Bosonid dynasty

The Bosonids were a dynasty of Franks that have been named in modern times by their descent from Boso the Elder. "Bosonids" produced counts, dukes, bishops during the Carolingian age. Eventually they married into the royal Carolingian family and even produced kings and an emperor of the Frankish Empire.

The first great scion of the dynasty was Boso V, Count of Arles and of other Burgundian counties in the mid-ninth century. Boso rose in favour as a courtier of Charles the Bald. He was even appointed viceroy in Italy in 875. After the death of Charles' son Louis II, Boso refused to recognise both Charles' sons, Carloman and Louis III as kings of France and proclaimed himself King of Provence in 879 at Vienne, with the support of the nobility. Boso strove throughout the rest of his life to maintain his title in the face of the Emperor Charles III. He died in 887 and was succeeded by his son Louis under the regency of his wife Ermengard, a daughter of the Emperor Louis II.

Louis was adopted by Charles III and legitimised in his royal title. With this legal basis, he sought to take the place of his Carolingian relatives on the imperial and Italian thrones in 900. He was crowned in Pavia and then in Rome, but could not actually hold onto power there.
