War Before Civilization

War Before Civilization: The Myth of the Peaceful Savage is a 1996 book by Lawrence H. Keeley, published by , that examines archaeological and ethnographic evidence to argue that warfare was widespread, frequent, and proportionally more lethal in prehistoric and non-state societies than commonly portrayed in academic and popular narratives. Keeley contends that the notion of pre-civilized humans as peaceful "noble savages" stems from selective interpretation of data and ideological preferences rather than empirical findings, drawing on skeletal remains showing high rates of violent , fortified settlements, and mass graves from through periods. The book quantifies prehistoric warfare's intensity, estimating casualty rates from combat at 10-60% in some tribal groups—far exceeding those in most historical state-level conflicts—and highlights tactics like ambushes, raids, and mutilation that rival or exceed modern atrocities in brutality . Keeley's analysis critiques the underreporting of violence in ethnographic accounts of hunter-gatherers and horticulturalists, attributing it to anthropologists' aversion to portraying "primitive" societies negatively, which he links to a Rousseauian bias favoring views of civilization as the corrupter of innate human harmony. By comparing global datasets, he demonstrates that non-state warfare often lacked restraints like truces or mercy for combatants, leading to higher risks of annihilation for losing groups, and challenges the sequence that war emerged solely with agriculture or states, instead positing it as a near-universal feature of human social organization predating sedentary life. The work's significance lies in its empirical rebuttal to pacifist interpretations of prehistory, influencing subsequent scholarship on human violence, including Steven Pinker's The Better Angels of Our Nature, though it has faced pushback from researchers emphasizing variability in warfare intensity across contexts.

Overview

Publication Details and Author Background

War Before Civilization: The Myth of the Peaceful Savage was first published in hardcover by on February 22, 1996, with 978-0195091120. A paperback edition followed on December 18, 1997, under 978-0195119121. The book spans 272 pages and includes bibliographical references and an index. Lawrence H. Keeley (1948–2017) was an American anthropologist and professor emeritus at the University of Illinois at Chicago, where he taught until his retirement in 2014.

His work emphasized quantitative data from archaeological and ethnographic records to challenge prevailing assumptions about pre-state societies. Keeley died on October 11, 2017, at age 69.

Core Thesis and Structure of the Book

In War Before Civilization: The Myth of the Peaceful Savage, published in 1996, Lawrence H. Keeley advances the central thesis that organized violence and warfare were endemic to prehistoric and non-state societies, often exceeding in frequency, lethality, and ferocity the conflicts of modern civilized nations. He directly refutes the influential anthropological orthodoxy, rooted in Enlightenment-era romanticism and perpetuated by 20th-century scholars like those influenced by Margaret Mead's Samoan fieldwork, which portrayed hunter-gatherers and early horticulturalists as inherently pacific, with war emerging only as a of around 5,000 years ago. Keeley marshals empirical data to argue that this "pacified past" narrative stems from selective evidence interpretation, where ambiguous archaeological remains are deemed non-violent by default and ethnographic reports of tribal raids are dismissed as atypical or post-contact distortions. Instead, he posits that primitive warfare—characterized by ambushes, massacres, and trophy-taking—served adaptive functions like resource control and social cohesion, resulting in casualty rates (often 15-60% of adult male deaths from violence in studied groups) far surpassing the 1-2% typical in 20th-century industrialized wars. Keeley's analysis underscores causal realism in violence: war arises from human predispositions toward , amplified by small-scale societies' lack of centralized deterrence, rather than being a civilizational . He critiques institutional biases in , where interdisciplinary pressures favor narratives minimizing innate to align with ideals, leading to underreporting of fortifications, skeletal (e.g., wounds in 20-40% of prehistoric remains from sites like Ofnet, , circa 5000 BCE), and ethnographic parallels in groups like the , where 30% of adult deaths trace to feuding. This thesis challenges deterministic models positing or as war's sole triggers, instead emphasizing ubiquitous intergroup competition in stateless contexts. The book's structure proceeds logically from critique to evidence to synthesis. It opens with "The Pacified Past," dissecting the myth's origins in anthropology's aversion to ethnocentric judgments and its reliance on unrepresentative "peaceful" ethnographies. Subsequent chapters, such as those on evidence (e.g., fortified villages like , circa 8000 BCE, with skull cults indicating ritual violence) and hypotheses, systematically review archaeological data, rejecting claims of a "pre-warfare" era by highlighting overlooked indicators like mass burials at Talheim, (circa 5000 BCE), where 34 individuals show execution-style trauma. Ethnographic sections draw on over 40 non-state societies to quantify warfare's ubiquity, followed by comparative analyses revealing primitive conflicts' higher per capita destructiveness. The volume concludes with methodological reflections on evidence biases and philosophical inquiries into war's inevitability, advocating rigorous, data-driven reinterpretation over ideological priors.

