Vittorio Orlando

Orlando represented Italy at the Paris Peace Conference as prime minister. He demanded the fulfillment of the Treaty of London, including Fiume and Dalmatia. President Wilson opposed these claims, leading to Orlando's walkout and eventual resignation in June 1919.

Orlando's successor signed the treaty that formally ended WWI with Austria. Italy gained Trentino, South Tyrol, and Istria, but not Fiume or Dalmatia. The perceived 'mutilated victory' fueled nationalist resentment and contributed to the rise of Fascism.
