Yekatit 12

In 1937, two men in the Italian occupied Ethiopia tried to kill the Italian Viceroy. In response, the Italian army and Italian civilians went on a killing spree, burning down houses, and killing an estimated 20% of the population of Addis Ababa including sympathetic Ethiopians. Estimates of death range from 19,200 to 30,000 Ethiopian. Italy still downplays the massacre.
