    Wealth, power and empire (1200–1400)

    Conquest, empire, naval battles, conspiracies, insurrections. The 1200s and 1300s were interesting times for Venice, which was now richer and more powerful than ever.

    Too successful?

    Venice had been extremely successful, and at the start of the 1200s, it was one of the wealthiest cities in Europe, and an important regional power.

    In particular, Venice had succeeded in dominating trade, both within the Byzantine Empire and with the west, to such an extent that it had caused setbacks in Constantinople.

    Venice was born as a Byzantine duchy — which is why Venice had a doge — but during the 1100s Venice had gone to war against Byzantium twice, in defence of its trade.

    The relationship was changing.

    The Fourth Crusade

    In 1201, a delegation of French knights arrived in Venice. They needed a fleet to carry a large crusader army to the Holy Land, which had returned under the control of Muslims.

    This was to be the Fourth Crusade.

    After some wrangling, a deal was struck and a price agreed. Venice was to build a navy of three hundred and fifty ships, to be equipped, manned and ready the next year.

    The Venetians built a ship a day for a year. It is quite a testament to the technological and organisational skills of the Venetians.

    The crusaders arrived during the next spring, and set up camp on the Lido, awaiting departure. There was a problem, though.

    They were too few.

    A crusade was also an act of penitence, and each crusader had to pay for his own journey. Being too few, they couldn’t foot the bill for the fleet which had been agreed the previous year.

    The doge, Enrico Dandolo, eighty years old and blind, was also very shrewd. Another agreement was made, that the crusaders had to solve some problems for the Venetians along the way, to pay their debts.

    In particular, the city of Zara in Dalmatia had rebelled yet again, so when the fleet with the crusaders lifted anchors, their first destination was Dalmatia.

    Ironically, the first thing the fourth crusade did, was to take and subdue a Christian city.

    When the Pope heard, he excommunicated the entire crusade — a detail the commanders didn’t tell the rank and file, though.

    A change of plans

    Further along the journey, during a stopover in a harbour for provisioning, the leaders of the crusade — which included the blind octogenarian doge of Venice — were contacted by Alexios Angelos, the son of the deposed Byzantine emperor Isaac II.

    He promised them money and soldiers for the continuation of the crusade, if they made a detour to Constantinople to return his father to the imperial throne.

    Most of the crusaders took the offer, and the fleet changed course towards the Bosphorus, where they arrived in the summer of 1203.

    After a month of fighting, where the crusaders made some gains, the emperor fled the city, and the blinded Isaac II was restored to power.

    This was the stated goal of the crusaders, but they were cheated of their reward.

    They demanded that Alexios Angelos be made co-emperor, so he could keep his promises. This happened on August 1st.

    Alexios (now Alexios IV Angelos) had difficulty gathering the money he had promised the crusaders, and took to destroying icons and religious items to extract the gold.

    He succeeded in satisfying nobody.

    The crusaders grew more and more impatient, and the citizens of Constantinople restive, as religious objects were desecrated to reward people they saw as barbarians.

    Isaac II died in January 1204, and in February, the leader of the anti-crusader faction in Constantinople overthrew Alexios IV and became Alexios V.

    The Sack of Constantinople

    When Alexios V refused to honour the promises Alexios IV had made, the crusaders renewed their siege of the city.

    Constantinople was heavily fortified, but on April 12th, the crusaders managed to breach the sea walls, and then opens passages in the triple land walls.

    The crusaders sacked Constantinople for three days, stealing and destroying immense treasures.

    Constantinople had been the Roman capital for nine centuries, and it contained unimaginable wealth, much of which was now lost or scattered.

    The porphyry statues of the Tetrarchs, mounted on a corner between the Doge’s Palace and the Basilica of St Mark in Venice, were part of the loot of 1204.

    Likewise, the four gilded horses adorning the façade of the Basilica, came from the hippodrome — the chariot racing grounds in Constantinople, just under the Imperial Palace.

    The treasury of the Basilica of St Mark contains numerous Byzantine objects looted in Constantinople in 1204.

