Venice is a coastal city in northeastern Italy and the capital of the region of Veneto, as well as the Metropolitan City of Venice. It is built on a group of 126 islands that are separated by expanses of open water and by canals; portions of the city are linked by 472 bridges.
The islands are in the shallow Venetian Lagoon, an enclosed bay lying between the mouths of the Po and the Piave rivers (more exactly between the Brenta and the Sile). As of 2026, the city proper (municipality of Venice) has a population of 249,385, nearly 50,000 of whom live in the historical island city of Venice (centro storico), while most of the population resides on the mainland (terraferma), and about 25,000 live on other islands in the lagoon (estuario).
Together with the cities of Padua and Treviso, Venice is included in the Padua-Treviso-Venice Metropolitan Area (PATREVE), which is considered a statistical metropolitan area, with a total population of 2.6 million.
The name is derived from the ancient Veneti people who inhabited the region by the 10th century BC. The city was the capital of the Republic of Venice for almost a millennium, from 810 to 1797. It was a major financial and maritime power during the Middle Ages and Renaissance, and a staging area for the Crusades and the Battle of Lepanto, as well as an important centre of commerce—especially silk, grain, and spice, and of art from the 13th century to the end of the 17th century. The then-city-state is considered to have been the first real international financial centre, emerging in the 9th century and reaching its greatest prominence in the 14th century. This made Venice a wealthy city throughout most of its history.
For centuries, Venice possessed numerous territories along the Adriatic Sea and within the Italian peninsula, leaving a significant impact on the architecture and culture that can still be seen today. The Venetian Arsenal is considered by several historians to be the first factory in history and was the base of Venice's naval power. The sovereignty of Venice came to an end in 1797, at the hands of Napoleon. Subsequently, in 1866, the city became part of the Kingdom of Italy.
Venice has been known as "La Dominante" ("The Dominant" or "The Ruler"), "La Serenissima" ("The Most Serene"), "Queen of the Adriatic", "City of Water", "City of Masks", "City of Bridges", "The Floating City", and "City of Canals." The lagoon and the city within the lagoon were inscribed as a UNESCO World Heritage Site in 1987, covering an area of 70,176.4 hectares (173,410 acres). Venice is known for several important artistic movements – especially during the Italian Renaissance – and has played an important role in the history of instrumental and operatic music; it is the birthplace of Baroque music composers Tomaso Albinoni and Antonio Vivaldi.
In the 21st century, Venice remains a very popular tourist destination and a major cultural centre, and has often been ranked one of the most beautiful cities in the world. It has been described by The Times as one of Europe's most romantic cities and by The New York Times as "undoubtedly the most beautiful city built by man". However, the city faces challenges, including overtourism, pollution, tide peaks, and cruise ships sailing too close to buildings. Because Venice and its lagoon are under constant threat, Venice's UNESCO listing has been under constant examination.
History
Origins
Although no surviving historical records deal directly with the founding or building of Venice, tradition and the available evidence have led several historians to agree that the original population of Venice consisted of refugees – from nearby Roman cities such as Patavium (Padua), Aquileia, Tarvisium (Treviso), Altinum, and Concordia (modern Portogruaro), as well as from the undefended countryside – who were fleeing successive waves of Germanic and Hun invasions. This is further supported by the documentation on the so-called "apostolic families", the twelve founding families of Venice who elected the first doge, who in most cases trace their lineage back to Roman families. Some late Roman sources reveal the existence of fishermen, on the islands in the original marshy lagoons, who were referred to as incolae lacunae ("lagoon dwellers"). The traditional founding is identified with the dedication of the first church, that of San Giacomo on the islet of Rialto (Rivoalto, "High Shore")—said to have taken place at the stroke of noon on 25 March 421 (the Feast of the Annunciation).
Beginning as early as AD 166–168, the Quadi and Marcomanni destroyed the main Roman town in the area, present-day Oderzo. This part of Roman Italy was again overrun in the early 5th century by the Visigoths and, some 50 years later, by the Huns led by Attila. The last and most enduring immigration into the north of the Italian peninsula, that of the Lombards in 568, left the Eastern Roman Empire only a small strip of coastline in the current Veneto, including Venice. The Roman/Byzantine territory was organized as the Exarchate of Ravenna, administered from that ancient port and overseen by a viceroy (the Exarch) appointed by the Emperor in Constantinople. Ravenna and Venice were connected by just sea routes, and with the Venetians' isolation came increasing autonomy. New ports were built, including those at Malamocco and Torcello in the Venetian lagoon. The tribuni maiores formed the earliest central standing governing committee of the islands in the lagoon, dating from c. 568.
