Pisa


Pisa is a city and comune in Tuscany, Central Italy, straddling the Arno just before it empties into the Ligurian Sea. It is the capital city of the Province of Pisa. Although Pisa is known worldwide for the Leaning Tower of Pisa, the city contains more than twenty other historic churches, and several medieval and Renaissance palaces, mostly facing each other on the avenues along the Arno. Much of the city's architecture was financed from its history as one of the Italian maritime republics.
The city is also home to the University of Pisa, which has a history going back to the 12th century, the Scuola Normale Superiore di Pisa, founded by Napoleon in 1810, and its offshoot, the Sant'Anna School of Advanced Studies. Information statistics

History

Ancient times

Most believe the hypothesis that the origin of the name Pisa comes from Etruscan and means 'mouth', as Pisa is at the mouth of the Arno river.
Although throughout history there have been several uncertainties about the origin of the city of Pisa, excavations made in the 1980s and 1990s found numerous archaeological remains, including the fifth century BC tomb of an Etruscan prince, proving the Etruscan origin of the city, and its role as a maritime city, showing that it also maintained trade relations with other Mediterranean civilizations.
Ancient Roman authors referred to Pisa as an old city. Virgil, in his Aeneid, states that Pisa was already a great center by the times described; and gives the epithet of Alphēae to the city because it was said to have been founded by colonists from Pisa in Elis, near which the Alpheius river flowed. The Virgilian commentator Servius wrote that the Teuti founded the town 13 centuries before the start of the common era.
The maritime role of Pisa should have been already prominent if the ancient authorities ascribed to it the invention of the naval ram. Pisa took advantage of being the only port along the western coast between Genoa and Ostia. Pisa served as a base for Roman naval expeditions against Ligurians and Gauls. In 180 BC, it became a Roman colony under Roman law, as Portus Pisanus. In 89 BC, Portus Pisanus became a municipium. Emperor Augustus fortified the colony into an important port and changed the name to Colonia Iulia obsequens.
Pisa supposedly was founded on the shore, but due to the alluvial sediments from the Arno and the Serchio, whose mouth lies about north of the Arno's, the shore moved west. Strabo states that the city was away from the coast. Currently, it is located from the coast. However, it was a maritime city, with ships sailing up the Arno. In the 90s AD, a baths complex was built in the city.

Late Antiquity and Early Middle Ages

During the last years of the Western Roman Empire, Pisa did not decline as much as the other cities of Italy, probably due to the complexity of its river system and its consequent ease of defence. In the seventh century, Pisa helped Pope Gregory I by supplying numerous ships in his military expedition against the Byzantines of Ravenna : Pisa was the sole Byzantine centre of Tuscia to fall peacefully in Lombard hands, through assimilation with the neighbouring region where their trading interests were prevalent. Pisa began in this way its rise to the role of main port of the Upper Tyrrhenian Sea and became the main trading centre between Tuscany and Corsica, Sardinia, and the southern coasts of France and Spain.
After Charlemagne had defeated the Lombards under the command of Desiderius in 774, Pisa went through a crisis, but soon recovered. Politically, it became part of the duchy of Lucca. In 860, Pisa was captured by vikings led by Björn Ironside. In 930, Pisa became the county centre within the mark of Tuscia. Lucca was the capital but Pisa was the most important city, as in the middle of tenth century Liutprand of Cremona, bishop of Cremona, called Pisa Tusciae provinciae caput, and a century later, the marquis of Tuscia was commonly referred to as "marquis of Pisa". In 1003, Pisa was the protagonist of the first communal war in Italy, against Lucca. From the naval point of view, since the ninth century, the emergence of the Saracen pirates prompted the city to expand its fleet. In the following years, this fleet gave the town an opportunity for more expansion. In 828, Pisan ships assaulted the coast of North Africa. In 871, they took part in the defence of Salerno from the Saracens. In 970, they gave also strong support to Otto I's expedition, defeating a Byzantine fleet in front of Calabrese coasts.

