During the Second Italo-Ethiopian War, the Italians captured and either imprisoned as prisoners of war or executed selected prominent Ethiopians. The majority of the public executions and mass incarcerations happened in the wake of the assassination attempt on Rodolfo Graziani. The Italian occupying force gave permission to the black shirts to murder educated Ethiopians, sparing only a few notables who were transported to various concentration camps maintained in the Harar region, Italian Somaliland, Eritrea and Italy. While the majority of prisoners who were kept at Asinara and other camps in Italy survived, tens of thousands of detainees perished under the severe conditions they were forced to live in. According to famous survivors like Ambassador Imru Zeleke, conditions were worse in Italian Somaliland camps due to the scarcity of food, water and medicine. According to Imru Zeleke, tens of thousands of Ethiopians died every year.