    Dividing an empire

    The crusaders had already made an agreement on the division of the spoils. Venice got three eights, or a bit more than a third of the entire Eastern Roman Empire.

    The victors didn’t, however, manage to secure all parts of the empire for themselves.

    Three parts of the Roman Empire survived as rump states, in Trabzon on the Black Sea coast of Anatolia, in Nicaea in the north-west of Anatolia, and in Epirus in what is now western Greece and Albania.

    Venice got a third of Constantinople, including the harbour areas, and parts of the coast of the Marmara Sea, which was essential for access to the Black Sea, and several major Greek islands. They later bought more islands from other participants of the crusade.

    Doge Dandolo styled himself “Doge of the Venetians and of the Dalmatians, and ruler of a quarter and a half of the Roman Empire”.

    Enrico Dandolo never came back to Venice. He died in 1205, and was buried in the Hagia Sofia.

    The Sea dominion

    In the decade following the conquest of Constantinople, Venice acquired several major Greek islands.

    Corfu ­— which has a strategic position at the entrance to the Adriatic Sea — was held by Venice in the years 1207–1214, after which they lost it again. It came back to Venice in 1386, and then remained Venetian until 1797.

    The coastal cities of Corone and Methoni, on the southern Peloponnese, became Venetian in 1207.

    Candia — the Venetian name for Crete — came under Venetian control in 1211. The people of Candia clearly didn’t approve, as there were many insurrections and rebellions in the following decades.

    While Negroponte (modern Evia) near Athens, strictly speaking, wasn’t Venetian, the Venetians managed to exert a huge influence over it, until they took it over completely in 1390.

    Together with the territories, which Venice already controlled in the Adriatic Sea, this became the Stato di Mar or the Dominio di Mar.

    Venice had become a small empire, with its own overseas territories.

    Overseas territories, which were perfectly located to support Venetian trade.

    Venice did not, however, have political or administrative structures in the 1200s to manage such distant territories. They were therefore often simply handed over to members of the Venetian elite, who then ran them as semi-autonomous, but Venetian aligned, mini states. Some, like the Duchy of Naxos, lasted for centuries.

    Trade competitors

    Before the Latin conquest of Constantinople, the Byzantine emperors had tried to curb the influence of the Venetian merchants on the economy of the city.

    After the conquest, Venice governed a third of the city, and could do whatever it wanted.

    The main competitors of Venice, in particular Pisa and Genoa, were favoured by the Byzantine rump states of Nicaea, Trabzon and Epirus, but Venetian dominance in the Eastern Mediterranean was as firm as ever.

    Genoa was the most important of the competitors to Venice, and there would be many wars between the two in the 1200s and 1300s. Many of these fights would take place in the Eastern Mediterranean, but they also fought much closer to home, as we shall see later.

    The loss of Constantinople

    Acre in the Kingdom of Jerusalem was the main harbour city of the kingdom, and had both Venetian and Genovese merchants resident. In 1255, the enmity between the two groups flared up, and the Genovese raided the Venetian quarters.

    The ensuing War of Saint Sabas lasted until 1270. The Venetians sent a fleet, which entered Acre, destroyed the Genovese quarters, and expelled the survivors.

    Around Constantinople, the Latin Empire of the East was much weakened, as the Byzantine rump states of Nicaea and Epirus slowly took back territory.

    Genoa approached Michael VIII Palaiologos of Nicaea, and made an alliance for the reconquest of Constantinople. Genoa would help Nicaea take back the city, and in return, they would get all the territories and privileges the Venetians had.

    In 1261, Nicaea retook Constantinople, but before the Genovese arrived to help.

    Trade to and from Constantinople and access to the Black Sea was now in the hands of Genoa, which thereby dealt a major blow to Venice.

    The Venetians weren’t, however, completely expelled from the city. A few years later, as the relationship between the Byzantines and the Genovese soured, new treaties between Constantinople and Venice were negotiated.

