What does state terrorism look like? How do we distinguish it from other forms of mass state violence, such as repression or genocide? Based on the developing literature on state terrorism, this study presents three expectations that violence perpetrated by the state should meet if it is to be classified as state terrorism: these are (a) that the violence is perpetrated by agents of the state, (b) that the violence is visible, and (c) that state terrorism focused against a state's own citizens will be carried out by an autocratic, personalistic regime. Drawing substantially on a series of primary sources, this study demonstrates that Idi Amin's regime in Uganda from 1971 to 1979 did engage in state terrorism against its own citizens.
