(I know, it's other thread abouth Eleanor, but I didn't find any earlier discussion about this possibility).
So, WI instead of two daughters Eleanor of Aquitaine had given birth a son from Louis VII? Let's say her second daughter (Alix) was born a boy. Louis would probably still dislike her, but with a male heir he wouldn't have reasons to annull their marriage. How would it affect the balance of power in France, given that the resources from Eleanor's territories wouldn't go to Henry II and his sons, but to the Capets?
