Trieste ( ;; ; ; ) is a city and seaport in northeast Italy. It is the capital and largest city of the autonomous region of Friuli-Venezia Giulia, as well as of the regional decentralization entity of Trieste. As of 2026, it has a population of 198,622, making it the 17th-largest city in Italy.
Trieste is located at the head of the Gulf of Trieste, on a narrow strip of Italian territory lying between the Adriatic Sea and Slovenia; Slovenia lies close, at approximately east and southeast of the city, while Croatia is about to the south of the city. The city has a long coastline and is surrounded by grassland, forest, and karstic areas.
Trieste belonged, as Triest, to the Habsburg monarchy from 1382 until 1918. In the 19th century, the monarchy was one of the Great Powers of Europe and Trieste was its most important seaport. As a prosperous trading hub in the Mediterranean region, Trieste grew to become the fourth largest city of the Austro-Hungarian Empire (after Vienna, Budapest, and Prague). At the turn of the 20th century, it emerged as an important hub for literature and music. Trieste underwent an economic revival during the 1930s, and the Free Territory of Trieste became a major site of the struggle between the Eastern and Western blocs after the Second World War.
A deep-water port, Trieste is a maritime gateway for northern Italy, Germany, Austria and Central Europe. It is considered the end point of the maritime Silk Road, with connections to the Mediterranean, Suez Canal and Atlantic Ocean. Since the 1960s, Trieste has emerged as a prominent research location in Europe because of its many international organisations and institutions. The city lies at the intersection of Latin (due to Italy), Slavic (due to Slovenia and Croatia) and Germanic (due to Austria) cultures, where Central Europe meets the Mediterranean Sea, and is home to diverse ethnic groups and religious communities.
A scholarly area, Trieste has the highest percentage of researchers, per capita, in Europe.G. Bar "Trieste, è record europeo di ricercatori: 37 ogni mille abitanti. Più della Finlandia", In: il Fatto Quotidiano, 26 April 2018. ("City of the Barcolana"), ("City of the bora"), ("City of Wind"), "Vienna by the sea" and "City of Coffee" are epithets used to describe Trieste.
Etymology
The most likely origin is the word Tergeste – with the -est- suffix typical of Venetic – derived from the hypothetical Illyrian word *terg- "market" (etymologically cognate to the Albanian term 'market, marketplace' and reconstructed Proto-Slavic "*tъrgъ"). Roman authors also transliterated the name as Tergestum (according to Strabo, the name of the oppidum Tergestum originated from the three battles the Roman Army had to engage in with local tribes, "TER GESTUM [BELLUM]").
History
Ancient history
Since the second millennium BC, the location was an inhabited site. Originally an Illyrian settlement, the Veneti entered the region in the 10th–9th c. BC and seem to have given the town its name, Tergeste, because terg* is a Venetic word meaning market (q.v. Oderzo, whose ancient name was Opitergium). Later, the town was captured by the Carni, a tribe of the Eastern Alps, before becoming part of the Roman Republic in 177 BC during the Second Istrian War.Bernardini, F., Vinci, G., Horvat, J., De Min, A., Forte, E., Furlani, S., Lenaz, D., Pipan, M., Zhao, W., Sgambati, A., Potleca, M., Micheli, R., Fragiacomo, A., & Tuniz, C. (2015). Early Roman military fortifications and the origin of Trieste, Italy. Proceedings of the National Academy of Sciences of the United States of America, 112(13), E1520–E1529.
After being attacked by barbarians from the interior in 52 BC, and until 46 BC, it was granted the status of Roman colony under Julius Caesar, who recorded its name as Tergeste in Commentarii de Bello Gallico (51 BC), in which he recounts events of the Gallic Wars. Roman Tergeste flourished due to its position on the road from Aquileia, the main Roman city in the area, to Istria, and as a port, some ruins of which are still visible. Emperor Augustus built a line of walls around the city in 33–32 BC, while Trajan built a theatre in the 2nd century. At the same time, the citizens of the town were enrolled in the tribe Pupinia. In 27 BC, Trieste was incorporated in Regio X of Augustan Italia.Giulipaola Ruaro, Strolling Around Trieste, (Trieste: Edizioni Fachin, 1986), 6
In the early Christian era Trieste continued to flourish. Between 138 and 161 AD, its territory was enlarged and nearby Carni and Catali were granted Roman citizenship by the Roman Senate and Emperor Antoninus Pius at the pleading of a leading Tergestine citizen, the quaestor urbanus, Fabius Severus.
Already at the time of the Roman Empire there was a fishing village called Vallicula ("small valley") in the Barcola area. Remains of richly decorated Roman villas, including wellness facilities, piers and extensive gardens suggest that Barcola was already a place for relaxation among the Romans because of its favourable microclimate, as it was located directly on the sea and protected from the bora. At that time, Pliny the Elder mentioned the vines of the wine Pulcino ("Vinum Pucinum" – probably today's "Prosecco"), which were grown on the slopes.Zeno Saracino: "Pompei in miniatura": la storia di "Vallicula" o Barcola. In: Trieste All News. 29 September 2018.
Middle Ages In 788, Trieste submitted to Charlemagne, who placed it under the authority of the count-bishop who in turn was subject to the Duke of Friùli.
