Mussolini, the prime minister of Italy during the times of war and also the leader of the National Fascist Party, gained support before arriving at the power by stimulating a nationalist sentiment promising to restore the former glory of the Roman Empire. This was why when he arrived at the power at first by the democratic ways and then establishing a dictatorship began with an aggressive military expansion.
He saw the foreign relations as a Social Darwinism struggle and considered that the future rulers of Europe would be Germany and Italy because of their high birth rates. So he made an alliance with Hitler´s Germany.
To summon it up what motivated Italy´s policy of aggressive military expansion was the desire of the Mussolini and the National Fascist Party to restore the power Italy used to have during the times of the Roman Empire.
I hope this answer helps.
