Kingdom of Italy (1861–1946)
Before WW1, Italy was friends with the German Empire and Austria-Hungary. But Italy wanted parts of Austria-Hungary. In 1915, the United Kingdom promised the lands of South Tyrol, Istria and Dalmatia. But after Italy won WW1, they did not get all of the lands. In 1922, Benito Mussolini became Prime Minister. He was a fascist leader and didn't like Italy not getting all their promised land in WW1. He made Italy into a dictatorship without much liberty.