The traditional first doge of Venice, Paolo Lucio Anafesto (Anafestus Paulicius), was elected in 697, as written in the oldest chronicle by John, deacon of Venice c. 1008. Some modern historians claim Paolo Lucio Anafesto was actually the Exarch Paul, and Paul's successor, Marcello Tegalliano, was Paul's magister militum (or "general"), literally "master of soldiers." In 726 the soldiers and citizens of the exarchate rose in a rebellion over the iconoclastic controversy, at the urging of Pope Gregory II. The exarch, held responsible for the acts of his master, Byzantine Emperor Leo III, was murdered, and many officials were put to flight in the chaos. At about this time, the people of the lagoon elected their own independent leader for the first time, although the relationship of this to the uprisings is not clear. Ursus was the first of 117 "doges" (doge is the Venetian dialectal equivalent of the Latin dux ("leader"); the corresponding word in English is duke, in standard Italian duca (see also "duce".)). Whatever his original views, Ursus supported Emperor Leo III's successful military expedition to recover Ravenna, sending both men and ships. In recognition of this, Venice was "granted numerous privileges and concessions" and Ursus, who had personally taken the field, was confirmed by Leo as dux and given the added title of hypatus (from the Greek for "consul").
In 751, the Lombard King Aistulf conquered most of the Exarchate of Ravenna, leaving Venice a lonely and increasingly autonomous Byzantine outpost. During this period, the seat of the local Byzantine governor (the "duke/dux", later "doge"), was at Malamocco. Settlement on the islands in the lagoon probably increased with the Lombard conquest of other Byzantine territories, as refugees sought asylum in the area. In 775/6, the episcopal seat of Olivolo (San Pietro di Castello) was created. During the reign of duke Agnello Particiaco (811–827) the ducal seat moved from Malamocco to the more protected Rialto, within present-day Venice. The monastery of St Zachary and the first ducal palace and Basilica of St. Mark, as well as a walled defense (civitatis murus) between Olivolo and Rialto, were subsequently built here.
Charlemagne sought to subdue the city to his rule. He ordered the pope to expel the Venetians from the Pentapolis along the Adriatic coast; Charlemagne's own son Pepin of Italy, king of the Lombards, under the authority of his father, embarked upon a siege of Venice itself. This, however, proved a costly failure. The siege lasted six months, with Pepin's army ravaged by the diseases of the local swamps and eventually forced to withdraw in 810. A few months later, Pepin himself died, apparently as a result of a disease contracted there. In the aftermath, an agreement between Charlemagne and the Byzantine Emperor Nicephorus in 814 recognized Venice as Byzantine territory, and granted the city trading rights along the Adriatic coast.
By 828, the new city's prestige had increased with the acquisition of relics claimed to be those of St. Mark the Evangelist from Alexandria; these items were placed in the new basilica. Winged lions – visible throughout Venice – are the emblem of St. Mark. The patriarchal seat was also moved to Rialto. As the community continued to develop, and as Byzantine power waned, its own autonomy grew, leading to eventual independence.
Expansion
From the 9th to the 12th centuries, Venice developed into a powerful maritime empire (an Italian thalassocracy known also as repubblica marinara). In addition to Venice there were seven other maritime republics: the most important ones were Genoa, Pisa, and Amalfi; and the lesser known were Ragusa, Ancona, Gaeta and Noli. Its own strategic position at the head of the Adriatic made Venetian naval and commercial power almost invulnerable. The Republic's embrace of sound monetary policies, especially its reliable gold ducat, underpinned growing confidence in Venetian trade and finance, further strengthening its position in international commerce. With the elimination of pirates along the Dalmatian coast, the city became a flourishing trade centre between Western Europe and the rest of the world, especially with the Byzantine Empire and Asia, where its navy protected sea routes against piracy.
