アンジュー帝国
The term "Angevin Empire" is a neologism defining the lands of the House of Plantagenet: Henry II and his sons Richard I and John. Another son, Geoffrey, ruled Brittany and established a separate line there. As far as historians know, there was no contemporary term for the region under Angevin control; however, descriptions such as "our kingdom and everything subject to our rule whatever it may be" were used. The term "Angevin Empire" was coined by Kate Norgate in her 1887 publication, "England under the Angevin Kings". In France, the term (French for "Plantagenet area") is sometimes used to describe the fiefdoms the Plantagenets had acquired.
