This book is written by two expert scholars. It tells a fascinating story about a period during the Middle Ages when cultures collided and made war on each other over issues of politics, religion, and wealth (much like the present day). With many views of the famous mosaics in Cefal, Monreale, and Palermo, its 275 color illustrations and four maps provide a beautiful visual complement to an authoritative text.

The Normans originally came to Italy and Sicily in the 11th and 12th centuries looking for adventure or a livelihood, but once there, found opportunity for fame and fortune. The story of the Norman conquest in Italy and Sicily is indeed one of knights and adventurers, great battles and lowly pillage, opportunism and statesmanship, and crusade and coexistence. This rich and often dramatic study focuses on the eight sons of Tancred of Hauteville, especially Robert Guiscard, who has been called "the most dazzling military ruler between Julius Caesar and Napoleon," and his youngest brother Roger, who conquered Sicily. It discusses how they expanded their lands throughout southern Italy, and then took Sicily from its Muslim rulers. The brothers, often in conflict with each other, challenged both the Papacy and the Byzantine Empire, became the main supporters of the reformed Papacy, and founded a rich, sophisticated kingdom that lasted until the nineteenth century.

Histories of medieval Europe have typically ignored southern Italy, looking south only in the Norman period. Yet Southern Italy in the ninth and tenth centuries was a complex and vibrant world that deserves to be better understood. In Before the Normans, Barbara M. Kreutz writes the first modern study in English of the land, political structures, and cultures of southern Italy in the two centuries before the Norman conquests. This was a pan-Meditteranean society, where the Roman past and Lombard-Germanic culture met Byzantine and Islamic civilization, creating a rich and unusual mix.

Preceding and simultaneously with the conquest of England by Duke William, other ambitious and aggressive Norman noblemen (notably the Drengot, De Hauteville and Guiscard families) found it prudent to leave Normandy. At first taking mercenary employment with Lombard rulers then fighting the Byzantine Empire in southern Italy, many of these noblemen achieved great victories, acquired rich lands of their own, and perfected a feudal military system that lasted for 200 years. As news of the rich pickings to be had in the south spread in Normandy, they were joined by many other opportunists – typically, younger sons who could not inherit lands at home. Steadily, these Norman noblemen fought their way to local power, at first in Apulia, then across the Adriatic in Albania, and finally in Muslim Sicily, defeating in the process the armies of Byzantium, the German 'Holy Roman Empire', and Islamic regional rulers. Finally, in 1130, Roger II founded a unified kingdom incorporating southern Italy and Sicily, which lasted until the death of Tancred of Lecce in 1194 – though its legacy long outlasted Norman political rule. This beautifully illustrated title explores not only the Norman armies, but the armies of their opponents, with full-colour plates and expert analysis revealing fascinating details about the fighting men of Normandy, Byzantium, the Arab armies and more.
