Sasah Volokh has an amusing post at the Volokh Conspiracy. He points out that speakers of English are called Anglophones based on the early settlement of parts of England by the Germanic tribe called Angles. The Angles formed several kingdoms in what is now England, but the Jutes also formed a kingdom, and the Saxons formed kingdoms as well: Essex (East Saxony), Wessex (West Saxony), and Sussex (South Saxony).
When the Danes invaded England, they conquered all the kingdoms except Wessex. Thus, only a Saxon kingdom remained.
Why then, Sasha Volokh asks, aren’t we called–Saxophones?
