Why was Italy dissatisfied after 1918?

Italy's dissatisfaction after 1918 stemmed from a combination of unmet expectations and internal problems following World War I.

1. Discontentment after the Treaty of Versailles : Italy could get only Southern Tyrol and Trentino, and the Coastal Regions of Dalmatia. She could get no part of the German and Turkish colonial empire.
2. Economic Crisis : Due to the expenses of World War I, Italy's national debt increased manifold, and people had to suffer for basic necessities like food and grains.
3. Weak Government and Political Instability : The people were greatly distressed due to the weak policies and inefficiency of the government, which was incapable of solving their problems. Since no single party could gain clear majority in the elections, there was complete instability after 1918.
4. Activities of the Socialists : The Socialists intensified tensions with their revolutionary ideas, while the Communists plotted to overthrow the government. Amid growing lawlessness and insecurity, people sought a strong party to restore peace and prosperity.
