William the Conqueror.

Conquered England and defeated the ruler Howard Godwinson during the Battle of Hastings. Harold believed he would lose because at his coronation he saw Haley's comet which everyone though was a demon. The battle lasted 9 hours whereas most of that periods battles only lasted 2 hours which showed both sides had great determination. When William became ruler he was very harsh and gave the best stuff to the french.

Muhammad

Muhammad was orphaned at a very young age. as he grew older he took up meditating on Mount Hira, where the angel Gabriel appeared to him and told him to repeat this verse:

Proclaim! (or read!) in the name of thy Lord and Cherisher, Who created- Created man, out of a (mere) clot of congealed blood: Proclaim! And thy Lord is Most Bountiful,- He Who taught (the use of) the pen,- Taught man that which he knew not

and Muhammad took it upon himself to spread the word of god a lot like Jesus. He became the messenger of Islam and it's Bible was the Qur'an.
