Chapter 6 offers a quantitative examination of the commercial development of Livorno, showing how it plugged local and regional exchange networks into the currents of global commerce. Livorno was at the epicenter of the reorganization of maritime trade in the Tyrrhenian and throughout the Mediterranean. Despite dense connections between north-central Italy and the free port, however, international commerce did not substantially affect productive relations in the hinterland. North-central Italy remained an autonomous region; rather than a colonial outpost subservient to northern capitalism, Livorno was a large marketplace connecting otherwise distinct economies. The Tuscan city’s success in organizing trade eventually provoked a competitive response by neighboring ports.
