When "symbols of Cambodian society were equally disrupted, social institutions of every kind…were purged or torn down", cultural violence (defined as when "any aspect of culture such as language, religion, ideology, art, or cosmology is used to legitimize direct or structural violence") is added to the structural violence of forced movement and to the direct violence, such as murder, at the Killing Fields. Vietnam eventually intervened and the genocide officially ended. However, ten million landmines left by opposing guerillas in the 1970s continue to create a violent landscape in Cambodia. Human geography, though coming late to the theorizing table, has tackled violence through many lenses, including anarchist geography, feminist geography, Marxist geography, political geography, and critical geography. However, Adriana Cavarero notes that, "as violence spreads and assumes unheard-of forms, it becomes difficult to name in contemporary language". Cavarero proposes that, in facing such a truth, it is prudent to reconsider violence as "horrorism"; that is, "as though ideally all the…victims, instead of their killers, ought to determine the name". With geography often adding the forgotten spatial aspect to theories of social science, rather than creating them solely within the discipline, it seems that the self-reflexive contemporary geography of today may have an extremely important place in this current (re)imaging of violence, exemplified by Cavarero. Epidemiology
As of 2010, all forms of violence resulted in about 1.34 million deaths up from about 1 million in 1990. Suicide accounts for about 883,000, interpersonal violence for 456,000 and collective violence for 18,000.
The trend, starting in archaeology and spreading to anthropology reached its height in the late half of the 20th century. However, some newer research in archaeology and bioarchaeology may provide evidence that violence within and among groups is not a recent phenomenon. According to the book "The Bioarchaeology of Violence" violence is a behavior that is found throughout human history.Lawrence H. Keeley at the University of Illinois writes in War Before Civilization that 87% of tribal societies were at war more than once per year, and that 65% of them were fighting continuously. He writes that the attrition rate of numerous close-quarter clashes, which characterize endemic warfare, produces casualty rates of up to 60%, compared to 1% of the combatants as is typical in modern warfare. "Primitive Warfare" of these small groups or tribes was driven by the basic need for sustenance and violent competition.Fry explores Keeleys argument in depth and counters that such sources erroneously focus on the ethnography of hunters and gatherers in the present, whose culture and values have been infiltrated externally by modern civilization, rather than the actual archaeological record spanning some two million years of human existence. Fry determines that all present ethnographically studied tribal societies, "by the very fact of having been described and published by anthropologists, have been irrevocably impacted by history and modern colonial nation states" and that "many have been affected by state societies for at least 5000 years. "The relatively peaceful period since World War II is known as the Long Peace.
