Answer :

The main difference between the rebellion in Spain versus the rebellion in Italy was an issue of suppression. The Italians put down the uprising far quicker than the Spanish.

The correct answer is:

The new Spanish ruler seized power without popular support from citizens.

Between 1936 and 1975, Francisco Franco installed a totalitarian dictatorship. Franco had taken control of Spain with the Nationalist victory in the Spanish Civil War.

On the other hand, Benito Mussolini, the leader of the National Fascist Party, ruled Italy as Prime Minister from 1922 to 1943. He first led the country constitutionally, until 1925, when he abandoned the pretense of democracy and established a dictatorship.