    Venice also tried to create a Latin alliance to make a repeat of the Fourth Crusade, but those attempts failed, partly because of an anti-French rebellion in Sicily in 1282 — the Sicilian Vespers.

    The Byzantine Empire had been restored, but much weaker, and just as dependent on western merchants — predominantly Venetian and Genovese — as it had been before the Fourth Crusade.

    Locking the council

    The Greater Council, which was established after the crisis of 1172, had taken over the creation of doges and of most other magistrates of the republic. It had, de facto, become the constitutional backbone of the republic — the highest authority of the state.

    The Venetian Republic didn’t have any formal constitution, and the creation of “constitutional bodies” happened as need arose. Venetian statehood wasn’t planned — it just happened — and there was no design, and no real constitution. The Venetian elite simply made up the rules as it went.

    The concentration of power in the Greater Council, and the lack of formal rules, led to a conflict within the Venetian elite about who should be part of the council.

    In practice, two dozen or so of the oldest and riches families in the city had dominated the council for the first century.

    In the 1260s, of 430 members of the Greater Council, over half came from just twenty-seven families. Their names and coat of arms are still visible all over the city. They were, among others, the Contarini, Querini, Dandolo, Morosini, Michiel, Falier, Zorzi, Tiepolo, Gradenigo, Badoer, Zen, Dolfin, and Corner.

    Two loose factions formed within the elite. One side wanted the membership to be more restricted and centred on the most important families, as it had actually developed.

    The other side wanted a more open council, in which able and deserving men, also from less central families, could participate. This was also like the council had developed. Even if the ancient and wealthy families dominated the council, there were many members from minor families.

    Several attempts at codifying the rules of membership of the Greater Council failed.

    In 1286, the Council of Forty suggested letting all descendants of recent members of the Greater Council enter the council automatically. The proposal would have made membership partially hereditary, thus guaranteeing certain families access, but not necessarily excluding others. It proposal didn’t pass.

    Another attempt to regulate the membership of the Greater Council was made in 1296, but that too failed to gather a majority.

    Then, in 1297, the doge suggested that membership should, limited to six months period, be extended to all those who had taken part in the council within the previous four years, to their descendants, and to those who had been eligible, but unable to participate because they’d been away from Venice.

    This limited proposal passed.

    Six months later, the following year, when the first law expired, a proposal to make it permanent passed the council.

    This is usually called the Serrata del Consiglio — the “Locking of the Council”.

    They, figuratively speaking, locked the doors of the Greater Council. No new families would enter, and no old families would leave. The doors were closed, and the discussion over.

    So who won this constitutional battle?

    It is not that clear-cut.

    Membership of the Greater Council became hereditary and limited to a well-defined circle of mostly wealthy families, which sounds like a restriction.

    However, the actual result of the “Locking of the Council” was a substantial widening of membership, up to a point where in the 1500s the council had over two thousand members.

    This reform did make Venice a fully aristocratic republic, where participation in the politics of the state was limited to certain families.

    The families, whose men by right of birth participated in the Greater Council, became the “nobles” or the “aristocracy,” and everybody else were variations of “citizens.”

    The Greater Council became where all major political matters were discussed and deliberated.

    War with the Pope

    The Republic of Venice went to war with the Papal state in 1308, over the possession of a fortress in Ferrara, which controlled an important crossing of the River Po.

    As always in Venetian history, when you scratch a bit at the surface, you find mercantile interests behind their actions.

    The Pope — Clement V, which Dante called “a lawless pastor” — furiously excommunicated Venice and all its citizens, and called for a crusade against the Venetians. The Doge — Pietro Gradenigo — responded, that “small children might be frighted by words, but men shouldn’t even be afraid of the points of swords.”

    Nevertheless, the war didn’t go well for Venice. The Venetian stronghold of Castel Tedaldo in Ferrara had to surrender, and the commander, Marco Querini, fled back to Venice.

    The conflict was eventually resolved by diplomatic means, and by paying a huge bribe to the Pope.

    Money achieved what arms had failed to obtain.

