Italia Irredenta (Unredeemed Italy) was an
Italian nationalist opinion movement that emerged after
Italian unification. It advocated
irredentism among the Italian people as well as other nationalities who were willing to become Italian and as a movement is also known as Italian irredentism. Not a formal organization, it was just an opinion movement that claimed that Italy had to reach its "natural borders". Similar patriotic and nationalistic ideas were common in Europe in the 19th century. Italian irredentism obtained an important result after
World War I, when Italy gained
Trieste,
Gorizia,
Istria and the city of
Zara (now
Zadar).