The Republic of Venice seized a number of places on the eastern shores of the Adriatic before 1200, mostly for commercial reasons, because pirates based there were a menace to trade. The doge already possessed the titles of Duke of Dalmatia and Duke of Istria. Later mainland possessions, which extended across Lake Garda as far west as the Adda River, were known as the Terraferma; they were acquired partly as a buffer against belligerent neighbors, partly to guarantee Alpine trade routes, and partly to ensure the supply of mainland wheat (on which the city depended). In building its maritime commercial empire, Venice dominated the trade in salt, acquired control of most of the islands in the Aegean, including Crete, and Cyprus in the Mediterranean, and became a major power-broker in the Near East. By the standards of the time, Venice's stewardship of its mainland territories was relatively enlightened and the citizens of such towns as Bergamo, Brescia, and Verona rallied to the defence of Venetian sovereignty when it was threatened by invaders.
Venice remained closely associated with Constantinople, being twice granted trading privileges in the Eastern Roman Empire, through the so-called golden bulls, or "chrysobulls", in return for aiding the Eastern Empire in resisting Norman and Turkish incursions. In the first chrysobull, Venice acknowledged its homage to the empire, but not in the second, reflecting the decline of Byzantium and the rise of Venice's power.
Venice became an imperial power following the Fourth Crusade, which, having veered off course, culminated in 1204 by the capture and sacking of Constantinople and the establishment of the Latin Empire. As a result of this conquest, considerable Byzantine plunder was brought back to Venice. This plunder included the gilt bronze horses from the Hippodrome of Constantinople, which were originally placed above the entrance to the cathedral of Venice, St. Mark's Basilica (the originals have been replaced with replicas, and are now stored within the basilica.) After the fall of Constantinople, the former Eastern Roman Empire was partitioned among the Latin crusaders and the Venetians. Venice subsequently carved out a sphere of influence in the Mediterranean known as the Duchy of the Archipelago, and captured Crete.
The seizure of Constantinople proved as decisive a factor in ending the Byzantine Empire as the loss of the Anatolianthemes, after Manzikert. Although the Byzantines recovered control of the ravaged city a half-century later, the Byzantine Empire was terminally weakened, and existed only as a ghost of its former self, until Sultan Mehmet The Conqueror took the city in 1453.
Situated on the Adriatic Sea, Venice had always enjoyed a strong trade relationship with the Byzantine Empire and the Middle East. By the late 13th century, Venice was the most prosperous city in all of Europe. At the peak of its power and wealth, it had 36,000 sailors operating 3,300 ships, dominating Mediterranean commerce. Venice's leading families vied with each other to build the grandest palaces and to support the work of the greatest and most talented artists. The city was governed by the Great Council, which was made up of members of the noble families of Venice. The Great Council appointed all public officials, and elected a Senate of 200–300 individuals. Since this group was too large for efficient administration, a Council of Ten (also called the Ducal Council, or the Signoria), controlled much of the city administration. One member of the great council was elected "doge", or duke, to be the chief executive; he would usually hold the title until his death, although several doges were pressured by their oligarchical peers to resign and retire into monastic seclusion, when they were felt to have been discredited by political failure.
The Venetian governmental structure was similar in some ways to the republican system of ancient Rome, with an elected chief executive (the Doge), a senate-like assembly of nobles, and the general citizenry with limited political power who originally had the power to grant or withhold their approval of each newly elected Doge. Church and various private property were tied to military service, although 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 separate, except when on occasion the Doge personally headed the military. War was regarded as a continuation of commerce by other means. This tradition justified the city's early employment of large numbers of mercenaries for service elsewhere, and later its reliance on foreign mercenaries when the ruling class was preoccupied with commerce.
Although the people of Venice generally remained orthodox Roman Catholics, the state of Venice was notable for its freedom from religious fanaticism, and executed nobody for religious heresy during the Counter-Reformation. This apparent lack of zeal contributed to Venice's frequent conflicts with the papacy. In this context, the writings of the Anglican divine William Bedell are particularly illuminating. Venice was threatened with the interdict on a number of occasions and twice suffered its imposition. The second, most noted, occasion was in 1606, by order of Pope Paul V.