Historical and Intellectual Context

Origins of the Noble Savage Myth

The concept of the , depicting pre-civilized humans as inherently virtuous, peaceful, and uncorrupted by societal institutions, emerged from ancient critiques of urban decadence rather than empirical observation of primitives. historian Publius Cornelius , in his ethnographic work composed around 98 AD, portrayed Germanic tribes as embodying simplicity, loyalty, martial valor, and sexual restraint—qualities he contrasted sharply with the perceived moral decay of imperial society. ' idealized depiction served a rhetorical purpose to shame his contemporaries, establishing an early template for viewing "barbarians" as morally superior foils to civilized excess. Renaissance humanism refined this archetype through direct encounters with New World peoples. In his 1580 essay "Of Cannibals," Michel de Montaigne drew on reports of Tupinambá practices in to argue that these "savages" adhered more closely to and reason than Europeans, whose sophisticated laws masked hypocrisy and cruelty; he famously contended that , while alien, paled against the of European judicial and warfare. Montaigne's inverted ethnocentric hierarchies, suggesting primitives retained a purer form of humanity unmarred by artificial customs. The specific phrase "" entered English usage in John Dryden's 1672 play The Conquest of Granada, where it evoked a freedom predating oppressive laws: "I am as free as nature first made man, / Ere the base laws of servitude began, / When wild in woods the ran." This literary flourish romanticized untamed existence amid growing European awareness of colonial subjects. By the , Jean-Jacques Rousseau's 1755 Discourse on the and Basis of Among Men amplified primitivist themes, hypothesizing a pre-social "natural man" driven by self-preservation and pity rather than vice, though Rousseau neither coined the term nor endorsed contemporary "savages" as paragons—his was an abstract construct critiquing 's corrupting effects. Anthropologist Ter Ellingson, in his 2001 analysis, demonstrates that the enduring attribution of the to Rousseau as a wholesale endorsement of constitutes a 19th-century scholarly fabrication, primarily by figures like , who weaponized it as a strawman to rationalize colonial hierarchies and dismiss egalitarian amid rising racial . This misconstruction persisted in academic discourse, embedding assumptions of pre-civilized harmony that overlooked ethnographic and archaeological evidence of pervasive tribal conflict.

Anthropological and Archaeological Biases Prior to Keeley

Prior to the 1996 publication of War Before Civilization, anthropological and archaeological scholarship largely dismissed or minimized the prevalence of organized violence in prehistoric societies, asserting that true warfare emerged only with the and the formation of agricultural or state-level polities around 10,000 years ago. This consensus portrayed hunter-gatherers as engaging in little more than individualistic homicides, ritual executions, or rare feuds, rather than collective, lethal conflicts akin to war. For instance, influential mid-20th-century works like Harry Holbert Turney-High's Primitive War (1949) established a conceptual "military horizon," demarcating non-state societies below it as incapable of "real" warfare due to lacking , tactics, or objectives, thereby reclassifying intergroup raids and ambushes as sub-war phenomena. Archaeological interpretations reinforced this view by systematically underinterpreting physical evidence of . Skeletal remains showing perimortem trauma—such as embedded projectile points, parry fractures, or decapitations—were frequently attributed to hunting mishaps, accidents, or isolated murders rather than interpersonal or intergroup aggression, even in cases of mass graves like the Crow Creek site in (circa A.D. 1325, but analogous to earlier denials). Fortifications, palisades, and weapon caches from pre-agricultural contexts were explained away as defensive against animals or symbolic structures, not human threats. Keeley noted that surveys of major textbooks from the era revealed 13 out of 14 explicitly claiming warfare's absence or insignificance before settled societies, reflecting a disciplinary aversion to recognizing as endemic to small-scale groups. These biases arose from methodological constraints, such as requiring "civilized" attributes like uniforms or declarations of war to qualify evidence as warfare, combined with ideological inclinations toward romanticizing non-state life as inherently pacific and egalitarian. Ethnographic data on contemporary hunter-gatherers, including high homicide rates in groups like the (up to 30% of adult male deaths from violence in some villages) or Australian Aboriginals, were selectively downplayed in favor of peaceful exemplars like the !Kung San, whose low observed violence was atypical and context-dependent. This selective emphasis, often unmoored from comprehensive cross-cultural analysis, aligned with post-World War II academic trends prioritizing anti-militaristic narratives, potentially amplified by institutional preferences in for views that critiqued Western civilization's role in fostering aggression over empirical scrutiny of universal human propensities.

