Maritime Venice
Byzantine Venetia, also known as the Byzantine Maritime Venetia, or Maritime Venice, was a territory of the Byzantine Empire, within the Exarchate of Ravenna, that existed from the middle of the 6th century, up to the second half of the 7th century. Its territory was corresponding to the coastal belt of ancient Venetia and Istria, encompassing coastal regions of present-day Veneto, and Friuli-Venezia Giulia, including the Venetian Lagoon. Its territory did not include hinterland of the old Venetian province, which was conquered by the Lombards. Within Byzantine domains in Italy, Maritime Venetia had a peripheral position, characterized by a patchwork of settlements without major urban centers, besides Oderzo, the capital city of the province.
History
During the Gothic War, Byzantine rule was established on the entire territory of the ancient Roman province of Venetia and Istria, with its traditional administrative and ecclesiastical center in Aquileia, but already in 568, Italy was invaded by Lombards, who conquered the entire hinterland, including the capital city of Aquileia, thus reducing Byzantine rule to coastal regions of Venetia and Istria. Administrative center of the remaining parts of the province thus moved to Oderzo, while ecclesiastical center moved to Grado, and the province was consequently placed under the jurisdiction of the newly created Exarchate of Ravenna.By the end of the 6th century and during the first half of the 7th century, the remaining territory of the province was further reduced by constant Lombard pressures, and by the end of the 7th century it was practically reduced to the region of Venetian Lagoon, protected by its specific geographical position, that allowed its inhabitants to organize successful defence, aided by maritime support of the powerful Byzantine fleet.
By that time, towns in the region of Venetian Lagoon developed a specific form of political autonomy. The Dogado, or Duchy of Venice was formally established at this time. This was a semi-autonomous nascent city-state under nominal Byzantine jurisdiction, governed by a duke who was to be elected by his peers from the city's ruling class. Its administrative center was the Rialto. According to tradition, Paolo Lucio Anafesto, first Doge of Venice, founded the Republic of Venice in the year 697.
Territory and settlements
Venetia Maritima emerged as a result of the Lombard occupation of a large part of the current Veneto region and the progressive migration of Roman populations. These Romans came from the fall of Aquileia, leading to new coastal settlements, protected by the lagoons and the imperial fleet. The Romans who migrated from mainland Venetia to build new settlements on the Adriatic islands did not intend to permanently abandon the region, as they imagined returning to the cities they'd been forced to evacuate once it was safe to do so. Similar migrations took place in Istria, in the Veneto hinterland between the rivers Adige and Brenta, and in Dalmatia a few decades later following the invasion of the Avars.John the Deacon, writing shortly after the year 1000, described the islands that comprised the province:
Economy
Having largely escaped the upheavals of the Migration Period the local population readily adopted commerce, enabled by the protection afforded by canals and islands and by tax privileges offered by the Byzantine rulers to their Italian subjects. The precarious geographical conditions in Byzantine Venetia favored new social and economic models, stemming from the traditional Roman lagoon activities such as fishing, glass production, and salt extraction.Data on the economic situation of Venetia Maritima were collected thanks to a series of studies carried out on the archaeological excavations of Torcello in the mid-1950s. From the Roman age to the early Middle Ages the territory of the lagoon was used mainly, if not exclusively, for the production of salt or for other minor activities related to fishing and dredging of the coast. Navigation was already important at the time of the reign of the Gothic Vitiges, whose minister Cassiodorus thus addressed the Venetians:
The Roman economic system held up until the beginning of Byzantine rule, and until then the unity of the province was maintained. At the time of Narsete, the various arts already met in guilds, called scholae, protected by a patron: this included the arts of blacksmiths, centonars, fulli, merchants, shopkeepers, stonemasons, potters, painters, etc.
The forced increase of the population due to the migrations from Veneto led to a radical change in the economic production of the area, which from the periphery became a real market. Since the Lombard invasion, a fairly substantial agricultural production was activated, including export products such as pine nuts, walnuts, hazelnuts, peaches and plums, as well as vines and cucumbers, in a local variety still present in Torcello. The growth of the population then led to a second transformation of the territory which, becoming a city area, saw the demand for artisanal products grow. This caused the development of the ceramic industry and finally the glass art. Torcello was about to become a real commercial center, a «μέγαν ἐμπόριον» already in the time of Costantino Porfirogenito. Only the building technique remained the same as the mainland, both in construction materials and in the most common artisan productions, which also felt the influence of the Lombard models.
