Step-by-step explanation:
The conquests made by Italy after World War 1 angered other nations due to territorial disputes and concerns over Italian expansionism. One significant example is the acquisition of territories such as Fiume (now Rijeka) and Dalmatia, which were originally promised to Yugoslavia under the Treaty of London but were claimed by Italy. This sparked tensions and led to diplomatic conflicts between Italy and Yugoslavia.
Furthermore, Italy's annexation of Libya and the Dodecanese Islands in the Mediterranean also raised concerns among other nations. These actions by Italy were seen as imperialistic and a violation of the principle of self-determination.
The aggression of Italy's conquests after WW1 contributed to the rising tensions and rivalries in Europe, which eventually led to the outbreak of World War 2.
