Upon Louis the Stammerer's death, some Frankish nobles advocated electing Louis III as the sole king, but eventually both brothers were elected kings. They were both crowned in September 879.[2] Some doubts were cast upon the legitimacy of their birth,[3] but these disappeared after their victory over theVikings on November of that year.[4] In March 880, the brothers divided their father's realm atAmiens, Carloman receiving the southern kingdoms ofBurgundy andAquitaine.[3]
Meanwhile, the powerful DukeBoso of Provence had renounced his allegiance to both brothers and had been electedKing of Provence on October 879.[4] In 880, Carloman and Louis III marched against Boso and took the northern parts of his realm, starting a two-year siege inVienne. The city was finally taken byRichard, Duke of Burgundy, in 882.[4]
Carloman II died nearLes Andelys while hunting on December 884. He was accidentally stabbed in the leg by his servant Bertoldus while they were attacked by a wild boar.[5] Carloman survived but died seven days later,[5] on 5–6 December.[6][7] He was only about 18 years old.[5] Some modern sources give his death date as 12 December,[3] but this is not corroborated by contemporary sources. Carloman's land were inherited by his cousin, the emperorCharles the Fat.
