In this book, Henri Pirenne, the great Belgian economic historian, traces the character and general movement of the economic and social evolution of Western Europe from the end of the Roman Empire to the middle of the fifteenth century. From the breakup of the economic equilibrium of the ancient world to the revival of commerce, the redevelopment of credit, the trade of commodities, the origins of urban industry, and the rebirth of new forms of protectionism, mercantilism, and capitalism, Pirenne presents as complete a picture of the medieval world as is possible in one volume.
