When Islam comes to a land, what happens? In this sweeping and thorough historical overview, Emmet Scott answers that question definitively, illuminating the shockingly devastating effects of Islamic encroachment upon Europe during the Middle Ages. This is history with all the timeliness of today's headlines, and an urgent message that our governing authorities ignore at their -- and our -- own risk.

In this excellent follow up to Mohammed and Charlemagne Revisited, Emmet Scott demonstrates that the centuries-long struggle between the Christian world and Islam during the Middle Ages left lasting effects on Christian thought and attitudes. The revival of slavery in the Western world after it was nearly obliterated is quite conclusively shown to be the direct result of prolonged contact with the vast Muslim slave-raiding and trading empire which took millions of slaves from Europe and Africa during the Middle Ages. More controversially, Scott also points to violent antisemitism, iconoclasm, the toleration of torture, extreme religious intolerance and the idea of "holy war" as all having first developed in the Christian world in areas of prolonged contact and war with Islam, most notably in Spain. Scott further demonstrates that while Islam initially conquered the most advanced areas of the world, at a time when Medieval Christendom was a poor backwater, within five centuries the balance of power was completely reversed, with the Islamic world stagnant and deteriorating and the Christian world poised for global domination. This is no accident, but the inevitable result of the opposing world-views created by Islam and Christianity.
Today, the Islamic revival once again threatens Western progress. It is imperative that our leaders become thoroughly acquainted with the history of earlier Islamic advances. The Impact of Islam is a factual, scholarly and unexaggerated look a period of history more relevant today than ever before.
