God's War: A New History of the Crusades

Across the western Mediterranean, between 1060 and 1091, the island of Sicily, a former Byzantine territory in Muslim hands since the later ninth century, was conquered by armies commanded by lords of Norman French extraction whose presence in the region exemplified the fluidity of high politics where skill in battle plus a private army could propel ambitious warriors, in western Europe as much as in the Near East, to unpredicted eminence. The collapse of an independent post-Carolingian kingdom of Italy in the tenth century had opened the north of the peninsula to German invasion and the assertion of civic independence by the commercial and manufacturing cities and entrepôts of the Po valley (Milan, Venice), Liguria (Genoa) and Tuscany (Florence, Pisa). In the south, Byzantine rule in Apulia and Calabria rubbed uneasily against squabbling local dynasts in Capua, Salerno and Benevento, providing plenty of opportunities for hired professional fighters. The most militarily and politically successful of these came from Normandy, a duchy in northern France with a surplus of arms-bearers and an insufficiency of land, patronage and preferment. Normans, attracted perhaps by a familiar pilgrimage route but certainly by the prospects of profit and improved status, began making their presence felt in south Italian politics from the 1020s. By 1030, one contingent had acquired a permanent hold on Aversa between Naples and Capua. Within thirty years, Norman warlords dominated the area. After a disastrous attempt by Pope Leo IX to put papal theories of temporal jurisdiction into practice by trying to oust them ended in a crushing papal defeat at Civitate in 1053, the Norman lords acquired titles and respectability as the reforming papacy sought protectors. In 1059 Pope Nicholas II (1059–61) recognized Richard of Aversa as prince of Capua and Robert Guiscard as prospective ruler of Byzantine Calabria and Apulia and Muslim Sicily. To reinforce the honour, when Robert Guiscard’s brother, Roger, began the conquest of Sicily in 1060, the enterprise was awarded a papal banner.

The fortunes of Robert Guiscard’s dynasty presaged those of many later crusaders, the family business of war now accorded religious legitimacy and gaining enormous success. Guiscard had conquered Calabria by 1060 and Apulia in 1071 with the surrender of the last Byzantine garrison in Bari. Despite Guiscard’s failure to carve out a principality for his eldest son Bohemund in the western Balkans in the 1080s, to die in 1085 as ruler of southern Italy and arbiter of the destiny of the Vicar of St Peter was no mean feat for a younger son of a minor Norman aristocrat, Tancred of Hauteville. The conquest of Sicily by Guiscard’s brother Roger (d. 1101) provided a new focus for profit and a centre of Norman-Italian political endeavour. Once finally subdued after a bitter three decades’ fighting, Sicily proved far wealthier than the family’s mainland holdings. Under Roger’s son, Roger II, the two parts of the Hauteville inheritance were brought together to the anxiety of popes and western and eastern emperors. In 1130, in return for support, the anti-pope Anacletus II crowned Roger II king of Sicily, Calabria and Apulia, and acknowledged his overlordship over Capua, Naples and Benevento, titles that Roger retained by forcing the legitimate pope, Innocent II, whom he had just defeated and captured, to recognize them in 1139. The combined lands of the kingdom of Sicily created one of the wealthiest, culturally and politically most dynamic, ambitious and disruptive powers of the twelfth-century Mediterranean. By comparison, the Norman-Italian enclave founded by his cousins Bohemund and Tancred in Antioch in 1098 scarcely matched Roger’s lavish regime, which, at its height, sought to emulate, rival, even usurp Byzantium itself. Such entrepreneurial opportunism supplied one vital context for the early crusades. It may have been no coincidence that Alexius I timed his invitation to the west to send military aid shortly after the end of the Sicilian conquest, when, at least in the mind of the canny Greek emperor, there would be available a rich stock of soldiery, some disappointed perhaps at the Sicilian land settlement and eager for new chances to make their fortunes and save their souls.
