Arnulf of Carinthia
Carantania retained its internal independence until 818 when the local princes, following the anti-Frankish rebellion of Ljudevit Posavski, were deposed and gradually replaced by a Germanic (primarily Bavarian) ascendancy. Under Emperor Arnulf of Carinthia, Carantania, now ruled by a mixed Bavarian-Slav nobility, briefly emerged as a regional power, but was destroyed by the Hungarian invasions in the late 9th century.