    The ruling elite in Venice — now organized in the Greater Council — was only ever united when there was an external threat to their collective control of the state. The normal state of affairs was one of ruthless in-fighting between factions for positions of power and status.

    This less than honourable outcome — and maybe more than that, the trauma of excommunication — led to a major split in the Venetian elite.

    A group of noblemen — around Baiamonte Tiepolo and Marco Querini — conspired to overthrow the faction of the doge.

    Baiamonte Tiepolo — great-grandson of a doge, grandson of a doge, whose father almost became a doge — was extremely ambitious and very wealthy, the scion of a Venetian dynasty.

    Marco Querini — from a family almost as ancient and important — was the commander who had abandoned the Castel Tedaldo in Ferrara during the war with the Pope.

    The Doge was, however, forewarned of the insurrection. As the conspirators approached the Doge’s palace from several directions, they were intercepted.

    The group led by Querini was defeated, and Marco Querini killed in the fight.

    Another group failed for reasons which have become legendary. The armed column proceeded through the alleyways towards the Doge’s Palace, following a standard-bearer, who showed the way.

    As they were about to enter the square, an old woman, from an upstairs window, dropped a stone mortar on the head of the standard-bearer.

    The man fell to the ground in a pool of blood, apparently struck dead from above, and the conspirators fled in disarray.

    Baiamonte Tiepolo hadn’t taken up arms himself, and was allowed to go into exile. The condition was that he didn’t seek refuge with any of the enemies of Venice. After some time, he did so anyway. He never returned to Venice.

    At the Rialto, two ancient arches are embedded in the modern building of the fish market. They were left standing as a monument of shame, when the palace of Marco Querini was demolished as part of the punishment of the conspirators.

    The Council of Ten

    The Greater Council, in an emergency assembly, elected a group of ten members to hunt down and kill the surviving conspirators, wherever they had fled.

    As was by then already an old tradition, such appointments were for short periods. In this case, with such a very specific task, for only two months. The task wasn’t finished after the first term, so it was extended for another two months, and another two, and then annually.

    Continuing in this way, the Council of Ten became a fixture of the Venetian state. The charges were gradually extended, to include any risk or danger to the security of the state, and it became the tribunal, where criminal cases against members of the nobility were heard.

    Every state excludes some people from the decision-making process, and therefore needs a repressive arm to keep dissent down. The Council of Ten became the repressive branch of the Venetian government.

    The Ten Councillors would be the most feared Venetian magistrates until the end of the Republic.

    The Black Plague

    The Black Plague — also called the Bubonic Plague — arrived in Venice at some point in 1347 or 1348.

    The plague originated somewhere in Central Asia, and arrived to the Black Sea through the ancient trade routes along the rivers.

    With the merchant ships prowling the Black Sea — which included Venetian and Genovese ships — it arrived in Constantinople, and from there to Venice and Genoa.

    Within five years, it had spread throughout all of Europe.

    Neither the Venetians nor anybody else, for that matter, had any kind of cure or treatment for the plague. They could do nothing but look on while people died in agony, and fear that they’d be next.

    Other waves of the plague hit Venice in 1361, 1371, 1374 and 1390, and they would continue well into the next century.

    There was an awareness that the plague arrived with the merchant ships, but so did the wealth that had made Venice powerful. As a society, Venice couldn’t — and wouldn’t — stop the ships.

    However, at the end of the 1300s, the population of Venice had halved. The economy was suffering due to a shortage of labour, but attempts at importing skilled labour led nowhere. People were dying all over Europe.

    The problem was becoming existential — a matter of survival, not just of persons, but of the state as such.

    Showdown with Genoa

    One of the many wars between Venice and Genoa almost took Venice off the map for good.

    A fleet from Genoa appeared in the upper Adriatic in 1379, and quickly took Chioggia, which is at the southern end of the Venetian lagoon.

    From there, the Genovese moved north, inside the lagoon, towards Venice. They established a forward base on the island of Poveglia, some ten kilometres south of Venice.

