This is Nabucco (first perfomed in 1842), by italian composer Verdi... Italians adopted it as a hymn of liberty and national unity during the process of unification...
It is widely assumed that the mondina song was modified and adopted as an anthem of the Italian partisans who opposed Nazism and fascism, and fought against the occupying forces of Nazi Germany, who were allied with the fascist and collaborationist Italian Social Republic between 1943 and 1945 during the Italian resistance and the liberation of Italy.
Versions of "Bella ciao" continue to be sung worldwide as a hymn of freedom and resistance.
