End of Italian irredentism

Under the Treaty of Peace with Italy, 1947, Istria, Kvarner, most of the Julian March as well as the Dalmatian city of Zara was annexed by Yugoslavia causing the Istrian-Dalmatian exodus, which led to the emigration of between 230,000 and 350,000 of local ethnic Italians (Istrian Italians and Dalmatian Italians), the others being ethnic Slovenians, ethnic Croatians, and ethnic Istro-Romanians, choosing to maintain Italian citizenship.

The Istrian-Dalmatian exodus started in 1943 and ended completely only in 1960. According to the census organized in Croatia in 2001 and that organized in Slovenia in 2002, the Italians who remained in the former Yugoslavia amounted to 21,894 people (2,258 in Slovenia and 19,636 in Croatia).

After World War II, Italian irredentism disappeared along with the defeated Fascists and the Monarchy of the House of Savoy. After the Treaty of Paris (1947) and the Treaty of Osimo (1975), all territorial claims were abandoned by the Italian Republic (see Foreign relations of Italy). The Italian irredentist movement thus vanished from Italian politics. The 1947 Constitution of Italy established five autonomous regions (Sardinia, Friuli-Venezia Giulia, Sicily, Aosta Valley, and Trentino-Alto Adige/Südtirol), in recognition of their cultural and linguistic distinctiveness.
