In this book Franco Cardini examines the ideas, prejudices, disinformation and anti-information that have formed and coloured Europe's attitude towards Islam. Encompassing 1500 years of ideological interchange and armed conflict, he retells the mutual histories of East and West and examines how and why misunderstanding has occurred

The author focuses primarily on the Islam of the Mediterranean (Turkey, the Middle East and North Africa) with which Europeans came into contact over a long period, but stresses that Islam should not be treated as homogenous. The book concludes with a consideration of the role of Islam within Europe today, a role that is growing yet remains contested.
