The Anglosphere is the only thing that keeps the world from descending into barbarism

"England is an older country than France" ? Please explain this claim, because it is not clear to me.

Proto-National identity, the 100 year war made the idea of "the french" as more than just "people who serve under the guy who calls himself king of france" whereas "the english" gained such a distinction a few hundred years earlier with the various pre norman invasions.

The question I have is whether or not this formation of a french national identity came before 1422, because if it didn't I'd argue that Gilrandir is right, the french lords might rebel to resist a king they see as foreign, but once Henry V beat them (which I believe he could) the french pesants would just accept being Henry's subjects.
With thier lords supplication or replacment and a vaguely legal looking endorsment by the previous king, the pesantry would just get on with thier lives as subjects of a new king, with the obvious caveat that they didnt get treated worse than they did before.
