The Republic of Venice (; ) was a sovereign state and maritime republic in Northeast Italy, which existed for a millennium between the 8th century and 1797.
It was based in the lagoon communities of the historically prosperous city of Venice, and was a leading European economic and trading power during the Middle Ages and the Renaissance, the most successful of Italy's maritime republics. By the late Middle Ages, it held significant territories in the mainland of northern Italy, known as the Domini di Terraferma, along with most of the Dalmatian coast on the other side of the Adriatic Sea, and Crete and numerous small colonies around the Mediterranean Sea, together known as the Stato da Màr.
A slow political and economic decline had begun by around 1500, and by the 18th century the city of Venice largely depended on the tourist trade, as it still does, and the Stato da Màr was largely lost.
Origins Although no surviving historical records deal directly with the founding of Venice,"Imperciocchè nascendi i principati", begins Apostolo Zeno, Compendio della storia Veneta di Apostolo Zeno continuata fino alla caduta della repubblica 1847:9. the history of the Republic of Venice traditionally begins with the foundation of the city at Noon on Friday, 25 March, AD 421, by authorities from Padua, to establish a trading-post in that region of northern Italy. The founding of the Venetian republic is also said to have been marked at that same event with the founding of the church of St. James. However, the church (believed to be Saint Giacomo di Rialto) dates back no further than the eleventh century, at the earliest, or the mid-twelfth century, at the latest. The 11th century Chronicon Altinate also dates the first settlement in that region, Rivo Alto ("High Shore", later Rialto), to the dedication of that same church (i.e., San Giacometo on the bank of the current Grand Canal).Zeno, Compendio 1847:10.
According to tradition, the original population of the region consisted of refugees—from nearby Roman cities such as Padua, Aquileia, Treviso, Altino, and Concordia (modern Concordia Sagittaria), as well as from the undefended countryside—who were fleeing successive waves of Hun and Germanic invasions from the mid-second to mid-fifth centuries. This is further supported by documentation on the so-called "apostolic families", the twelve founding families of Venice who elected the first doge, who in most cases traced their lineage back to Roman families.
The Quadi and Marcomanni destroyed the main Roman town in the area, Opitergium (modern Oderzo) in AD 166–168. This part of Roman Italy was again overrun in the early 5th century by the Visigoths and by Attila of the Huns who sacked Altinum (a town on the mainland coast of the lagoon of Venice) in 452. The last and most enduring immigration into the north of the Italian peninsula, that of the Lombards in 568, was the most devastating for the north-eastern region, Venetia (modern Veneto and Friuli). It also confined the Italian territories of the Eastern Roman Empire to part of central Italy and the coastal lagoons of Venetia, known as the Exarchate of Ravenna. Around this time, Cassiodorus mentions the incolae lacunae ("lagoon dwellers"), their fishing and their saltworks and how they strengthened the islands with embankments.Cassiodorus, "Variae Epistulae"12.24 The former Opitergium region had finally begun to recover from the various invasions when it was destroyed again, this time for good, by the Lombards led by Grimoald in 667.
As the power of the Byzantine Empire dwindled in northern Italy in the late 7th century, the lagoon communities came together for mutual defence against the Lombards, as the Duchy of Venetia. The Duchy included the patriarchates of Aquileia and Grado, in modern Friuli, by the Lagoon of Grado and Carole, east of that of Venice. Ravenna and the duchy were connected only by sea routes, and with the duchy's isolated position came increasing autonomy. The tribuni maiores formed the earliest central standing governing committee of the islands in the lagoon - traditionally dated to c. 568.
Early in the 8th century, the people of the lagoon elected their first leader Orso Ipato (Ursus), who was confirmed by Byzantium with the titles of hypatus and dux. Historically, Ursus was the first Doge of Venice. Tradition, however, since the early 11th century, dictates that the Venetians first proclaimed one Paolo Lucio Anafesto (Anafestus Paulicius) duke in AD 697, although the tradition dates only from the chronicle of John, deacon of Venice (John the Deacon); nonetheless, the power base of the first doges was in Eraclea.
Initially, the main settlement was elsewhere in the lagoon and not on the islands of the Rialto group which would later be the heart of Venice. One of the few early settlements attested in the Rialto group was the island of Olivolo (now called S. Pietro in Castello), at the western end of the archipelago, closer to the sandbars of the lagoon. Archaeological excavation shows that this island was already inhabited in the 5th century. 6th and 7th century Byzantine imperial seals indicate that, at this time, it was politically important. There was also a castle, perhaps from the 6th century. John the Deacon's early 11th century Chronicon Venetum reports that the diocese of Olivolo was founded in 774-76 by the doge Maurizio Galbaio (764-87), that a bishop Olberio was established in Olivolo by 775 and attributes the foundation of the cathedral of S. Pietro to bishop Orso Partecipazio and its completion to 841. Another attestation of an early settlement in the Rivo Alto group is in what was to become the sestriere (district) of Cannaregio. Whatever early settlements there were in the Rivo Alto group of islands, which was to form the city of Venice, the area did not begin to become properly urbanised until the 9th century.
