Angevin itself is the demonym for the residents of Anjou and its historic capital, Angers; the Plantagenets were descended from Geoffrey I, Count of Anjou, hence the term. The demonym, according to the Oxford English Dictionary, has been in use since 1511. The use of the term Empire has engendered controversy among some historians over whether the term is accurate for the actual state of affairs at the time. The area was a collection of the lands inherited and acquired by Henry, and so it is unclear whether these dominions shared any common identity and so should be labelled with the term Empire. Some historians argue that the term should be reserved solely for the Holy Roman Empire, the only Western European political structure actually named an empire at that time, although Alfonso VII of León and Castile had taken the title "Emperor of all Spain" in 1135. Other historians argue that Henry II's empire was neither powerful, centralised, nor large enough to be seriously called an empire. Furthermore, the Plantagenets never claimed any sort of imperial title as implied by the term Angevin Empire. However, even if the Plantagenets themselves did not claim an imperial title, some chroniclers, often working for Henry II himself, did use the term empire to describe this assemblage of lands. The highest title was "king of England"; the other titles of dukes and counts of different areas held in France were completely and totally independent from the royal title, and not subject to any English royal law. Because of this, some historians, such as W. L. Warren, prefer the term commonwealth to empire, emphasising that the Angevin Empire was more of an assemblage of seven fully independent, sovereign states loosely bound to each other, only united in the person of the king of England. Geography and administration At its largest extent, the Angevin Empire consisted of the Kingdom of England, the Lordship of Ireland, the duchies of Normandy (which included the Channel Islands), Gascony and Aquitaine, as well as of the counties of Anjou, Poitou, Maine, Touraine, Saintonge, La Marche, Périgord, Limousin, Nantes and Quercy. While the duchies and counties were held with various levels of vassalage to the king of France, the Plantagenets held various levels of control over the Duchies of Brittany and Cornwall, the Welsh princedoms, the county of Toulouse, and the Kingdom of Scotland, although those regions were not formal