    The two navies fought for much of 1380, inside the lagoon, within sight of Venice itself.

    Venice — fighting for its very survival — threw everything it had into the fight, and in 1381 they dislodged the Genovese from Poveglia. Later that year, they took back Chioggia, and Genoa sued for peace.

    This war, just like the war against the Franks in 809, could have been the end of Venice.

    After this epic struggle, the Venetians started building defences in strategic places in the lagoon.

    The original citizens of Poveglia were never allowed back on the island again. It became a shipyard for the navy, a defensive structure, and, much later, a quarantine station for the plague.

  • Ascendency (1000–1200)

    Ascendency (1000–1200)

    Venice became a more important state in the 1000s and 1100s, and started to build not only their trading empire, but also more equal relations to the Byzantine Empire, the Holy Roman Empire and the Pope in Rome.

    Building on trade

    The Venetian elite were predominantly merchants, so securing international trading relations became a central function of the Venetian state.

    The conquest of Dalmatia was fragile, and the Venetians fought many wars to ensure their control of the main harbours. There were several rebellions in Dalmatian cities, where the locals clearly didn’t approve of their new Venetian overlords.

    However, Venice needed those cities and harbours.

    Medieval ships weren’t huge, and more commercial cargo meant less space in the hold for provisions. Venice therefore needed safe harbours along the Adriatic for their ships to resupply, and to seek shelter in bad conditions.

    They also needed to ensure that those harbours didn’t revert to being nests of pirates, as they had been in the past.

    While it wasn’t easy — nor without setbacks — Venice more or less kept the Dalmatian coast under its control.

    In 1082, the Byzantine emperor formally recognised the coast of Dalmatia as Venetian sphere of influence, and gave the doge the official title of Duke of Dalmatia.

    In the 1100s, the situation had partly changed, and some cities in the upper Adriatic actively sought Venetian stewardship. Venice had become the safer bet in an uncertain world, and a bringer of wealth through their ever wider trade networks.

    Byzantium and the Normans

    Further down the Adriatic, in Southern Italy, the Normans had replaced the Saracens as the shared nuisance of both Venice and Constantinople.

    The Normans had taken Apulia — the heel of the Italian boot — and thus became a threat to Byzantine territories in Greece and Albania, and to Venetian trade in and out of the Adriatic Sea.

    The relationship between Constantinople and Venice at this time looked more like an alliance of near peers, than between an empire and a marginal province.

    A weakened Byzantine Empire needed the Venetian navy in the Adriatic and around Southern Italy. Constantinople still had interests and claims there, but they were under increasing pressure and the empire had fewer resources to defend them.

    Venice, on the other side, needed the Byzantine Empire because that was where they did the most of their trade — the trade which was the basis for the power, wealth and status that Venice was building up.

    Mutual interests — as much as shared history and culture — had Constantinople and Venice fighting shared enemies.

    It was, however, a declining Byzantium and a Venice on the ascendancy.

    The Crusades

    The first crusade in 1099 had two purposes. One was to take back the Holy Land and Jerusalem from the Caliphate. The other was to give the Byzantine Empire a helping hand against the Seljuk Turks in Asia Minor.

    The mostly German and French crusader armies marched to Constantinople over land, and then across Anatolia to the Levant. The Venetians therefore didn’t have much of a role, and didn’t participate in any significant way.

    The crusade was a spectacular success on the first account — on taking back the Holy Land. A series of Latin crusader kingdoms soon dominated much of the Levant, from Antioch to Jerusalem.

    In terms of helping Byzantium against the Turks, the crusade was a failure, to say the least. If anything, it soured the relationship between the Byzantines and the crusaders, and, as crusaders travelled back to Western Europe, also with the western powers.

    For the Venetians and their trade, the upheaval of the power balance in the Levant caused plenty of problems.

    Many important harbours in the Levant were now under Latin rulers. The Venetians had frequented these harbours for centuries, and they had developed long-term relationships with the former rulers. Now they had to start all over.