11th century

The power of Pisa as a maritime nation began to grow and reached its apex in the 11th century, when it acquired traditional fame as one of the four main historical maritime republics of Italy.
At that time, the city was a very important commercial centre and controlled a significant Mediterranean merchant fleet and navy. It expanded its powers in 1005 through the sack of Reggio Calabria in the south of Italy. Pisa, which was attacked in 1011, was in continuous conflict with some 'Saracens' - a medieval term to refer to Arab Muslims - who had their bases in Corsica. In 1017, Sardinian Giudicati were militarily supported by Pisa, in alliance with Genoa, to defeat the Saracen King Mugahid, who had settled a logistic base in the north of Sardinia the year before. This victory gave Pisa supremacy in the Tyrrhenian Sea. When the Pisans subsequently ousted the Genoese from Sardinia, a new conflict and rivalry was born between these major marine republics. Between 1030 and 1035, Pisa went on to defeat several rival towns in Sicily and conquer Carthage in North Africa. In 1051–1052, the admiral Jacopo Ciurini conquered Corsica, provoking more resentment from the Genoese. In 1063, Admiral Giovanni Orlandi, coming to the aid of the Norman Roger I, took Palermo from the Saracen pirates. The gold treasure taken from the Saracens in Palermo allowed the Pisans to start the building of their cathedral and the other monuments which constitute the famous Piazza del Duomo, Pisa.
In 1060, Pisa engaged in its first battle with Genoa. The Pisan victory helped to consolidate its position in the Mediterranean. Pope Gregory VII recognised in 1077 the new "Laws and customs of the sea" instituted by the Pisans, and in 1081 Emperor Henry IV recognized their communal government. This was simply a confirmation of the present situation, because in those years, the marquis had already been excluded from power. In 1092, Pope Urban II awarded Pisa the supremacy over Corsica and Sardinia, and at the same time raising the town to the rank of archbishopric.
The Pisan fleet captured the Zirid city of Mahdia in 1087, securing a ransom from its ruler. Four years later, Pisan and Genoese ships helped Alfonso VI of Castilla to push El Cid out of Valencia. A Pisan fleet of 120 ships also took part in the First Crusade, and the Pisans were instrumental in the taking of Jerusalem in 1099. On their way to the Holy Land, the ships did not miss the occasion to sack some Byzantine islands; the Pisan crusaders were led by their archbishop Daibert, the future patriarch of Jerusalem. Pisa and the other Repubbliche Marinare took advantage of the crusade to establish trading posts and colonies in the Eastern coastal cities of the Levant. In particular, the Pisans founded colonies in Antiochia, Acre, Jaffa, Tripoli, Tyre, Latakia, and Accone. They also had other possessions in Jerusalem and Caesarea, plus smaller colonies in Cairo, Alexandria, and of course Constantinople, where the Byzantine Emperor Alexius I Comnenus granted them special mooring and trading rights. In all these cities, the Pisans were granted privileges and immunity from taxation, but had to contribute to the defence in case of attack. In the 12th century, the Pisan quarter in the eastern part of Constantinople had grown to 1,000 people. For some years of that century, Pisa was the most prominent commercial and military ally of the Byzantine Empire, overcoming Venice itself.

