Jeanne D'Arc has been overused politically.
The real history (without all posterior alterations, political recuperations leading to the rewriting of her story) might be a bit more modest (if there's only a single notable fact remaining).
And yes that was during the "Guerre de Cent Ans" - Hundred Years War (1337 - 1453 but it wasn't a non-stop war, be reassured) - a Civil War in France opposing les Valois (French) and les Plantagenêt (British-backed) but it was essentially during the Revolution and the Prussian Wars that her image was used.
And for your question @sweecee, I think she'll be welcomed with insults and stones :D But even a male prophet would finish the living in the streets, everybody thinking he's a madman.
