Арнульф Каринтийский
In a state of despair, possibly afflicted by severe depression, Louis died at Frankfurt am Main on 20 or 24 September 911, seventeen or eighteen years old. Louis was buried in the monastery of Saint Emmeram in Regensburg, where his father Arnulf of Carinthia lay. His death brought an end to the eastern (German) branch of the Carolingian dynasty.
