There were revolts and rebellions, as a result of local grievances and factions, but the island remained in Venetian hands for more than four centuries. It can be concluded, therefore, that the Venetians were effectively the first modern colonial power.
Yet in a world dominated by war and empire, there could be no end to rivalry and struggle. In the letters and chronicles of the late fourteenth century the optimism of the Venetians is in some part replaced by intimations of gloom and melancholy; the world seems more uncertain, and the role of providence ill-defined. The loss of confidence is accompanied by the search for greater security in the world. The acquisition of empire, then, brought its own burdens. In 1364 the native inhabitants of Candia rebelled against their Venetian overseers; several Venetian patricians also joined in the revolt. The insurrection was put down, its leaders executed, but it had been a troubling moment for Venice. Petrarch was in the city when the victorious force returned to the lagoon. “We augured good news,” he wrote, “for the masts were garlanded with flowers, and on the deck were lads, crowned with green wreaths and waving flags over their heads …” Relief, as well as triumph, was the emotion of the day. A high mass was celebrated in the basilica, and a great festival was organised in the square itself. Petrarch was present on this occasion, too, and remarked upon the magnificence of the ceremonies. As the empire of Venice became more assured, so the taste for spectacle and ceremonial grew more intense.
Genoa was not quelled by its expulsion from Constantinople. Its traders were dominant in the Black Sea. It held the pre-eminent position in Syria and Palestine. There was never any chance of an enduring peace. In 1350 a Venetian admiral surprised a fleet of fourteen Genoese vessels at the port of Negroponte, and captured ten of them. The other four were allowed to flee simply because the Venetians were too occupied in plundering the cargo of the others. The Venetians and their Greek allies then confronted the Genoese fleet in the Bosphorus, but the battle proved inconclusive. In 1353 the Venetians defeated the Genoese off Sardinia, but a second Genoese fleet began a journey of destruction through the Adriatic and the Aegean. A year later a Venetian fleet was sabotaged and sunk by the Genoese in the port of Modon; the Venetian commanders and their men were taken into custody. It was a signal victory for the Genoese but, even in defeat, the Venetians proved to be expert negotiators. A truce was agreed by means of which each side promised not to attack the other.
The subsequent peace was not, for Venice, a peace at all. It was obliged to cede Dalmatia to the king of Hungary, because of that sovereign’s superior force of arms; it was impelled to withdraw its merchants from Famagusta in Cyprus when the Genoese took over that town. The Venetian fleet kept the Adriatic as its territory, but it was engaged in constant confrontation with the Genoese in the Black Sea. When Venice seized the vital island of Tenedos, controlling access to that sea, the Genoese once again declared war. The Fourth Genoese War was to prove the most terrible, and the most fatal, of all.
The hostilities began in 1378 when a Venetian admiral, Vettor Pisani, sailed west and won a great victory over the Genoese in Genoa’s own waters. But there were complications closer to home. The king of Hungary invited the Genoese to use the Dalmatian coast, opposite Venice, as their centre of operations. It was an opportunity not to be missed. Pisani was obliged to return to the Adriatic, in order to protect Venetian convoys in a gulf that the Venetians had always claimed as their own. His base was at Pola, in Istria, and at the turn of the year the vessels of the fleet were being fitted up and cleaned for future hostilities. But a battle was forced upon them before they could muster all of their ships. The Venetians first had the advantage, when the Genoese admiral was killed, but a reserve force of Genoese ships came forward unexpectedly and overwhelmed the Venetians. Hundreds were killed or captured.
