Which of the allies gained a little territory from from the old austro-Hungarian empire?

Italy gained territory from the former Austro-Hungarian Empire after World War I. The Treaty of Saint-Germain in 1919 awarded Italy areas such as South Tyrol, Trentino, and parts of Istria and Dalmatia. This expansion was part of Italy's ambitions to unify Italian-speaking populations and enhance its influence in the Adriatic region.