Key Arguments and Evidence

Archaeological Evidence of Prehistoric Warfare

Archaeological evidence for includes skeletal remains exhibiting from weapons, mass graves indicative of group killings, fortified settlements suggesting defensive needs, and artifacts such as projectile points embedded in bones. These findings span from the to the , contradicting earlier scholarly tendencies to interpret such violence as rare or ritualistic rather than organized . Rates of lethal in some prehistoric populations reached 15-25% among adult males, exceeding those in many historical wars. One of the earliest datasets comes from (Site 117), a cemetery in dated to approximately 13,400-13,000 years ago, where over half of the 61 individuals show signs of interpersonal violence, including embedded lithic points from arrows or spears and perimortem fractures. Recent reanalysis of the skeletons reveals healed and unhealed injuries across multiple episodes, indicating sustained low-level conflict rather than a singular , with trauma concentrated on extremities and torsos consistent with or skirmish tactics. In , the in southwestern , dated to around 5000 BCE, contains the remains of 34 individuals—mostly women, children, and elderly males—with clustered cranial blunt-force trauma suggesting systematic executions, possibly by a raiding party targeting non-combatants after killing adult males elsewhere. Isotopic and genetic analyses confirm the victims as local kin groups, ruling out intra-community violence and supporting intergroup aggression. Similar massacres occur at Schöneck-Kilianstädten (, ~5000 BCE), where 26 skeletons display perimortem injuries from clubs and adzes, and Schletz (), a fortified Linearbandkeramik site with evidence of burned structures and defensive ditches breached during assault. The Crow Creek site in , , dated to circa 1325 but representing late prehistoric Plains village societies, yielded a with over 450 commingled skeletons showing , , and defensive wounds, with 90% of adults exhibiting trauma consistent with a coordinated village and slaughter. Bioarchaeological examination indicates attackers spared few, depositing mutilated bodies in a fortification ditch, reflecting escalated inter-village warfare amid resource competition. Mesolithic evidence from Ofnet Cave in , (~7500 BCE), includes two clusters of 33 skulls—predominantly female and subadult—arranged in "nests" with perimortem cutmarks and fractures indicative of and trophy-taking post-mortem, patterns aligning with aftermaths rather than ritual sacrifice. Across , over 100 fortified enclosures with palisades, ditches, and gates appear from 5500-4000 BCE, such as those in the valley, where burn layers and weapon caches suggest repeated sieges and counterattacks driven by territorial disputes. These assemblages, when quantified, show accounting for 10-20% of mortality in many pre-state societies, with male-biased patterns implying organized raiding for or resources, challenging interpretations that downplayed warfare due to incomplete preservation or ideological preferences for peaceful models.

