonnais and Count ofForez; on his death, his son Bérard became the first Lord of Beaujeu.
After the death of Edouard II, the barony passed to his uncleLouis II, Duke of Bourbon and was used as a title first by members of the Bourbon family and then by theHouse of Orléans. In 1522,Francis I of France confiscated the title and gave it to his motherLouise of Savoy, but it reverted to the French crown on her death in 1531.
