One of the primary components of state stability and order is that citizens consider those in power just and legitimate. Citizens who perceive the state as legitimate are likely to consider its institutions a valid source of morality and social control. Theoretically, legitimacy should play an important role in criminal offending across countries. This link between state power and citizens—that is, legitimacy—has the potential to be an important social mechanism connecting state actions to individual criminal behaviours. With this in mind, this article explores how political legitimacy might affect levels of crime and violence across countries. A lack of legitimacy may lead citizens to (1) reject the monopoly of physical force to employ self-help and/or (2) withdraw commitment from institutions, breaking down social control.