Ethnographic Data on Tribal

Ethnographic studies of non-state societies, including hunter-gatherers and tribal groups, document elevated rates of lethal , often manifesting as chronic feuding, raids, and warfare that account for substantial portions of mortality. In the of the , approximately 30% of adult male deaths result from , with 44% of males aged 25 or older having participated in at least one killing. Nearly 70% of adults over 40 have lost a close genetic relative to such , underscoring the intergenerational cycle of killings and raids. Among the Waorani of the Ecuadorian Amazon, violence has caused about 60% of adult deaths across five generations, driven by persistent feuds and retaliatory killings. The Grand Valley Dani of exhibit homicide rates equivalent to 1,000 violent deaths per 100,000 people annually, reflecting frequent pig-raiding wars that escalate into lethal confrontations. Similarly, the Kato (Cahto) of 1840s recorded 1,450 violent deaths per 100,000 per year, indicative of intergroup conflicts over resources and territory. In lowland South American tribal groups, compilations from 11 anthropological studies show violence accounting for roughly 30% of adult deaths, with males comprising about 70% of victims, often from ambushes and revenge expeditions. The Gebusi of report 35.2% of male and 29.3% of female deaths due to , including accusations leading to executions and . These patterns persist in unpacified or minimally contacted groups, where ethnographic fieldwork captures endemic raiding and as normative responses to disputes over women, resources, or honor, contrasting sharply with the lower levels enforced by monopolies on . While some researchers debate exact figures due to underreporting or definitional variances, the aggregate data affirm as a pervasive feature of tribal .

Comparative Lethality and Frequency of Pre-Civilized vs. Civilized War

Keeley argues that the lethality of warfare, measured as the proportion of total deaths attributable to combat, was substantially higher in non-state societies than in civilized ones. Ethnographic data from tribal groups indicate that warfare caused an average of approximately 15% of all deaths, with rates varying widely but often exceeding 30% for adult males in particularly violent societies such as the and Waorani. In contrast, even during the most destructive twentieth-century conflicts, such as , war-related deaths constituted less than 1% of total deaths across combatant populations when normalized over lifetimes or generations, with annual combat mortality rates around 0.15%. Archaeological evidence from prehistoric sites reinforces this disparity, with violent death rates estimated at 10-20% or higher in many cases, compared to under 5% in ancient state societies like those in nineteenth-century . Annual death rates from warfare in non-state societies were typically two to fifty times higher than those in state-level warfare of the twentieth century, reflecting tactics like ambushes and raids that inflicted near-total casualties on small groups rather than the partial losses in pitched battles of larger armies. For instance, in the Dugum Dani of , warfare accounted for about 35% of male s, while ethnographic surveys of groups like the Mae Enga show similar patterns. Keeley attributes this elevated lethality to the absence of medical infrastructure, the targeting of non-combatants, and the lack of truces or quarter in tribal conflicts, contrasting with civilized warfare's logistical constraints and occasional restraints. Regarding frequency, Keeley documents that non-state societies experienced warfare far more routinely than assumed, with ethnographic samples revealing 65% in continuous , 87% fighting more than once per year, and only 13% enjoying a decade or more of . Approximately 86% of surveyed non-state groups were either raiding or defending against raids at any given time, underscoring endemic driven by and cycles. In state societies, by comparison, full-scale wars occur less pervasively, often separated by years or decades of relative , though total casualties may accumulate higher in absolute terms due to scale; Keeley emphasizes that exposure remains lower, as state monopolies on suppress internal raiding. This pattern holds across 90-95% of known societies, where peaceful exceptions are typically isolated or transient refugees rather than normative.

