 During the interwar period, the fascist Italian government undertook a campaign of Italianisation in the areas it annexed, which suppressed Slavic language, schools, political parties, and cultural institutions.During World War II, Italian war crimes included extrajudicial killings and ethnic cleansing by deportation of about 25,000 people, mainly Jews, Croats, and Slovenians, to the Italian concentration camps, such as Rab, Gonars, Monigo, Renicci di Anghiari and elsewhere.In Italy and Yugoslavia, unlike in Germany, few war crimes were prosecuted.
