Governors were sent to the towns and cities under its control, and a “captain” was appointed to administer military affairs. High service on the mainland became a prelude to political authority at home. But each city was able to preserve its local privileges, as well as its customary assemblies and magistrates. Only gradually was there a movement towards more professional and bureaucratic structures, with the increasing significance of a small number of aristocratic families. The pattern of Venice was, ineluctably, beginning to repeat itself. The greater bears down upon the lesser. But the dominant city—the
The Venetians also discouraged any enterprise that might challenge the commercial supremacy of their own city, as, for example, the weaving of luxury textiles, so that according to an English observer in the 1760s “every other town in the territory of the Republick appears poor in the comparison of the mother-city.” The innate conservatism of the Venetian state, too, actively discouraged the modernisation of the general economy of the mainland territories. This led directly to Venice’s eventual financial decline. The Italians were not able to compete with the resurgent English and Dutch. The inability or unwillingness to create a state, and a modern state at that, may also have encouraged the fissiparous qualities of the Italian peninsula. In one sense the opportunity for unification and centralisation had been squandered. So Italy remained a prey to foreign powers.
Yet Venice was still secure. It was protected by the lagoon while the plains and hills of northern Italy gave it space against the rival city of Milan; the deep valleys and mountains of the Alpine region afforded it protection against northern rivals. The further the dominion spread, the more jealously it was protected. Issues of self-defence as well as commercial gain were used to justify the absorption of towns and regions. Inaction was no longer possible.
In the first quarter of the fifteenth century, therefore, Venice aligned itself with Florence in order to fight the Visconti family of Milan; this was its first departure from its policy of splendid isolation. There was much opposition to this alliance in Venice itself. Venetian merchants traded very successfully with the Milanese territories and any overreaching by Venice would require the presence of a standing army. Yet the leaders of Venice determined to form an alliance with the free republic of Florence against the tyrants of Milan. The strategy was successful and, with the removal of the Visconti family, Italy reached a state of broad equilibrium amenable to Venetian pressure. There were now no more than five territorial states with their claims and resources finely balanced—Venice, Naples, Florence, Milan and the papal state. Each ruling city and its dependent territories was given the name of
