- Conquest of Italy and Sicily
Believe it or not but parts of Italy were under Muslim Control. For example Sicily was under Muslim control for 200 years. Most of Southern Italy was under Muslim control. In Italy there were two dominant languages Arabic and Greek minority. The Greek minority were the most rebellious towards the Muslims. But about one fourth to a half of the population of the Italians had become Muslims.The Muslims of southern Italy had reached to Rome, which was like the Makkah for the Christians. But the Muslims moved back down south, instead of continuing to go up. This had a deep effect on the Christians, during the Crusades the Normandies had sandwiched the Muslims, and forced the Muslims to build a wall around the Vatican, because they were terrified that the Muslims would be able to conquer them again.
