Over the centuries, the name 'Carinthia' ("Kärnten") gradually replaced former 'Carantania'. The realm of the Carinthian dukes initially comprised a vast territory including the marches of Styria ("marchia Carantana"), Carniola and Istria, they also ruled over the Italian March of Verona in the south. Nevertheless, Henry the Younger was the first and also the last Luitpolding duke; as he chose to join the unsuccessful War of the Three Henries against Emperor Otto II, he lost Carinthia two years later and was succeeded by the Emperor's nephew Otto I, a scion of the Salian dynasty. Though Henry once again managed to regain the ducal title in 985, Carinthia upon his death in 989 fell back to the Imperial Ottonian dynasty in Bavaria. Carinthia however remained a separate entity, and in 1012 Count Adalbero I of Eppenstein, Margrave of Styria since about 1000, was vested with the duchy by the last Ottonian emperor Henry II, while the Istrian march was separated and given to Count Poppo of Weimar. Adalbero was removed from office in 1035 after he had fallen out of favour with the Salian Emperor Conrad II. In 1039 Carinthia was inherited by Emperor Henry III himself, who split off the Carniolan march the following year and granted it to Margrave Poppo of Istria. In 1077, the duchy was given to Luitpold, again a member of the Eppensteiner family, which, however, became extinct with the death of Luitpold's younger brother Henry III of Carinthia in 1122. Upon his death the duchy was further reduced in area: a large part of the Eppenstein lands in what is today Upper Styria passed to Margrave Ottokar II of Styria. The remainder of Carinthia passed from Duke Henry III to his godchild Henry from the House of Sponheim, who ruled as Henry IV, from 1122 to his early death the following year. The most outstanding of the Spanheim dukes was Bernhard, the first Carinthian duke who was actually described and honoured in documents as "prince of the land". The last Spanheim duke was Ulrich III; he signed an inheritance treaty with his brother Archbishop Philip of Salzburg, who however could not prevail against the Bohemian king Ottokar II Přemysl.