    Furthermore, the new Latin rulers in the crusader kingdoms had more cultural affinity with some of the main competitors of Venice, such as Genoa and Catalonia. These quickly moved in to get a larger slice of the trade.

    As the antagonism between the crusader states and the Byzantine Empire grew, Venice also got caught up in that conflict.

    Nevertheless, Venice tried to navigate these turbulent waters, and with some success. In 1104, Venetian troops participated in the conquest of Acre, which became the main harbour of the Kingdom of Jerusalem. In 1110, Venice got part of the city, which they managed to keep into the 1180s.

    Early institutional reforms

    The Venetian state wasn’t planned, neither was Venetian statehood. It just kind of happened.

    Consequently, the early Venetian state was rather rudimentary. It was mostly the Doge and a few officials appointed to handle basic, practical tasks. The popular assembly — the Concio — only met whenever it was needed.

    The main problem was that the Doge, who was chosen for life, had too much power.

    In 1032, after the violent deposition of yet another doge, the election of the next doge got some strings attached. He could no longer appoint a co-ruler, and thereby influence the succession. There would be no more dynasties competing for the position of doge.

    The new doge also had to accept two councillors, who would partake in the decision process. These councillors were elected annually by the Concio.

    This was a significant change. It introduced checks on the power of the doge, who now had to confer and agree with the two councillors before taking any major decisions.

    The Concio, which until then had only met whenever there was an occasion, now had to meet annually to choose two new councillors for the doge. The hitherto rather informal assembly became an institution with regular meetings and procedures.

    These changes moved the Venetian state away from being that almost elective monarchy, which it had been from the earliest times.

    A proper capital

    Venice was, by the early 1100s, an important European state.

    It had also become one of the wealthiest cities in Europe — but it didn’t look like it yet.

    Already in 1050, the reconstruction of the Basilica of St Mark started, of a much larger and more monumental church. In 1053, Pope Leo IX visited Venice to venerate St Mark.

    Somehow, during the building of the new basilica, the Venetians managed to lose track of their greatest treasure, the bones of St Mark. By an incredible coincidence, they were miraculously relocated in 1094 for the inauguration of the basilica.

    Emperor Henry IV of the Holy Roman Empire came to Venice for the celebrations, and old treaties on mutual trade were reconfirmed.

    As discussed in the previous chapter, the relics of St Mark were important to Venice for much more than simple reasons of religion. The presence of the bones of the thirteenth apostle and author of one of the gospels, conferred a status on Venice, beyond what economic weight and military might could achieve alone.

    Venice needed shipyards for its navy, and had until the early 1100s relied on private shipyards to build what was needed. That proved insufficient, though. The state navy docks — the Arsenale — were established in 1104. They would become a fixture of life in the city, and the arsenalotti — workers from the Arsenale — later served as guard of honour and bodyguards for the doge and other state officials. The Arsenale is still there today, nine centuries later, now used by the Italian navy.

    Later, in the mid-1100s, the process of embellishment of the entire area of St Mark’s accelerated.

    Most of what is now the Piazza San Marco, belonged to the nuns of the nearby monastery of San Zaccaria. A canal — the Rio Batario — crossed the area, roughly in the middle of the current square. Beyond the canal, the nuns had an orchard with fruit trees — a brolo in Venetian.

    In the 1150s, the campanile — the bell tower — was built. It would get an important role in the daily life in Venice. The bells would regulate the working hours in the navy docks, the opening and closing hours of shops, the work of prostitutes and a special bell would summon the aristocracy to the palace when needed. It is, even today, affectionately called el paròn — the master who controlled time and labour.

    Sometimes around 1170, the nuns of San Zaccaria donated parts of their orchard to the state.

    The canal was filled in — the first known example of the removal of a city canal — and the square almost doubled in size. The square wasn’t paved then — that wouldn’t happen for another century.

    The Doge’s Palace was enlarged and the two columns on the waterfront raised, with the symbols of the two patron saints of the city and the state: St Mark and St Theodore.

