Even to speak of Dark Age economics must raise the eyebrows of a general reader who is accustomed (not unreasonably) to think that the age is called dark because we hardly know about its politics, let alone its economics. Yet the nature and extent of trade and industry in the early Medieval West has been a lively subject of debate for a century. Central to this debate has been the stubbornly immortal 'Pirenne thesis'. Henri Pirenne, one of the great historians of the 20th century, first formulated his thesis in a German prison-camp during the First World War. Pirenne believed that the ancient world was brought to an end, not by the Germanic invasions of the West in the fifth century, but by the Arab invasions of the Mediterranean in the seventh. A Belgian, whose first major work was a history of his native country, Pirenne saw the maritime commerce of the Mediterranean as the key determinant of ancient civilisation. Because, in his view, it survived the Germanic invasions, the barbarian kings of sixth-century Europe were able to maintain the essential style of Roman life and government. When it collapsed, as a result of the Arab conquest of the sea's eastern, southern and western shores, they could no longer do so. The economy of western Europe was reduced to 'natural' levels, its political and cultural centre of gravity shifted northwards into more emphatically 'barbarian' areas, and the result was the emergence of an unashamedly Germanic Roman Emperor in Charlemagne.
