Kingdom of Arles
Charles († 863), the youngest of the three sons, became King of Provence, being granted Provence and the greater part of the former Frankish Kingdom of Burgundy (except for the lands west of the Saône river which had been given to West Francia at Verdun and would later become the French Duchy of Burgundy) - this kingdom would later evolve into the Kingdom of Burgundy (also known as Kingdom of Arles from the 12th century)