Methodological Foundations

Keeley's Data Selection and Analytical Framework

Keeley selected archaeological data by prioritizing physical indicators of collective violence, such as fortifications (e.g., ditches and palisades surrounding ), skeletal remains exhibiting from weapons (e.g., embedded arrowheads, axe wounds, or injuries), mass burials suggestive of , and evidence of settlement destruction like burn layers. He applied strict criteria to distinguish warfare from individual or accident, requiring contextual clustering of injuries (e.g., multiple skeletons with perimortem in one site) and association with defensive structures, drawing from sites spanning the to periods, such as Talheim, (where 34 individuals showed axe-related wounds indicating a group execution around 5000 BCE), Gebel Sahaba, (over 40% of burials with projectile injuries circa 13,000 BCE), and Crow Creek, (a site with nearly 500 scalped and dismembered bodies from the 14th century CE). This selection countered prior archaeological tendencies to underreport or reclassify violence evidence as non-warlike, emphasizing verifiable osteological and structural data over interpretive assumptions. For ethnographic data, Keeley drew from cross-cultural compilations like the by , focusing on non-state societies (bands, tribes, and chiefdoms) minimally influenced by external states to approximate pre-civilizational conditions. He selected cases with detailed records of participation, casualties, and , excluding pacified or colonial-altered groups, and analyzed over 90 societies where warfare documentation was robust, such as the of (frequent raids causing 5% casualties in short periods) and the Dugum Dani of (endemic feuding with high male mortality). Surveys indicated that 90% of such societies engaged in , with peaceful exceptions (e.g., Semai of ) being rare and often geographically isolated. This approach privileged quantitative ethnographic accounts from anthropologists like Chagnon and Heider, while acknowledging variability but rejecting selective sampling that overstated . Keeley's analytical quantified warfare's impact through metrics of , , and scale, enabling direct comparisons between non-state and state societies. was assessed via the percentage of attributable to (primarily warfare for males) or annualized rates, revealing non-state societies often exceeding 15-60% lifetime violent mortality for adult males—far higher than 1-2% in 20th-century states. For instance, ethnographic showed annual warfare rates of 0.5% or more in tribal groups (e.g., 1.0% among the Dani, 1.45% among the Karo), compounding to 25% or higher over a 50-year lifespan, versus 0.07% in historical . was measured by time spent in conflict, with non-state groups at 65-87% of years versus intermittent state engagements (e.g., legions active once every 6-20 years). rates highlighted near-total societal involvement in warfare, contrasting partial levies in states. To address interpretive biases, Keeley incorporated meta-analysis of prior scholarship, critiquing post-World War II anthropology and archaeology for "pacifying the past" by dismissing violence evidence as atypical or ritualistic, often due to ideological preferences for Rousseauian narratives over empirical patterns. He cross-validated archaeological and ethnographic findings against historical analogs, arguing that under-detection of low-visibility raids (common in non-state warfare) systematically underestimated prehistoric violence, and advocated conservative estimates to avoid overstatement. This framework prioritized causal inference from material traces and longitudinal data, rejecting unsubstantiated assumptions of evolutionary pacifism in favor of observed regularities in human conflict.

Challenges in Interpreting Prehistoric Remains

Interpreting prehistoric remains for of warfare is complicated by taphonomic processes, which differentially preserve skeletal and often result in incomplete assemblages that underestimate prevalence. For instance, perimortem injuries may degrade or be obscured by post-depositional factors such as acidity, animal scavenging, or , particularly in open-air sites where organic remains rarely survive beyond 10,000-20,000 years. This scarcity limits reliable documentation to relatively recent periods and specific regions with favorable conditions, such as sites or arid environments. Distinguishing warfare-related trauma from other causes poses further interpretive hurdles, as skeletal lesions like fractures or embedded projectiles can stem from accidents, mishaps, practices, or interpersonal disputes rather than organized . Healed antemortem injuries, for example, are frequently attributed to non-violent pathologies or isolated without contextual indicators of collective violence, such as clustered perimortem traumas across multiple individuals of diverse ages and sexes. Bioarchaeological analyses require rigorous criteria, including the differentiation of sharp-force from blunt-force and exclusion of taphonomic mimics, yet subjective judgments persist in assigning intent. Archaeological practice has historically exhibited biases that minimize recognition of prehistoric violence, with postwar scholars often reinterpreting mass graves or fortified settlements as ceremonial or defensive against natural hazards rather than human threats. This "pacification of the past" reflects an ideological preference for viewing pre-civilized societies as inherently peaceful, influenced by ethnographic analogies to rare non-warring groups, leading to underreporting of unambiguous evidence like scalping or trophy-taking until challenged by systematic re-evaluations. Sampling and excavation biases exacerbate these issues, as most prehistoric sites remain unexcavated, and violent deaths may occur in peripheral or unpreserved locations away from s, yielding rather than absence of evidence. Indirect proxies, such as distributions or patterns, provide ambiguous signals without corroborating skeletal , complicating attributions of lethality or frequency to warfare over sporadic feuds. Despite advances in forensic techniques like scanning for hidden fractures, these methodological constraints demand multidisciplinary integration to avoid overreliance on incomplete proxies.

