Can the Hundred Years' War accurately be described as a French civil war?
Short answerYes; rival French-rooted houses were fighting over the right to rule France.
NotesThe Hundred Years' War can be described as a French civil war. At its center was a dispute over who possessed the right to rule France. The English crown's claim grew from Norman and Angevin dynastic roots rather than from a wholly separate national world. Calling the war a civil conflict highlights the competing ruling houses and overlapping identities that a simple England-versus-France label can conceal.
