Fnd One of the last ruling members of the Carolingian ruling house in the East, Arnulf of Carinthia (Slovene Arnulf Koroški) was illegitimate son of the Bavarian king Carloman and his concubine, Liutswind, of Karantanian origin, born: 850, died: December 8, 899. Upon the death of his uncle, the emperor Charles III the Fat, Arnulf assumed his title of King of the East Franks in 887. Soon after his election for a king the term Karantania became a new European political term.
In Carinthia Carloman had a court in Moosburg (Blatograd), where young Arnulf spent his childhood. From later events it is evident that Karantanians treated him as their own duke.
Arnulf didn't negotiate but he fought. At the decisive Battle of Leuven in 891 he defeated the Normans, who henceforth didn't invade the kingdom anymore.
In 892 Arnulf invaded Great Moravia which lost its independence. In 895 an accord was made between him and the Duke of Bohemia, Borivoj (reigned 870-895) and Bohemia was freed from the danger of Magyar invasion.
Arnulf ruled as Emperor from 896 until his death in 899. He was succeeded as a king of the East Franks by his son, Louis the Child.
After his death his conception of a common Christian Europe remained. This was no more an idiom of a desputy of one mighty emperor as it was in the times of Charlemagne in 8th century, but it was a community of Christian nations.
