The Muslim Empire started around the 600's and ended around 1258. The way the Empire spread was out of Mecca, east to India, west across north Africa, and on into Spain. The spread Islam to other people by military conquest, took about 100 years to expand most of their Empire. The Military of Islam were great fighters they believed that if they died in battle that they would go directly to heaven. They treated conquered people fairly, better than previous rulers. The battle of Tours in 732 A. D. was in southern France, The French Christians, under Charles Martel, defeated the Muslims and stopped their advance into Europe. Some contributions to our society from the Muslim Empire are mathematics, astronomy, medicine, Islamic law, architecture, banking, and the main contribute is the preserves of the Greek and Roman culture.