    The first Rialto Bridge — a wooden drawbridge crossing the Grand Canal at the narrowest point — was also from this period.

    This monumentalization of the area of St Mark was the Venetian state dressing up, to make its looks match its increased wealth, power and international status.

    A great capital of a great nation is more than just buildings and structures. It is also great events and ceremonial.

    One such event was born in 1162.

    The invasion of the Lombards, centuries earlier, had caused the patriarch of Aquileia to flee into the lagoon at Grado, within the dogado. The Lombards chose their own patriarch, and thus there were two competing patriarchs, with about twenty kilometres between them.

    The head of the Catholic Church in the dogado was the Patriarch of Grado, while the Patriarchy of Aquileia developed into a semi-autonomous small state.

    The two never recognised each other, and in 1162 the Patriarch of Aquileia personally led his troops in an attack on the Patriarch of Grado in the lagoon.

    Venice intervened on behalf of their patriarch, and soundly defeated the forces of Aquileia, and captured the patriarch himself.

    He was taken to Venice, paraded through the city, and had to pay for his freedom with a promise of a tribute of a bull and twelve pigs, each year henceforth, for the carnival.

    This tribute was paid each year until the end of the Republic in 1797, and the commoners of Venice feasted on the slaughtered animals during the carnival. Nobody’s going to say no to a party and free food, so this tradition soon became very popular.

    Venice as peacemaker

    The new splendour of the palace, the church and the square all served Venice well, shortly after, in 1177.

    From the times of Charlemagne, most of Northern Italy had formed a Kingdom of Italy, which in the 1100s was formally part of the Holy Roman Empire.

    Many of the cities had, however, developed into semi-autonomous city states, of which Milan in Lombardy was the most important.

    When in the early 1160s, emperor Frederick Barbarossa tried to encroach on this de facto self-rule, the cities formed first the Lega Veronese, later extended into the Lega Lombarda, to fight for their autonomy.

    The Lega was not an independence movement — most cities were fine with being part of the empire, which had its advantages — but they wanted to handle local matters themselves.

    The Pope sided with the Lega, so this fight too became a part of the almost perpetual struggles between the Pope and the emperor.

    During the conflict, the Pope excommunicated the emperor, who in return appointed an anti-pope. Both sides tried to strike at the legitimacy of the other.

    The Lega won a decisive battle against an imperial army led by Barbarossa himself, at Pontida in 1176, and Barbarossa sued for terms afterwards.

    The details of those terms were negotiated in Venice in 1177.

    The Pope arrived in Venice in March that year, on war galleys from the navy of the Kingdom of Sicily. Barbarossa remained in Chioggia at the southern end of the lagoon, until an agreement had been reached.

    In July, Barbarossa arrived at San Nicolò on the Lido, and was accompanied to St Mark’s by the doge and the patriarch on a richly decorated Venetian war galley.

    The Pope and the emperor met in the Basilica of St Mark, where the final reconciliation took place.

    This was a huge win for Venetian diplomacy,

    The first war with Byzantium

    The relationship with Constantinople grew more complicated throughout the 1100s.

    Venice had for generations had special trading privileges in the Byzantine Empire, which, however, usually had to be confirmed by each new emperor.

    Emperor Alexios Komnenos issued an edict in 1082 giving the Venetians freedom from all taxes and tariffs, and access throughout the empire. These extended privileges were a reward for the help the Venetians had given the emperor fighting the Normans in Southern Italy.

    The Venetians used the trading agreements so efficiently, that they soon completely dominated trade in Constantinople, often to the detriment of indigenous Byzantine merchants, who couldn’t compete with the Venetians’ tariff-free trade.

    A sizeable Venetian population lived permanently in the imperial capital, and their wealth, the subsequent political influence — and supposedly also their arrogance — led to tension with the people of Constantinople, and at times to open conflict.

    When Alexios died in 1118, his son, John Komnenos II, became emperor.

    The Venetians promptly sent an emissary to Constantinople to request a renewal of the edict of 1082, but John refused.

