By the treaty of October 1204, the Partition of the Lands of the Roman (Byzantine) Empire, Venice became overnight the inheritor of a maritime empire. At a stroke, the city was changed from a merchant state into a colonial power, whose writ would run from the top of the Adriatic to the Black Sea, across the Aegean and the seas of Crete. In the process its self-descriptions would ascend from the Commune, the shared creation of its domestic lagoon, to the Signoria, the Serenissima, the Dominante—“the Dominant One”—a sovereign state whose power would be felt, in its own proud formulation, “wherever water runs.”
On paper, the Venetians were granted all of western Greece, Corfu, and the Ionian islands, a scattering of bases and islands in the Aegean Sea, critical control of Gallipoli and the Dardanelles, and, most precious of all, three-eighths of Constantinople, including its docks and arsenal, the cornerstone of their mercantile wealth. The Venetians had come to the negotiating table with an unrivaled knowledge of the eastern Mediterranean. They had been trading in the Byzantine Empire for hundreds of years, and they knew exactly what they wanted. While the feudal lords of France and Italy went to construct petty fiefdoms on the poor soil of continental Greece, the Venetians demanded ports, trading stations, and naval bases with strategic control of seaways. None of these were more than a few miles from the sea. Wealth lay not in exploiting an impoverished Greek peasantry, but in the control of sea-lanes along which the merchandise of the East could be channeled into the warehouses of the Grand Canal. Venice came in time to call its overseas empire the Stato da Mar, the “Territory of the Sea.” With two exceptions, it never comprised the occupation of substantial blocks of land—the population of Venice was far too small for that—rather it was a loose network of ports and bases, similar in structure to the way stations of the British Empire. Venice created its own Gibraltars, Maltas, and Adens, and like the British Empire it depended on sea power to hold these possessions together.
This empire was almost an accidental construct. It contained no program for exporting the values of the Republic to benighted peoples; it had little interest in the lives of these unwilling subjects; it certainly did not want them to have the rights of citizens. It was the creation of a city of merchants and its rationale was exclusively commercial. The other beneficiaries of the partition of 1204 concocted scattered kingdoms with outlandish feudal titles—the Latin Empire of Constantinople, the Kingdom of Salonika, the Despotate of Epirus, the Megaskyrate of Athens and Thebes, the Triarchy of Euboea, the Principality of Achaea, the Marquisates of Boudonitza and Salonae—the list was endless. The Venetians styled themselves quite differently. They were proud lords of a Quarter and Half a Quarter of the Empire of Romania. It was a merchant’s precise formulation, coming in total to three-eighths, like a quantity of merchandise weighed in a balance. The Venetians, shrewdly practical and unromantic, thought in fractions: They divided their city into sixths, the capital costs of their ships into twenty-fourths, and their trading ventures into thirds. The places where the flag of Saint Mark was raised and his lion carved on harbor walls and castle gates existed, in the repeated phrase, “for the honor and profit of Venice.” The emphasis was always on the profit.
The Stato da Mar allowed the Venetians to ensure the security of their merchant convoys, and it protected them from the whims of foreign potentates and the jealousy of maritime rivals. Crucially, the treaty afforded full control of trade within the center of the eastern Mediterranean. At a stroke it locked their competitors, the Genoese and the Pisans, out of a whole commercial zone.
Theoretically Byzantium had now been neatly divided into discrete blocks of ownership, but much of this existed only on paper, like the crude maps of Africa carved up by medieval popes. In practice the divisions were far messier. The implosion of the Greek empire shattered the world of the eastern Mediterranean into glittering fragments. It left a power vacuum, the consequences of which no one could foresee—the irony of the Fourth Crusade was that it would advance the spread of Islam, which it had set out to repel. The immediate aftermath was less an orderly distribution than a land grab.
The eastern Mediterranean became a magnet for adventurers and mercenaries, pirates and soldiers of fortune from Burgundy, Lombardy, and the Catalan ports. It was a last Christian frontier for the young and the bold. Tiny principalities sprang up on the islands and plains of Greece, each one guarded by its desolate castle, engaging in miniature wars with its neighbors, feuding and killing. The history of the Latin kingdoms of Greece is a tale of confused bloodshed and medieval war. Few of them lasted long. Dynasties conquered, ruled, and vanished again within a couple of generations, like light rain into the dry Greek earth. They were dogged by continuous, if uncoordinated, Byzantine resistance.
Venice knew better than most that Greece was no El Dorado. True gold was coined in the spice markets of Alexandria, Beirut, Acre, and Constantinople. They impassively watched the feudal knights and mercenary bands hack and hatchet each other and pursued a careful policy of consolidation. They hardly bothered with many of their terrestrial acquisitions. They never claimed western Greece, with the exception of its ports, and unaccountably failed to garrison Gallipoli, the key to the Dardanelles, at all. Adrianople was assigned elsewhere for lack of Venetian interest.
The Venetians’ eyes remained fixed on the sea but they had to fight for their inheritance, continuously dogged by Genoese adventurers and feudal lordlings. This would involve them in half a century of colonial war. Venice was granted the strategic island of Corfu, a crucial link in the chain of islands at the mouth of the Adriatic, but they had to oust a Genoese pirate to secure it and then lost it again five years later. In 1205, they bought Crete from the Crusader lord Boniface of Montferrat for five thousand gold ducats, then spent four years expelling another Genoese privateer, Henry the Fisherman, from the island. They took two strategic ports on the southwest tip of the Peloponnese, Modon and Coron, from pirates, and established a foothold on the long barrier island of Euboea, which the Venetians called Negroponte (the Black Bridge), on the east coast of Greece. And in between they occupied or sublet a string of islands around the south coast of the Peloponnese and across the wide Aegean. It was out of this scattering of ports, forts, and islands that they created their colonial system. Venice, following the Byzantines, referred to this whole geographic area as Romania—the “Kingdom of the Romans,” the word the Byzantines used for it—and divided it up into zones: Lower Romania, which constituted the Peloponnese, Crete, the Aegean islands, and Negroponte; and Upper Romania, the lands and seas beyond, up the Dardanelles to Constantinople itself. Farther still lay the Black Sea, a new zone of potential exploitation.