During the 13th and 14th centuries, Trieste became a maritime trade rival to the Republic of Venice, which briefly occupied it in 1283–87, before coming under the patronage of the Patriarchate of Aquileia. After it committed a perceived offence against Venice, the Venetian State declared war against Trieste in July 1368 and by November had occupied the city. Venice intended to keep the city and began rebuilding its defences, but was forced to leave in 1372. Due to the Peace of Turin in 1381, Venice renounced its claim to Trieste and the leading citizens of Trieste petitioned Leopold III of Habsburg, Duke of Austria, to annex Trieste to his domains. The agreement of voluntary submission (dedizione) was signed at the castle of Graz on 30 September 1382.
The city maintained a high degree of autonomy under the Habsburgs, but was increasingly losing ground as a trade hub, both to Venice and to Ragusa. In 1463, a number of Istrian communities petitioned Venice to attack Trieste. Trieste was saved from utter ruin by the intervention of Pope Pius II who had previously been bishop of Trieste. However, Venice limited Trieste's territory to outside the city. Trieste would be assaulted again in 1468–1469 by Holy Roman Emperor Frederick III. His sack of the city is remembered as the "Destruction of Trieste".Giulipaola Ruaro, Strolling Around Trieste, (Trieste: Edizioni Fachin, 1986), 11 He then restored the city walls for the fourth time. Trieste was fortunate to be spared another sack in 1470 by the Ottomans who burned the village of Prosecco, only about from Trieste, while on their way to attack Friuli.
Early modern period
Following an unsuccessful Habsburg invasion of Venice in the prelude to the 1508–16 War of the League of Cambrai, the Venetians occupied Trieste again in 1508, and were allowed to keep the city under the terms of the peace treaty. However, the Habsburg Empire recovered Trieste a little over one year later, when the conflict resumed. By the 18th century Trieste became an important port and commercial hub for the Austrians. In 1719, it was granted status as a free port within the Habsburg Empire by Emperor Charles VI, and remained a free port until 1 July 1791. The reign of his successor, Maria Theresa of Austria, marked the beginning of a very prosperous era for the city. Serbs settled Trieste largely in the 18th and 19th centuries, and they soon formed an influential and rich community within the city, as a number of Serbian traders came into ownership of many important businesses and built palaces across Trieste.
19th century
In the following decades, Trieste was briefly occupied by troops of the French Empire during the Napoleonic Wars on several occasions, in 1797, 1805 and 1809. From 1809 to 1813, Trieste was annexed into the Illyrian Provinces, interrupting its status of free port and losing its autonomy. The municipal autonomy was not restored after the return of the city to the Austrian Empire in 1813. Following the Napoleonic Wars, Trieste continued to prosper as the Free Imperial City of Trieste (), a status that granted economic freedom, but limited its political self-government. The city's role as Austria's main trading port and shipbuilding centre was later emphasised by the foundation of the merchant shipping line Austrian Lloyd in 1836, whose headquarters stood at the corner of the Piazza Grande and Sanità (today's Piazza Unità d'Italia). By 1913, Austrian Lloyd had a fleet of 62 ships totalling 236,000 tonnes.Hubmann, Franz, & Wheatcroft, Andrew (editor), The Habsburg Empire, 1840–1916, London, 1972, With the introduction of constitutionalism in the Austrian Empire in 1860, the municipal autonomy of the city was restored, with Trieste becoming capital of the Austrian Littoral crown land ().
With anti-clericalism on the rise in the rest of the Italian peninsula due to the Kingdom of Piedmont-Sardinia's bellicose policies towards the church and its estates, Pope Leo XIII at times considered moving his residence to Trieste or Salzburg. However, Emperor Franz Joseph rejected the idea.Josef Schmidlin, Papstgeschichte der neueren Zeit, München, 1934, p.414 Trieste, along with Rijeka (Fiume), served as an important base for the Imperial-Royal Navy, which in the first decade of the 20th century embarked on a major modernisation programme. With the construction of the Austrian Southern Railway, the first major railway in the Empire, in 1857, Trieste acquired a significant role in the trade of coal.
Trieste had long been home to Italian irredentist sentiment, as evidenced by the activity at . In 1882 this fervour culminated in an attempted assassination of Emperor Franz Joseph at the hands of Wilhem Oberdank (Guglielmo Oberdan), while His Majesty was visiting the city. The perpetrator was arrested, tried, found guilty and ultimately sentenced to death. His legacy was regarded as worthy of martyrdom status by fellow irredentists, while monarchical elements regarded his actions as ignominious. The Emperor, who went on to reign for thirty-four more years, never again visited Trieste.
20th century At the beginning of the 20th century, Trieste was a bustling cosmopolitan city frequented by artists and philosophers. James Joyce was a long-stay tourist between 1904 and 1915. Joyce worked on Dubliners and Ulysses while in Trieste. His students included Italo Svevo, and a bookshop run by Umberto Saba was near Joyce's apartment. Other authors with roots in Trieste include Claudio Magris, Jan Morris, Fulvio Tomizza, Enzo Bettiza, Susanna Tamaro, and Ernesto Nathan Rogers. Sigmund Freud, Zofka Kveder, Dragotin Kette, Ivan Cankar, and Scipio Slataper have also been associated with Trieste. The city was the major port on the Austrian Riviera, a term used in tourist marketing.
World War I, annexation to Italy and Fascist era
Italy, in return for entering World War I on the side of the Allied Powers, had been promised substantial territorial gains, which included the former Austrian Littoral and western Inner Carniola. Italy therefore annexed the city of Trieste at the end of the war, in accordance with the provisions of the 1915 Treaty of London and the Italian-Yugoslav 1920 Treaty of Rapallo.