    In response, Venice equipped a navy, commanded by doge Vitale Michiel, which attacked the island of Corfu unsuccessfully, and then raided the sea around Greece for several years.

    The Byzantines proved unable to stop the Venetians, and in 1126 John confirmed the privileges again, this time, however, with the addition that the Venetians in Constantinople had to behave better.

    For the first time ever, Venice had extracted privileges from Constantinople by use of force. The power balance between the two was not as clear-cut any more.

    A failed war with Byzantium

    Manuel Komnenos inherited this uneasy co-existence when he became emperor after his father in 1146.

    During the war of the Lega Lombarda, Manuel tried to win favour with other Italian nations, to have future allies against the Normans in Southern Italy.

    To gain their favour, he conceded trading privileges in the empire to Pisa and Genoa.

    Venice saw these concessions as an affront to their privileges, and complained.

    Manuel Komnenos responded by trying to stir up trouble for Venice in Dalmatia, which, however, a Venetian navy suppressed.

    At the start of 1171, the tension seemed to have subsided somewhat.

    However, a fire in the Genovese quarter in Constantinople was blamed on the Venetian residents, and Manuel used it as a pretext to order the arrest of all Venetians in the empire, and the confiscation of their property.

    When the news arrived in Venice, the Venetians were furious.

    During the summer, Venice built a navy of a hundred and twenty ships, which commanded by doge Vitale Michiel II set out for Constantinople in the autumn.

    When the navy arrived close to Athens, the Byzantine governor there offered peace negotiations. The talks dragged out, and the Venetian navy had to winter near a Greek island.

    The crowded and unsanitary conditions in the navy’s winter quarters caused an epidemic, and in early spring the fleet had to return to Venice, having achieved nothing.

    This debacle led to widespread dissent in Venice, and doge Vitale Michel II was murdered. He was the last doge to die as a result of a conspiracy.

    The political upheaval led to more institutional reforms.

    For the creation of a new doge, a Greater Council of several hundred members was chosen, shunting the older popular assembly of the Concio to the side.

    While the Concio had maintained the appearance that the election of the doge was by popular acclamation, with the explicit consent of the ruled, now the elite usurped that power. Only the upper class would now have any say in the creation of doges.

    Venice had become a more aristocratic republic.

    The massacre of the Latins

    Relations to Constantinople didn’t recover while Manuel Komnenos lived.

    The Venetian position in Constantinople deteriorated, and the influence of merchants from Pisa and Genoa grew.

    Manuel died in 1180, but his son Alexios II was a young child. A regency of his mother and an older cousin of Alexios, who was supposedly the lover of the dowager empress, took control of Constantinople.

    The regency emptied the imperial treasury, trying to curry favour with the important groups in Constantinople. The main beneficiaries were the great land-owners, mostly Byzantine, and the wealthy merchants, which were predominantly from Pisa and Genoa, even if were still many Venetians in Constantinople.

    The regency government was weak and unstable, and wars, conspiracies and suppression abounded.

    In 1182, a cousin of Manuel, Andronikos Komnenos, took control of the city. At his arrival, the celebrations quickly deteriorated into a pogrom against all Latins, who were rounded up and killed. The rage was such, that the Papal delegate to Constantinople was decapitated, and his severed head dragged around through the streets.

    There were an estimated sixty thousand Latins in Constantinople, mostly from Genoa, Pisa and Venice. Those, who weren’t killed or managed to flee the city in time, were sold into slavery to the Seljuk Turks.

    Andronikos was deposed in 1185, and a new imperial dynasty took over.

    Trade resumed because money matters, and the new rulers in Constantinople granted the Venetian renewed trading privileges in 1198, but the already strained relationship between east and west never recovered.

    The Fourth Crusade

    In 1202, a large Venetian fleet of over three hundred ships set out from Venice. Aboard were some fifteen hundred mostly French knights, about five thousand horses and almost thirty thousand soldiers. Their destination was the Holy Land, but they never got there.

    What they did do, shook the world. Neither the Byzantine Empire nor Venice would ever be the same again.
