Historians’ treatment of violence has been dominated by a binary theoretical orientation. A critique of this outlook leads to articulating a new, three-part model of violence as a cultural history problem. Neither functionalist readings in terms of power nor interpretations in terms of signification sufficiently explain violence: it is proposed that risk operates as a bridging category, bringing out the unique features violence introduces to the general social contest over domination and meaning. This chapter details the insights drawn from three key risk analysis theories—prospect theory, edgework, and the calculus of jeopardy—to model risk as a dimension of violence. It defines key concepts used throughout the book: violence (‘forceful physical action apt to cause harm’), power, signification, and risk, as well as risk magnitude, likelihood, realms, and domains
