- The notion of a king being below an emperor in the feudal order, just as a duke is the rank below a king, is more theoretical than historical. The only kingdom title held within the Holy Roman Empire was the Kingdom of Bohemia, with the Kingdoms of Germany, Italy and Burgundy/Arles being nominal realms. The titles of King of the Germans and King of the Romans were non-landed titles held by the Emperor-elect (sometimes during the lifetime of the previous Emperor, sometimes not), although there were anti-Kings at various points; Arles and Italy were either held directly by the Emperor or not at all. The Austrian and Austro-Hungarian Empires technically contained various Kingdoms (Hungary, Bohemia, Dalmatia, Illyria, Lombardy–Venetia and Galicia and Lodomeria, as well as the Kingdoms of Croatia and Slavonia which were themselves subordinate titles to the Hungarian Kingdom and which were merged as Croatia-Slavonia in 1868), but the Emperor and the King were the same person. The Russian Empire did not include any kingdoms. The short-lived First French Empire (1804–1814/5) did include a number of client kingdoms under Napoleon I, such as the Kingdom of Italy, the Kingdom of Westphalia, the Kingdom of Etruria, the Kingdom of Württemberg, the Kingdom of Bavaria, the Kingdom of Saxony and the Kingdom of Holland. The German Empire (1871-1918) included the Kingdoms of Prussia, Bavaria, Württemberg and Saxony, with the Prussian King also holding the Imperial title.