12th century

In 1113, Pisa and Pope Paschal II set up, together with the count of Barcelona and other contingents from Provence and Italy, a war to free the Balearic Islands from the Moors; the queen and the king of Mallorca were brought in chains to Tuscany. Though the Almoravides soon reconquered the island, the booty taken helped the Pisans in their magnificent programme of buildings, especially the cathedral, and Pisa gained a role of pre-eminence in the Western Mediterranean.
In the following years, the powerful Pisan fleet, led by archbishop Pietro Moriconi, drove away the Saracens after ferocious battles. Though short-lived, this Pisan success in Spain increased the rivalry with Genoa. Pisa's trade with Languedoc, Provence were an obstacle to Genoese interests in cities such as Hyères, Fos, Antibes, and Marseille.
The war began in 1119 when the Genoese attacked several galleys on their way home to the motherland, and lasted until 1133. The two cities fought each other on land and at sea, but hostilities were limited to raids and pirate-like assaults.
In June 1135, Bernard of Clairvaux took a leading part in the Council of Pisa, asserting the claims of Pope Innocent II against those of Pope Anacletus II, who had been elected pope in 1130 with Norman support, but was not recognised outside Rome. Innocent II resolved the conflict with Genoa, establishing Pisan and Genoese spheres of influence. Pisa could then, unhindered by Genoa, participate in the conflict of Innocent II against king Roger II of Sicily. Amalfi, one of the maritime republics, was conquered on August 6, 1136; the Pisans destroyed the ships in the port, assaulted the castles in the surrounding areas, and drove back an army sent by Roger from Aversa. This victory brought Pisa to the peak of its power and to a standing equal to Venice. Two years later, its soldiers sacked Salerno.
In the following years, Pisa was one of the staunchest supporters of the Ghibelline party. This was much appreciated by Frederick I. He issued in 1162 and 1165 two important documents, with these grants: Apart from the jurisdiction over the Pisan countryside, the Pisans were granted freedom of trade in the whole empire, the coast from Civitavecchia to Portovenere, a half of Palermo, Messina, Salerno and Naples, the whole of Gaeta, Mazara, and Trapani, and a street with houses for its merchants in every city of the Kingdom of Sicily. Some of these grants were later confirmed by Henry VI, Otto IV, and Frederick II. They marked the apex of Pisa's power, but also spurred the resentment of other cities such as Lucca, Massa, Volterra, and Florence, thwarting their aim to expand towards the sea. The clash with Lucca also concerned the possession of the castle of Montignoso and mainly the control of the Via Francigena, the main trade route between Rome and France. Last, but not least, such a sudden and large increase of power by Pisa could only lead to another war with Genoa.
Genoa had acquired a dominant position in the markets of southern France. The war began in 1165 on the Rhône, when an attack on a convoy, directed to some Pisan trade centres on the river, by the Genoese and their ally, the count of Toulouse, failed. Pisa, though, was allied to Provence. The war continued until 1175 without significant victories. Another point of attrition was Sicily, where both the cities had privileges granted by Henry VI. In 1192, Pisa managed to conquer Messina. This episode was followed by a series of battles culminating in the Genoese conquest of Syracuse in 1204. Later, the trading posts in Sicily were lost when the new Pope Innocent III, though removing the excommunication cast over Pisa by his predecessor Celestine III, allied himself with the Guelph League of Tuscany, led by Florence. Soon, he stipulated a pact with Genoa, too, further weakening the Pisan presence in southern Italy.
To counter the Genoese predominance in the southern Tyrrhenian Sea, Pisa strengthened its relationship with its traditional Spanish and French bases and tried to defy the Venetian rule of the Adriatic Sea. In 1180, the two cities agreed to a nonaggression treaty in the Tyrrhenian and the Adriatic, but the death of Emperor Manuel Comnenus in Constantinople changed the situation. Soon, attacks on Venetian convoys were made. Pisa signed trade and political pacts with Ancona, Pula, Zara, Split, and Brindisi; in 1195, a Pisan fleet reached Pola to defend its independence from Venice, but the Serenissima soon reconquered the rebel sea town.
One year later, the two cities signed a peace treaty, which resulted in favourable conditions for Pisa, but in 1199, the Pisans violated it by blockading the port of Brindisi in Apulia. In the following naval battle, they were defeated by the Venetians. The war that followed ended in 1206 with a treaty in which Pisa gave up all its hopes to expand in the Adriatic, though it maintained the trading posts it had established in the area. From that point on, the two cities were united against the rising power of Genoa and sometimes collaborated to increase the trading benefits in Constantinople.
