CharlemangneHe was the King of the Franks from 768 to 774
date of birth: April 2, 742 ADdate of death: January 28, 814 AD
Charlemange became the king of Franks and the emperor which had helped him become famous. But he also did other things like founded the Holy Roman Empire which also really helped him get more famous.
If Charlemagne never existed the world would have been different because their would have be a different person to be the Kings of Franks and the emperor. Which could have led to a lot of changes throughout history. Also that means there would have been no one to found the Holy Roman Empire.
Charlemagne motivation was because religion
What the world can learn from him is to always be a great leader and help the things you love.
Charlemagnes legacy to me is to always help people when you can.
