This fourth collection by David Jacoby focuses on Western economic expansion the Eastern Mediterranean during the 11th-15th centuries. He is concerned to emphasize the interconnections linking the West, Byzantium and the Levant, and to examine normative sources for commercial activity (charters, etc.) against the background of actual practice, such as reflected in notarial documents. The articles deal with the evolution of urban centres, the trade in raw materials, and at the same time questions of technology transfer and the mobility of merchants and craftsmen. Particular attention is given to the silk trade: the author argues that demographic expansion in the Byzantine world, as in the West, stimulated economic growth, and demand for silk led to the emergence of a market-driven industry in Byzantium.

Collected Studies CS1066

The articles in this collection cover the region extending from Italy to the Black Sea and to Egypt, over a period of seven centuries, with an emphasis on the considerable economic and social interaction between the West and the regions of the Eastern Mediterranean. They represent key works in the oeuvre of David Jacoby, the doyen of scholars in the field over many decades.


The customary treatment of Mediterranean trade from the 11th to the mid-15th century emphasizes the predominance of western merchants and the commercial exchange of spices and eastern raw materials for western woollens and other finished products. The studies in this collection, the sixth by David Jacoby to be published in the Variorum series, adopt a different perspective. They underscore the economic vitality of various countries bordering the eastern Mediterranean, their industrial capacity, the importance of exchanges between them, and the important contribution of the merchants based in that region to trans-Mediterranean trade. They also illustrate the role of hitherto neglected commodities, such as timber, iron, silk and cheese, in that trade.

This collection of studies (the eighth by David Jacoby) covers a period witnessing intensive geographic mobility across the Mediterranean, illustrated by a growing number of Westerners engaging in pilgrimage, crusade, trading and shipping, or else driven by sheer curiosity. This movement also generated western settlement in the eastern Mediterranean region. A complex encounter of Westerners with eastern Christians and the Muslim world occurred in crusader Acre, the focus of two papers; a major emporium, it was also the scene of fierce rivalry between the Italian maritime powers. The fall of the crusader states in 1291 put an end to western mobility in the Levant and required a restructuring of trade in the region. The next five studies show how economic incentives promoted western settlement in the Byzantine provinces conquered by western forces during the Fourth Crusade and soon after. Venice fulfilled a major function in Latin Constantinople from 1204 to 1261. The city's progressive economic recovery in that period paved the way for its role as transit station furthering western trade and colonization in the Black Sea region. Venice had also a major impact on demographic and economic developments in Euboea, located along the maritime route connecting Italy to Constantinople. On the other hand, military factors drove an army of western mercenaries to establish in central Greece a Catalan state, which survived from 1311 to the 1380s.
