One of the greatest freedom fighters ever! He saved Western civilization and Christianity from the Muslim hordes.
Bullsh**t! The Byzantine Empire had much more to do with that. Charles Martel won one small battle to keep the muslems from getting to France from Spain. The Byzantine Empire blocked the muslems from entering Europe via Turkey/Greece for over 700 years! This gave Europe time to become powerful enough to repel them on their own.
One of the most overrated Europeans in history, and that's saying something.
