This paper makes two claims, one empirical and the other theoretical. The empirical claim is that violence has become more private over time, building on the finding that violence in European societies has declined many times over during the past 1,000 years or so. The present-theoretical claim extends to earlier, premodern societies where violence may or may not be frequent. In premodern settings, most violence involves groups and parties who are not intimate with one another. The long process of modernization brings large declines in the incidence of collective and nonintimate violence. The violence remaining is, overall, less public and more private; meaning violence has privatized. Drawing on research conducted in 1976 and 1993, the Blackian theory of privatization, this paper proposes that as intimate social ties weakened and the state strengthened, collective and nonintimate forms of (nonpolitical) violence declined significantly; consequently, violence increasingly became less public, more private. However, other factors, such as the birth of a scientific rationalist worldview, the growth of urbanization, the development of capitalism, and the emergence of industrialization could be responsible for the privatization of violence, thereby requiring further inquiry into the validity of these proposals.
