Yes. Poitiers is, like most of these battles listed, a big f*ing deal, just not for the reasons usually listed.
I listed Clontarf, which is usually trotted out as a great victory of the Christian Irish over the Pagan Danes driving the "vikings" from Ireland forever. It of course did absolutely no such thing.
It's still really important for a bunch of reasons, such as Brian's inability to form a lasting political legacy for his son and sept, but not because of some "clash of civilizations"
It effected the political career of Charles Martell, which had a few later consequences down the line...
Though now that I think about it, if this was about the rise of Islam, that does seem out of place. Certainly wasn't any more important than say, Kulikovo or any other battle you could pull out of nowhere.
