Which tactic did both Josef Stalin and Benito Mussolini use to maintain control in their countries?

They both used manipulation and terror to destroy their opponents.

Explanation:

Mussolini gradually dismantled the institutions of democratic government and in 1925 made himself dictator, taking the title 'Il Duce'. He set about attempting to re-establish Italy as a great European power. The regime was held together by strong state control and Mussolini's cult of personality.

Stalin served as the General Secretary of the Central Committee of the Communist Party of the Soviet Union from 1922 until his death in 1953. In the years following the death of Vladimir Lenin, he rose to become dictator of the Soviet Union, using a combination of manipulation and terror to destroy his opposition.