Criticisms and Counterarguments

Methodological Critiques from Opponents

Critics of Keeley's methodology have argued that his selection of archaeological sites introduces , as excavations revealing violence are more likely to be published and emphasized, while peaceful sites may go underreported due to taphonomic factors or interpretive preferences. Samuel Bowles, in analyzing warfare mortality among hunter-gatherers, noted that such bias in archaeological studies, including those cited by Keeley, could exaggerate the prevalence of violent deaths, as non-violent remains are less distinctive and thus underrepresented in the record. This concern echoes broader methodological challenges in prehistoric research, where the absence of in many skeletons does not conclusively prove but may reflect preservation issues or under-identification of interpersonal violence. Brian Ferguson, in his review published in American Anthropologist, contended that Keeley overstates the commonality of by conflating sporadic evidence with universality, potentially substituting one interpretive for another without adequately addressing variability across regions and periods. Ferguson specifically critiqued Keeley's reliance on ethnographic analogies from contemporary tribal societies to reconstruct behavior, arguing that these groups often reflect post-contact dynamics influenced by states or , rather than unadulterated conditions, thus invalidating direct projections backward in time. He emphasized that motivations and scales of violence in documented cannot reliably model earlier epochs without accounting for ecological and technological differences. Keith Otterbein further challenged Keeley's framework by disputing the assumption of warfare's continuity from humanity's origins, proposing instead that methodical analysis of weaponry evolution—such as the advent of thrown spears around 400,000 years ago—indicates organized intergroup conflict emerged later and in specific lineages, rather than pervasively. Otterbein's cross-cultural review highlighted flaws in Keeley's aggregation of diverse ethnographic and archaeological data into uniform lethality metrics, which overlook phylogenetic and environmental contingencies, leading to an overgeneralized narrative of inherent bellicosity. These critiques, while acknowledging Keeley's compilation of overlooked evidence, underscore the risks of confirmation bias in favoring violence-centric interpretations amid incomplete prehistoric datasets.

Debates on the Universality of Prehistoric Violence

The central debate surrounding the universality of prehistoric violence questions whether organized warfare was an endemic feature of human societies prior to or if it was largely absent or episodic in many groups, emerging only under specific ecological or social pressures. Lawrence Keeley maintained that archaeological and ethnographic data demonstrate warfare's prevalence across diverse prehistoric contexts, including mobile forager bands, with lethality rates often exceeding those in historical state-level conflicts; he attributed scholarly underappreciation to interpretive biases favoring peaceful baselines in the absence of overt evidence. Critics, including R. Brian Ferguson, contend that systematic warfare intensified with , resource competition, and during the transition, remaining rare or nonexistent among egalitarian, nomadic s where mobility and low stakes discouraged escalation; Ferguson highlights scant unambiguous pre-Mesolithic evidence for intergroup conflict, suggesting war's origins lie in anthropogenic environmental changes rather than innate tendencies. Supporting non-universality, Douglas Fry argues that ethnographic accounts of "simple" foragers—such as certain Australian Aboriginal bands—reveal violence primarily as individualized homicide or feuds rather than coordinated communal warfare, with peaceful conflict resolution via avoidance or predominant in daily life; he estimates deadly intergroup episodes as exceptional, not chronic, in unsegmented societies lacking territorial defenses. Skeletal analyses from the Jomon period in prehistoric (ca. 13,000–800 BCE), a culture with semi-sedentary villages, indicate violence-related mortality at approximately 1.82% overall, with no concentrated "hot spots" or fortifications, implying warfare was neither pervasive nor evolutionarily entrenched in such contexts. These cases suggest variability, where sparse populations and abundant resources could suppress organized violence, challenging blanket assertions of ubiquity. Keeley and proponents counter that apparent absences reflect taphonomic biases—perishable evidence like wooden weapons or unfortified camps decays, while positive indicators like the massacre (ca. 10,000 BP) in nomadic Kenyan foragers demonstrate deliberate intergroup raids with bound victims and , extending warfare's record deep into the . Ethnographic extrapolations risk survivor bias, as highly violent groups may self-extinguish, leaving records dominated by less aggressive ones, yet cross-cultural surveys show warfare participation in over 80% of studied non-state societies, with male mortality from conflict averaging 10–60% in some forager cases like the . Recent syntheses affirm 's role in shaping dynamics, with genomic and osteological data revealing recurrent patterns of internecine conflict, though debates persist on whether "universality" requires presence in every society or merely predominance across human evolutionary history. This contention underscores interpretive challenges, where ideological preferences for pre-state harmony—prevalent in mid-20th-century amid anti-imperial sentiments—may have minimized indicators, as Keeley critiqued, versus empirical aggregation favoring its normalcy.

