Trieste under French Rule: the Sixteen Napoleonic Years (1797-1813)

Between 1797 and 1813, Trieste experienced the most turbulent chapter of its modern history. The commercial heart and free port of the Habsburg Empire was occupied three times by Napoleonic troops, was annexed to a French governorate centred on Ljubljana, hosted in exile half of Bonaparte's family — and finally returned to Vienna only after a siege of the Castello di San Giusto. Sixteen years that disrupted the Theresian prosperity of the city but laid down, paradoxically, some of the symbols still visible today.

A free port at the centre of the Napoleonic wars

Trieste before 1797

At the end of the eighteenth century, Trieste was the principal port of the Austrian Empire: an autonomous Free Port (porto franco) granted by Charles VI in 1719 and consolidated by Maria Theresa, with privileges that made it competitive with Hamburg or Genoa. The city was multilingual, multi-religious, mercantile — and almost defenceless from a military point of view. The fifteenth-century Castello di San Giusto had long ceased to be a serious fortress.

Why Napoleon arrived

After the Italian Campaign of 1796-1797, the young general Bonaparte defeated the Austrians in northern Italy and pushed eastward. The Habsburgs hastily negotiated the preliminaries of Leoben (18 April 1797) and Trieste, undefended, opened its gates to the French.

The first occupation: Napoleon at Palazzo Brigido (April 1797)

A single day in the city

On 29 April 1797 Napoleon Bonaparte personally entered Trieste. He stayed at the Palazzo Brigido, residence of the Austrian governor Pompeo, Count of Brigido. It was the only visit the future emperor would ever pay to the city.

The 20,000-florin levy

Napoleon imposed on Trieste a war indemnity of 20,000 florins, partly mitigated through the diplomatic skills of local elites. The first French occupation lasted only weeks: on 24 May 1797 the French army withdrew following the Leoben terms, and Count Brigido returned to govern the city. The Treaty of Campoformio (17 October 1797) sealed the first restoration of Austrian sovereignty.

Austerlitz and the second occupation (1805-1806)

Eight years later, the Third Coalition War brought the French back. After the catastrophic defeat at Austerlitz (2 December 1805) and the Peace of Pressburg (26 December 1805), Trieste was occupied for the second time, from late 1805 to the summer of 1806. The city returned again to Austrian administration, but the writing was on the wall: Napoleon's expansion to the Adriatic was no longer just an episode.

The Illyrian Provinces (1809-1813)

The Treaty of Schönbrunn

The third and decisive French occupation began on 19 May 1809. With the Treaty of Schönbrunn (14 October 1809) Napoleon detached from the Habsburg Empire an enormous territorial belt — Carinthia, Carniola, Istria, Dalmatia, Croatia, the Triestine littoral, Trieste itself — and grouped it together into a new political entity: the Illyrian Provinces (Provinces illyriennes), with its capital at Ljubljana (Laibach). For the first time in centuries, Trieste was no longer the heart of an empire but the seaport of a French governorate.

The four governors-general

The Illyrian Provinces had four governors-general in less than four years:

• Auguste de Marmont (8 October 1809 – January 1811), Marshal of France
• Henri-Gatien Bertrand (9 April 1811 – 21 February 1813), grand marshal of the imperial palace
• Jean-Andoche Junot (21 February – July 1813), already disturbed in mind
• Joseph Fouché (June – October 1813), the inventor of modern political police

Each had a personal connection to Napoleon and exercised power directly through Trieste, even though the official capital remained Ljubljana.

Trieste, 'Winter Capital' of Illyria

From 1810 onward, Trieste functioned as the de facto winter capital of the Illyrian Provinces, hosting the governors during the cold months and acting as logistical hub for trade. But the free port was suspended and the Napoleonic continental blockade strangled commerce: rich merchant houses moved to Vienna or Genoa, unemployment exploded among port workers, the population contracted. The French left to Trieste streets, decrees and écoles centrales — but took away its economic monopoly.

The Siege of Trieste (October-November 1813)

The Sixth Coalition arrives

In August 1813 Austrian troops under General Franz Tomassich invaded the Illyrian Provinces. On 12 October 1813 Field Marshal Laval Nugent von Westmeath appeared in view of the city, supported from the sea by the British naval squadron of Admiral Thomas Fremantle. The siege had begun.

Asymmetric forces

• Anglo-Austrian besiegers: about 3,500 men
• Franco-Italian garrison: no more than 800, commanded by a certain Colonel Rabie, entrenched in the Castello di San Giusto

The fifteenth-century castle was militarily obsolete. Cannon balls struck its walls — among the very few combat episodes in its long history. The British fleet bombarded from the sea.

Capitulation (2 November 1813)

After three weeks of resistance, the French capitulated on 2 November 1813. The numbers tell the story: 63 dead or wounded among the besiegers, around 150 dead and 641 prisoners in the French garrison. The Habsburgs immediately re-established Trieste's free port — the city's true raison d'être.

