Explanation:
The year 622 brought a new challenge to Christianity. Near Mecca, Saudi Arabia, a prophet named Muhammad claimed he received a revelation that became a cornerstone of the Islamic faith. The Koran, which Muhammad wrote in Arabic, identified Jesus Christ not as God but as a prophet. <em><u>Islam</u></em> spread throughout the Middle East and into Europe until 732.Soon thereafter, European Christians began the <em><u>Crusades</u></em>, a campaign of violence against Muslims to dominate the <em><u>Holy Lands</u></em>—an area that extended from modern-day Turkey in the north along the Mediterranean coast to the Sinai Peninsula—under Islamic control, partially in response to sustained Muslim control in Europe. The city of Jerusalem is a holy site for Jews, Christians, and Muslims; evidence exists that the three religions lived there in harmony for centuries. But in 1095, European Christians decided not only to reclaim the holy city from Muslim rulers but also to conquer the entire surrounding area.
The native americans were required to live off of the land and which ever type of geographical region that was, it caused the Natives to adapt.
