Introduction
This book examines Sicily's place within the religious, diplomatic, military, commercial, and intellectual networks of the Mediterranean world. It traces the history of Sicily, from the sixth-century incorporation of the island into the Byzantine empire, through the period of Muslim rule (827–1061), until the end of Norman rule there in the late twelfth century. In particular, it investigates how Sicily moved from the Latin Christian world into the Greek Christian one, then into the Islamicate civilization, and then back into Latin Christendom. In order to understand Sicily's role(s) within the broader Mediterranean system of the sixth through twelfth centuries, the book explores patterns of travel and communication between Sicily and elsewhere—between Constantinople and Rome, between Byzantium and the Islamic world. Finally, it describes Sicily in the dār al-Islām.
