The Venetian governmental structure was a mix of Byzantine and Islamic systems, but the social order was entirely feudal. Church and various private properties were tied to military service, though there was no knight tenure within the city itself. The Cavalieri di San Marco was the only order of chivalry ever instituted in Venice, and no citizen could accept or join a foreign order without the government’s consent. Venice remained a republic throughout its independent period and politics and the military were kept completely separate. War was regarded as a continuation of commerce by other means (hence, the city's early production of large numbers of mercenaries for service elsewhere).
Venice (Italian Venezia), the city of canals, is the capital of the region of Veneto, population 274,000 (2003). The city stretches across numerous small islands in a marshy lagoon along the Adriatic Sea in northeast Italy. The saltwater lagoon stretches along the shoreline between the mouths of the Po (south) and the Piave (north) Rivers. The Venetian Republic was a major sea power and a staging area for the Crusades, as well as a very important center of commerce (especially the spice trade) and art in the Renaissance
The Grand Canal is Venice's largest waterway. It forms one of the major water-traffic corridors in the city.
One of the ceremonial duties of the doge was to celebrate the symbolic marriage of Venice with the sea. This was done by casting a ring from the state barge, the Bucentaur, into the Adriatic. In its earlier form this ceremony was instituted to commemorate the conquest of Dalmatia by Doge Pietro II Orseolo in 1000, and was celebrated on Ascension Day. It took its later and more magnificent form after the visit of pope Alexander II and the Holy Roman Emperor Frederick I to Venice in 1177. On state occasions the Doge was surrounded by an increasing amount of ceremonial, and in international relations he had the status of a sovereign prince.
At the same time, however, the expansion of the Ottoman Turks in the Balkans and the Eastern Mediterranean proved threatening to the Venetians. In 1570, the Turks invaded Cyprus, which was conquered by 1571 despite the victory of the Holy League (including significant Venetian forces) at Lepanto later that year. The Venetians soon after made peace, confirming the loss of Cyprus. In the seventeenth century, Crete too was lost, after a long conflict.
In the early years of the republic, the political system can be classified as an autocracy, with the Doge as the almost absolute ruler. In 1223, the aristocratic families of Rialto drastically diminished the powers of the Doge by the establishment of an advisory body that would later be called the Quarantia and a supreme tribunal which would later be called the Signoria. They also created two bodies called sapientes which later grew into six bodies. The combination of sapientes and certain other groups was called a collegio, a kind of ministry to carry out the functions of government. A senate, called the Consiglio dei Pregadi was organized in 1229 with sixty members elected by the Major Council1. During this period the Doge had little real power left, and actual authority was exercised by the Great Council, an extremely limited parliament-like body in which only members of the great aristocratic families of the republic were allowed to participate. Venice claimed that its government was a 'classical republic' because it was a fusion of the three basic forms present in a mixed government: with the regal power in the Doge, the aristocratic in the senate, and the democratic in the Great Council2.
Though Venice was famous for its navy, its army was equally effective. In the 13th century, most Italian city states already were hiring mercenaries, but Venetian troops were still recruited from the lagoon, plus feudal levies from Dalmatia and Istria. In times of emergency, all males between seventeen and sixty years were registered and their weapons were surveyed, with those called to actually fight being organized into companies of twelve. The register of 1338 estimated that 30,000 Venetian men were capable of bearing arms; many of these were skilled crossbowmen. As in other Italian cities, aristocrats and other wealthy men were cavalrymen while the city's conscripts fought as infantry.
In Venice the office of doge was first instituted about 700, replacing tribunes that had led the cluster of early settlements in the lagoon, according to the chronicler John the Deacon, author of the Chronicon Venetum ("Chronicle of Venice"), written about 1000 CE. Whether or not the first doges were technically local representatives of the Emperor at Constantinople, the doge like the Emperor held office for life and was similarly regarded as the ecclesiastical, the civil and the military leader, in the power structure termed caesaropapism. The doge's prerogatives were not defined with precision, and though the position was entrusted to members of the inner circle of powerful Venetian families, after several doges had associated a son with themselves in the ducal office, this tendency towards a hereditary monarchy was checked by a law which decreed that no doge had the right to associate any member of his family with himself in his office, or to name his successor. After 1172 the election of the doge was finally entrusted to a committee of forty, who were chosen by four men selected from the Great Council, which was itself nominated annually by twelve persons. After a deadlocked tie at the election of 1229, the number of electors was increased from forty to forty-one.
By 1303, crossbow practice had become compulsory in the city, with citizens training in groups. As weapons became more expensive and complex to operate, professional soldiers were assigned to help work merchant sailing ships and as rowers in galleys. The company of "Noble Bowmen" was recruited in the later 14th century from among the younger aristocracy and served aboard both war-galleys and armed merchantmen, with the privilege of sharing the captain's cabin.
After a doge's death, a commission of inquisori passed judgment upon his acts, and his estate was liable to be fined for any discovered malfeasance. The official income of the doge was never large, and from early times holders of the office remained engaged in trading ventures. These ventures kept them in touch with the requirements of the grandi.
During the 20th century, when many artesian wells were sunk into the periphery of the lagoon to draw water for local industry, Venice began to subside. It was realised that extraction of the aquifer was the cause. This sinking process has slowed markedly since artesian wells were banned in the 1960s. However, the city is still threatened by more frequent low-level floods (so-called Acqua alta, "high water") that creep to a height of several centimeters over its quays, regularly following certain tides. In many old houses the ground floor is unoccupied due to the periodic floods, but people continue to live and work in the upper stories.
Some recent studies have suggested that the city is no longer sinking, but this is not yet certain; therefore, a state of alert has not been revoked. In May 2003, Silvio Berlusconi, the Italian Prime Minister, inaugurated the "Moses" project, which will lay a series of 79 inflatable pontoons across the sea bed at the three entrances to the lagoon. When tides are predicted to rise above 110 centimetres, the pontoons will be filled with air and block the incoming water from the Adriatic sea. This challenging engineering work is due to be completed by 2011.
The airport was named after the Venetian traveller Marco Polo, who supposedly re-discovered China for the Europeans
The command structure in the army was different from that in the fleet. By ancient law, no nobleman could command more than twenty-five men (to prevent against sedition by private armies), and while the position of Captain General was introduced in the mid-14th century, he still had to answer to a civilian panel of twenty "wise men". Not only was efficiency not degraded, this policy saved Venice from the military takeovers that other Italian city states so often experienced. A civilian commissioner (not unlike a commissar) accompanied each army to keep an eye on things, especially the mercenaries. The Venetian military tradition also was notably cautious; they were more interested in achieving success with a minimum expense of lives and money than in the pursuit of glory.
