During the 1920s Belgian historian Henri Pirenne came to an astonishing conclusion: the ancient classical civilization, which Rome had established throughout Europe and the Mediterranean world, was not destroyed by the Barbarians who invaded the western provinces in the fifth century, it was destroyed by the Arabs, whose conquest of the Middle East and North Africa terminated Roman civilization in those regions and cut off Europe from any further trading and cultural contact with the East. According to Pirenne, it was only in the mid-seventh century that the characteristic features of classical life disappeared from Europe, after which time the continent began to develop its own distinctive and somewhat primitive medieval culture.??
Pirennes findings, published posthumously in his Mohammed et Charlemagne (1937), were even then highly controversial, for by the late nineteenth century many historians were moving towards a quite different conclusion: namely that the Arabs were actually a civilizing force who rekindled the light of classical learning in Europe after it had been extinguished by the Goths, Vandals and Huns in the fifth century. And because Pirenne went so diametrically against the grain of this thinking, the reception of his new thesis tended to be hostile. Paper after paper published during the 1940s and 50s strove to refute him. The most definitive rebuttal however appeared in the early 1980s. This was Mohammed, Charlemagne and the Origins of Europe, by English archaeologists Richard Hodges and David Whitehouse. These, in common with Pirennes earlier critics, argued that classical civilization was already dead in Europe by the time of the Arab conquests, and that the Arabs arrived on the scene as civilizers rather than destroyers. Hodges and Whitehouse claimed that the latest findings of archaeology fully supported this view, and their work was highly influential. So influential indeed that over the next three decades Pirenne and his thesisl3½
