Benito Mussolini
"Benito Amilcare Andrea Mussolini[a] (29 July 1883 – 28 April 1945) was an Italian dictator who founded and led the National Fascist Party (PNF). He was Prime Minister of Italy from the March on Rome in 1922, until his deposition in 1943, as well as Duce of Italian fascism from the establishment of the Italian Fasces of Combat in 1919, until his execution in 1945. As a dictator and founder of fascism, Mussolini inspired the international spread of fascist movements during the interwar period."1
Here is just one example of the effects of his leadership. See the links for more: "In 1923, Benito Mussolini embarked upon a pacification of Libya campaign to consolidate control over the Italian territory of Libya and Italian forces began to occupy large areas of Libya in order to allow Italian colonists to rapidly settle in it. They were met with resistance by the Senussi who were led by Omar Mukhtar. Civilians suspected of collaboration with the Senussi were executed. Refugees from the fighting were subject to bombing and strafing by Italian aircraft. In 1930, in northern Cyrenaica, 20,000 Bedouins were relocated and their land was given to Italian settlers. The Bedouins were forced to march across the desert into concentration camps. Starvation and other poor conditions in the camps were rampant and the internees were used for forced labour, ultimately leading to the death of nearly 4,000 internees by the time they were closed in September 1933. Over 80,000 Cyrenaicans died during the Pacification in all."2
