Explanation:
Totalitarianism can be defined as a form of centralized government that has an absolute control over the state. Thus, totalitarianism completely prohibits individual freedom, opposing ideologies, principles, political parties, and requires the people to be subservient to the state.
Simply stated, totalitarianism is an autocratic or dictatorial form of government.
An authoritarian government is also known as dictatorship and it can be defined as a type of government in which an individual who is a sole administrator is responsible for controlling, managing and directing the affairs of the particular country.
The world War I (WWI) was a period of battle between various countries from 1914 to 1918. It started formally on the 28th of July, 1914 and ended on the 11th of November, 1918.
In April 1915, Italy officially joined the World War I (WWI) and it was estimated that six hundred thousand (600,000) Italians died by the end of the war while several assets (properties) were completely destroyed.
Hence, the damage caused by World War I (WWI) to Italy's economy played the most important role in the rise of totalitarianism in Italy during the 20th century.
Benito Mussolini who was born on the 29th of July, 1883 in Varnano dei Costa, in Romagna became a fascist leader of Italy by gaining power through turmoil.
