The present Pantocratorian dynasty is the House of Bourbon-Comnenus-Palaeologus. The family name of the Imperial Family is Capet, like the Kings of France from whom they are descended. Byzantine emperors are traditionally remembered in the style Constantine XI Palaeologus - by this style, the present Emperor's name is Andreus I Capet.
The House of Bourbon-Comnenus-Palaeologus was created by the union between King Louis XVII of France and Empress Theodora II Comnena. The house of the Empress Theodora II was the House of Comnenus-Palaeologus, created by the union between Empress Irene II Palaeologa and Emperor Constantine XIII Comnenus. Empress Irene II was the descendant of the Emperor Demetrius I Palaeologus, who was the illegitimate son of Demetrius Palaeologus, brother of Constantine XI Palaeologus, the last Byzantine Emperor of Constantinople. Emperor Constantine XIII Comnenus was distantly related to the Comnenoi who had ruled Trabzon after the first fall of Constantinople in 1204 to the Fourth Crusade.
The present Imperial Family therefore is descended from the Emperors of the Romans of both Constantinople and Trabzon, and the Kings of France and Navarre. Emperor Andreus I Capet can trace his ancestry back to the successors of Charlemagne, first Emperor of the West, as well as the Emperors of the East.
