Curtin describes how the urge to exchange the goods uniquely available to specific areas has encouraged cultures to meet and exchange ideas as well as goods throughout the centuries. His examples of these exchanges, ranging from Greek city states and West African kingdoms, to Portuguese explorers in the interior of Brazil and Indonesian merchants so accustomed to sailing in search of commerce that they have no home on land, demonstrate the effects on individuals and societies of these meetings, and the accomodations neccesary between merchants to negotiate their differences and get the goods they desire. Along the way we see familiar historical characters in a new light, as with Curtin's discussion of the British trade with Russia and a reexamination of British-Indian trade from the Indian perspective, or his consideration of Spanish competition with the Dutch for South East Asian trade. Players one might not have considered emerge as major powers, as with Armenian trade, from their participation in the Silk Road between Ancient Rome and China, to their invaluable role as cross cultural ambassadors for most of Eurasia up to the nineteenth century. Curtin closes with a consideration of the birth of the modern global industrial economy.

This is a valuable book for any serious student of history and an interseting read for the lay reader as well.
