The correct answer to this open question is the following.
I choose to write a note on the Muslim ruler Salahuddin.
Born in 1137, in Tikrit, Iraq, Salahuddin al-Ayyubi was best known as Saladin by his western enemies. He was an important political leader and ruler of the Muslims because he was the one who could capture the city of Jerusalem from the Crusader's army in 1187. The Christian crusaders controlled the sacred city of Jerusalem where the Temple of Solomon was located, and Muslims needed to recapture the important place.
Saladin and King Richard battled each other during the third crusade.
The Crusades marked an important place in the history of Europe and the Middle East. In particular, the third crusade started in 1189 and ended in 1192. The Muslims had captured the Temple of Salomon in Jerusalem, in 1187, under the orders of Muslim Sultan Saladin. So the Christian nations such as France, the Roman Empire, and the Kingdom of England, fight back to recuperate the occupied territory.
