Structural violence, a term which was first used in the 1960s and which has commonly been ascribed to Johan Galtung, denotes a form of violence which corresponds with the systematic ways in which a given social structure or social institution kills people slowly by preventing them from meeting their basic needs. Institutionalized elitism, ethnocentrism, classism, racism, sexism, adultism, nationalism, heterosexism and ageism are just some examples of structural violence. Life spans are reduced when people are socially dominated, politically oppressed, or economically exploited. Structural violence and direct violence are highly interdependent. Structural violence inevitably produces conflict and often direct violence, including family violence, racial violence, hate crimes, terrorism, genocide, and war.
