On the Political Foundations of the Late Medieval Commercial Revolution: Genoa During the Twelfth and Thirteenth Centuries

Although the late medieval Commercial Revolution is considered to be a watershed in the economic history of Europe, the analysis of the interrelationship between political and economic systems in bringing about this period of economic growth has been neglected. This article conducts such an analysis with respect to the city of Genoa during the twelfth and thirteenth centuries. Viewing political institutions as self-enforcing agreements rather than as exogenous rules, I present and analyze the nature and evolution of Genoa's political systems and the relations between these systems and economic growth.
