Lothair II
In 858, Count Girart arranged that should Charles of Provence die without heirs, the Kingdom of Provence would revert to Charles' older brother Lothair II who ruled in Lotharingia. When Charles died in 863, his oldest brother Louis II claimed Provence for himself, so the kingdom was divided between the two remaining brothers: Lothair II received the bishoprics of Lyon, Vienne and Grenoble, to be governed by Girart; and Louis II received Arles, Aix-en-provence and Embrun.
