Structural violence is a form of violence wherein some social structure or social institution may harm people by preventing them from meeting their basic needs.
The term was coined by Norwegian sociologist Johan Galtung, who introduced it in his 1969 article "Violence, Peace, and Peace Research". Some examples of structural violence as proposed by Galtung include institutionalized racism, sexism, and classism, among others. Structural violence and direct violence are said to be highly interdependent, including family violence, gender violence, hate crimes, racial violence, police violence, state violence, terrorism, and war. It is very closely linked to social injustice insofar as it affects people differently in various social structures.
According to Johan Galtung, rather than conveying a physical image, structural violence is an "avoidable impairment of fundamental human needs."
Galtung contrasts structural violence with "classical violence:" violence that is "direct," characterized by rudimentary, impermanent "bodily destruction" committed by some actor. Galtung places this as the first category of violence. In this sense, the purest form of structural violence can be understood as violence that endures with no particular beginning, and that lacks an 'actor' to have committed it.
Following this, by excluding the requirement of an identifiable actor from the classical definition of violence, Galtung lists poverty (i.e., the "deprival of basic human needs") as the second category of violence and "structurally conditioned poverty" as the first category of structural violence.
Asking why violence necessarily needs to be done to the human body for it to be considered violence—"why not also include violence done to the human mind, psyche or how one wants to express it"—Galtung proceeds to repression (i.e., the "deprival of human rights") as the third category of violence, and "structurally conditioned repression" (or, "repressive intolerance") as the second type of structural violence.
