Duchy of Carniola The Duchy of Carniola (Slovene: "Vojvodina Kranjska" , German: "Herzogtum Krain" ) was a State of the Holy Roman Empire, established under Habsburg rule on the territory of the former East Frankish March of Carniola in 1364. A hereditary land of the Habsburg Monarchy, it became a constituent land of the Austrian Empire in 1804 and part of the Kingdom of Illyria until 1849. A separate crown land from 1849, it was incorporated into the Cisleithanian territories of Austria-Hungary from 1867 until the state's dissolution in 1918. Its capital was Ljubljana.
Kaiserpfalz The term Kaiserpfalz (] , "imperial palace") or Königspfalz (] , "royal palace", from Middle High German "phal[en]ze" to Old High German "phalanza" from Middle Latin "palatia" [plural] to Latin "palatium" "palace") refers to a number of castles and palaces across the Holy Roman Empire that served as temporary, secondary seats of power for the Holy Roman Emperor in the Early and High Middle Ages. The term was also used more rarely for a bishop who, as a territorial lord ("Landesherr"), had to provide the king and his entourage with board and lodging, a duty referred to as "Gastungspflicht".