Two squares for two victories

From Franciscan convent to Piazza Lützen

The most visible Napoleonic mark on the city is what is today Piazza Hortis. Until 1796 it housed the medieval Franciscan convent founded in 1229 and suppressed in 1783 by Joseph II. The French demolished its remains in 1813 on the orders of Baron Angelo Calafatti, creating a tree-lined square named Piazza Lützen to commemorate Napoleon's victory of 2 May 1813.

From Lipsia to Hortis

By the end of that same year, with French withdrawal, the square was renamed Piazza Lipsia (Leipzig) — celebrating the Battle of the Nations of 16-19 October 1813, which had crushed Napoleon. Subsequent renamings led through Piazza delle Scuole to today's Piazza Attilio Hortis, in memory of the Triestine philologist.

The Bonapartes in exile (1814-1830)

A family in flight

In a paradox of European history, the fall of Napoleon transformed Trieste into a refuge for the Napoleonids — members of the imperial family tolerated by the Habsburgs and watched by Austrian police. Three Bonapartes and one of their most formidable servants ended their political lives along the Adriatic.

Girolamo Bonaparte at Palazzo Romano

Girolamo Bonaparte, former King of Westphalia, and his wife Caterina di Württemberg arrived in Trieste in 1814 disguised under the names of Count and Countess of Harz. He bought from Pietro Antonio Romano the Palazzo Romano, a neoclassical building with a Pompeian rotunda overlooking the sea, on what is today via Diaz 19 (demolished in 1936). On the night of 24 March 1815, days after Napoleon's escape from Elba, Girolamo and his retinue slipped out of the palace disguised as sailors and crossed the Adriatic to Ancona to join the emperor for the Hundred Days.

Elisa Baciocchi and Villa Murat

Elisa Bonaparte Baciocchi, eldest sister of Napoleon and former Grand Duchess of Tuscany, came to Trieste in 1814 with her husband Felice Pasquale Baciocchi. Around 1816 the couple purchased the villa on the Sant'Andrea hill that would later be called Villa Murat; Felice added two wings, a carriage house and a chapel. Elisa died in 1820, still in Trieste.

Caroline Bonaparte Murat, Countess of Lipona

Caroline Bonaparte Murat, sister of Napoleon and widow of Gioacchino Murat (executed in 1815), fled to the Austrian Empire after the Hundred Days. Settling in Trieste in 1823, she took the title of Contessa di Lipona — an anagram of Napoli. She inherited the Baciocchi villa, renamed it Villa Murat, and lived there in retirement, devoted to books and painting, until 1830, when she moved to Florence. She died in 1839 at the age of 57; the villa was demolished in 1899, leaving only the terrace of Passaggio Sant'Andrea.

Fouché, the chief of police, dies in exile

Joseph Fouché, Duke of Otranto and last governor of the Illyrian Provinces, was expelled by Louis XVIII in 1816 and rejected by all the courts of Europe. He obtained Austrian citizenship in 1819 and settled permanently at Palazzo Vicco, today the seat of the Archbishopric. He died there on 26 December 1820 of lung disease and was buried in the Cathedral of San Giusto. The inventor of modern political police ended his days, ironically, watched by the same Austrian police he had taught Europe to fear.

Prince Napoleon ('Plon-Plon') is born at Villa Necker

In 1822 at Villa Necker, Girolamo Bonaparte's son was born — Prince Napoleon Joseph Charles Paul, nicknamed Plon-Plon — future protagonist of the Italian Risorgimento, husband of Princess Clotilde of Savoy and a key political figure of the Second French Empire.

The legacy

Economic wound, political acceleration

The Napoleonic episode was a deep economic wound for Trieste: the suspension of the free port, the continental blockade and the wars halved commercial activity. But it was also a catalyst of modernity. The French introduced the Code Civil, secular state administration, public schools (écoles centrales), road improvements; they accustomed the local elite to thinking in European and not just Habsburg terms.

The unintended cosmopolitan capital

The presence of the Napoleonids — Girolamo, Carolina, Elisa, Fouché and many others — turned post-1815 Trieste into a melancholy capital of defeated empires. Their salons, their books, their carriages, their children born on Adriatic terraces all added a layer to the city's cosmopolitan stratification — alongside the Habsburg merchants, the Greek shipowners, the Jewish bankers.

What we can still see

Today, walking through Piazza Hortis, climbing to the Castello di San Giusto, passing in front of the Arcivescovado in via Cavana, we are stepping through the unintended monuments of Napoleonic Trieste. The free port, restored by the Habsburgs in 1813 and active until 1891, would propel the city to its imperial apogee — but its foundations had been shaken by sixteen French years.
