>iirc king john is considered to be the first plantagenet who was more english than french
Plantagenet was literally a cadet of the house of Anjou.
"more english than french"
He spoke french. If anything the only reason he was "more english" was because he was dumb and lost most of his french lands
>I never mentioned blood (all monarchs had foreign blood), I mentioned language and culture
Exactly my point. You think speaking english made you english, I think the blood was more important.
Of course, being royals none of it mattered.
