I think it should be more widely known in the German name, since the Franks were a Germanic tribe.
His empire eventually split up and made both countries, but why did the French name for him take hold throughout the centuries?
I feel like the Germans got a raw deal here, as when I was in school it was taught to me he was French, here I am 20 something years later, and found I was betrayed by the school system again.

Just my history nerd rambling. Don't mind me.
