Dalmatia
The Italian linguist Matteo Bartoli calculated that Italian was the primary spoken language by almost 30% of the Dalmatian population at the beginning of the Napoleonic wars. Bartoli's evaluation was followed by other claims: Auguste de Marmont, the French Governor General of the Napoleonic Illyrian Provinces commissioned a census in 1814–1815 which found that Dalmatian Italians comprised 25% of the total population of Dalmatia. Accordingly, three years later, an Austrian census found around 70,000 Italians in a total of 301,000 people living in Austrian Dalmatia.
With the development of Croatian nationalism, critics such as Croatian historian Duško Večerina, asserted that these evaluations were not conducted by modern scientific standards and that they took spoken language as the criterion, rather than ethnicity. They pointed out that, according to a report by Imperial court councillor Joseph Fölch in 1827, the Italian language was spoken by noblemen and some citizens of middle and lower classes exclusively in the coastal cities of Zara, Sebenico, and Spalato. Since only around 20,000 people populated these towns and not all were Italian speakers, their real number was rather smaller, probably around 7% of the total population, as is asserted by the Department of Historical Studies of the Croatian Academy of Sciences and Arts (HAZU).
Not only Italian irredentists (like Gabriele D'Annunzio) but also Italian prominent scholars (like Angelo Vivante) alleged that Joseph Fölch did not include the Dalmatian islands of Cres, Lošinj, Vis, Hvar, Korcula and many others islands with significant Italian communities. And so -in their opinion- Folch did only a partial and mistaken estimate of the real number of the Dalmatian Italians. They reasserted that the only official evidence about the Dalmatian population comes from the 1857 Austro-Hungarian census, which showed that in this year there were 369,310 indigenous Croatians and 45,000 Italians in Dalmatia, making Dalmatian Italians 17% of the total population of Dalmatia in the mid-19th century.
Dalmatia was a strategic region during World War I that both Italy and Serbia intended to seize from Austria-Hungary. Italy joined the Triple Entente Allies in 1915 upon agreeing to the London Pact that guaranteed Italy the right to annex a large portion of Dalmatia in exchange for Italy's participation on the Allied side. From 5-6 November 1918, Italian forces were reported to have reached Lissa, Lagosta, Sebenico, and other localities on the Dalmatian coast. By the end of hostilities in November 1918, the Italian military had seized control of the entire portion of Dalmatia that had been guaranteed to Italy by the London Pact and by 17 November had seized Fiume as well. In 1918, Admiral Enrico Millo declared himself Italy's Governor of Dalmatia. Famous Italian nationalist Gabriele d'Annunzio supported the seizure of Dalmatia, and proceeded to Zadar in an Italian warship in December 1918.
The last city with a significant Italian presence in Dalmatia was the city of Zadar (Zara). In the Habsburg empire census of 1910 the city of Zara had an Italian population of 9,318 (or 69.3% out of the total of 13,438 inhabitants). Zara population grew to 24,100 inhabitants, of which 20,300 Italians, when was in 1942 the capital of the Governatorate of Dalmatia (the "Governatorate" fulfilled the aspirations of the Italian irredentism in the Adriatic).
In 1943, Josip Broz Tito informed the Allies that Zara was a very important logistic centre for German forces in Yugoslavia. By overstating its importance, he persuaded them of its military significance. Italy surrendered in September 1943 and over the following year, specifically between 2 November 1943 and 31 October 1944, Allied Forces bombarded the town fifty-four times.
Nearly 2,000 people were buried beneath rubble; 10–12,000 people escaped and took refuge in Trieste and slightly over 1,000 reached Apulia.
Tito's partisans entered in Zara on 31 October 1944, and 138 people were killed. With the Peace Treaty of 1947, Italians still living in Zara followed the Italian exodus from Dalmatia and only about 100 Dalmatian Italians now remain in the city.