Rise Orso Ipato's successor, Teodato Ipato, moved his seat from Eraclea to Malamocco (on the Lido) in the 740s. He was the son of Orso and represented the attempt of his father to establish a dynasty. Such attempts were more than commonplace among the doges of the first few centuries of Venetian history, but all were ultimately unsuccessful.
The changing politics of the Frankish Empire began to change the factional division of Venice. One faction was decidedly pro-Byzantine. They desired to remain well-connected to the Empire. Another faction, republican in nature, believed in continuing along a course towards practical independence. The other main faction was pro-Frankish. Supported mostly by clergy (in line with papal sympathies of the time), they looked towards the new Carolingian king of the Franks, Pepin the Short, as the best provider of defence against the Lombards. A minor, pro-Lombard, faction was opposed to close ties with any of these further-off powers and interested in maintaining peace with the neighbouring Lombard kingdom, which surrounded Venice except on the seaward side.
Teodato Ipato was assassinated and his throne usurped, but the usurper, Galla Gaulo, suffered a like fate within a year. During the reign of his successor, Domenico Monegario, Venice changed from a fisherman's town to a port of trade and centre of merchants. Shipbuilding was also greatly advanced and the pathway to Venetian dominance of the Adriatic was laid. Also during Domenico Monegario's tenure, the first dual tribunal was instituted. Each year, two new tribunes were elected to oversee the doge and prevent abuse of power.
In that period because, Venice had established itself a thriving slave trade, buying in Italy, among other places, and selling to the Moors in Northern Africa (Pope Zachary himself reportedly forbade such traffic out of Rome).Duchesne, Louis Marie Olivier.

The pro-Lombard Monegario was succeeded in 764, by a pro-Byzantine Eraclean, Maurizio Galbaio. Galbaio's long reign (764-787) vaulted Venice forward to a place of prominence not just regionally but internationally and saw the most concerted effort yet to establish a dynasty. Maurizio oversaw the expansion of Venetia to the Rialto islands. He was succeeded by his equally long-reigning son, Giovanni. Giovanni clashed with Charlemagne over the slave trade and entered into a conflict with the Venetian church.
Dynastic ambitions were shattered when the pro-Frankish faction was able to seize power under Obelerio degli Antoneri in 804. Obelerio brought Venice into the orbit of the Carolingian Empire. However, by calling in Charlemagne's son Pepin, rex Langobardorum, to his defence, Obelerio raised the ire of the populace against himself and his family and they were forced to flee during Pepin's siege of Venice. The siege proved a costly Carolingian failure. It lasted six months, with Pepin's army ravaged by the diseases of the local swamps and eventually forced to withdraw. A few months later Pepin himself died, apparently as a result of a disease contracted there.
Venice thus achieved lasting independence by repelling the besiegers. This was confirmed in an agreement between Charlemagne and Nicephorus which recognized Venice as Byzantine territory and also recognized the city's trading rights along the Adriatic coast, where Charlemagne previously ordered the Pope to expel the Venetians from the Pentapolis.
Early Middle Ages The successors of Obelerio inherited a united Venice. By the Pax Nicephori (803), the two emperors had recognised Venetian de facto independence, while it remained nominally Byzantine in subservience. During the reigns of Agnello Participazio (–827) and his two sons, Venice grew into its modern form. Around 810, Agnello moved the ducal seat from Malamocco to an island of the Rivo Alto group close to the family's property near the Church of Santi Apostoli, near the eastern bank of the Grand Canal, after Pepin, the Frankish king of Italy, attacked Malamocco but failed to invade the lagoon. This marked the beginning of the urbanisation of the islands of the Rivo Alto group, heart of the modern city of Venice. Agnello's dogeship was marked by the expansion of Venice into the sea through the construction of bridges, canals, bulwarks, fortifications, and stone buildings. The modern Venice, at one with the sea, was being born. Agnello was succeeded by his son Giustiniano, who brought the body of Saint Mark the Evangelist to Venice from Alexandria and made him the patron saint of Venice.
During the reign of the successor of the Participazio, Pietro Tradonico, Venice began to establish its military might which would influence many a later crusade and dominate the Adriatic for centuries, and signed a trade agreement with the Holy Roman Emperor Lothair I, whose privileges were later expanded by Otto I. Tradonico secured the sea by fighting Narentine and Saracen pirates. Tradonico's reign was long and successful (837 – 864), but he was succeeded by the Participazio and it appeared that a dynasty might finally be established.
