Free ports, political economy, and early globalization: Evidence from 1750s Hamburg

Abstract Recent scholarship locates the origins of modern free trade policies in the early modern free port movement. This historiography has focused on the intellectual and political history of free ports and emphasized the importance of local and regional factors in shaping trade liberalizations in different European countries and colonies. Based on evidence from eighteenth-century Hamburg, this article proposes a different reading: it argues that free trade policies emerged in response to Atlantic trade expansion. The sources suggest that merchants and magistrates were aware of the monumental change which the growth of the Atlantic trade presented and the economic opportunities it provided. The liberalization of individual ports aimed to capture a greater share of that commerce. Free ports therefore constitute an early example of global economic change driving local European policymaking.
