28 What is the main factor that contributed Fascism to rise in Italy
Following factors led to rise of fascism in Italy :-
1. Soaring unemployment
2. Rising price of articles of daily use.
3. The people were fed up with the various political
factions in Italy who were incessantly fighting amongst each other for their vested interests rather than providing
stability to the nation through a mature and responsible leadership.
These 3 factors along with feelings of nationalism and
injustice done to Italy during World War I vis-a-vis denying her share in territorial possessions (Treaty of Versailles clause) paved the path for rise of fascism in Italy. Mussolini’s dictatorial ideology provided a rallying point for the people who gave their full-fledged support ot him and threw their weight behind the fascist party.
All these factors helped Mussolini to effectively emerge as the sole powerful party in Italy. After coming to power, he systematically eliminated all those people/parties who opposed his views/ideas.
It needs to be noted that the rise of fascists in Italy was similar to that of Nazis in Germany as in both countries,
the socio-politico-economic situation was same and the Nazis and Fascists exploited these conditions to their favour and rose to power.