Reception and Academic Impact

Initial Scholarly Reviews

Upon its publication in 1996, Lawrence H. Keeley's War Before Civilization: The Myth of the Peaceful Savage received scholarly attention primarily in and journals, where reviewers acknowledged its role in challenging the prevailing of low prehistoric . Keith F. Otterbein, in a 1997 review essay published in Critical Review, endorsed Keeley's central argument that prehistoric and primitive societies exhibited warfare more pervasive and lethal than typically portrayed by scholars influenced by Rousseauian ideals, citing ethnographic and archaeological data showing chronic raiding and high casualty rates among non-state groups. Otterbein highlighted Keeley's quantitative comparisons, such as tribal warfare death rates exceeding those in modern states, as compelling evidence against the "" myth, though he noted the need for further cross-cultural validation. A capsule review in (November 1996) similarly praised the book for documenting "cruel, chronic, and systematic warfare" in most societies, arguing it refuted claims of war's invention by civilization through examples like massacres at sites such as Crow Creek (, circa A.D. 1325) with over 500 scalped victims. However, early critiques emerged regarding Keeley's data selection; for instance, some reviewers in anthropological outlets questioned the representativeness of his ethnographic samples, which emphasized mobile s over sedentary foragers, potentially inflating violence estimates. R. Brian Ferguson, in subsequent commentary building on initial reactions, conceded Keeley's evidence of frequent violence but contended it overstated warfare's universality in contexts, attributing some bias to selective emphasis on lethal outcomes over peaceful intervals. Overall, initial academic responses positioned the as a catalyst for reevaluating prehistoric , with on elevated non-state —e.g., Keeley's cited 15-60% male mortality from warfare in some tribes versus 1% in 20th-century —but debates persisted on interpretive frameworks, influencing later studies in . These reviews underscored a shift away from ideologically driven minimization of , prioritizing empirical skeletal and ethnographic records over theoretical . Keeley's War Before Civilization (1996) prompted a in , particularly , by critiquing the Rousseauian idealization of non-state societies as inherently peaceful, which had dominated interpretations of ethnographic on tribal . This encouraged anthropologists to reassess small-scale societies not through selective, idyllic ethnographies but via comparative analysis incorporating archaeological and historical records, revealing higher rates of intergroup conflict than previously acknowledged. In archaeology, the book spurred a resurgence of research on starting in the late , transforming violence from a marginalized topic—often dismissed as atypical or post-contact—to a central in interpreting settlement patterns, fortifications, and . Post-1996 studies expanded on Keeley's framework by systematically documenting skeletal evidence of trauma, such as parry fractures and projectile wounds, across sites like (circa 13,000 BCE) and Crow Creek (circa 1325 ), where up to 60% of remains showed violent injuries, thereby validating and extending his arguments on warfare's prevalence. The work's influence extended to and , fostering interdisciplinary approaches that integrate forensic analysis of remains with genetic and isotopic data to distinguish interpersonal from warfare, while emphasizing variability in conflict intensity across regions and periods rather than universal . Keeley's emphasis on empirical metrics—such as 15-60% war-related mortality in ethnographic non-state groups versus under 1% in 20th-century states—influenced evolutionary models of human aggression, as seen in citations within discussions of 's adaptive role. Related fields, including , adopted Keeley's data to counter narratives minimizing innate human propensity for organized ; for instance, referenced the book's findings on prehistoric casualty rates exceeding those of modern conventional wars to support arguments for a long-term decline in since the transition to states. Overall, by 2011—15 years post-—archaeological interest in had notably intensified, with Keeley noting a shift toward viewing as both cause and in social evolution, though debates persist on interpretive biases favoring peaceful reconstructions due to institutional preferences for anti-militaristic interpretations.

Post-Publication Developments and Legacy

Confirmatory Evidence from Subsequent Research

Subsequent archaeological investigations have bolstered Keeley's contention that organized violence, including warfare, was prevalent in prehistoric societies, with numerous post-1996 studies documenting skeletal trauma, mass graves, and defensive fortifications indicative of intergroup conflict. For instance, analyses of Linearbandkeramik (LBK) culture sites in , dating to the early (ca. 5500–5000 BCE), have revealed multiple involving blunt force trauma, arrow wounds, and disarticulated remains suggestive of or , as seen at Schöneck-Kilianstädten where at least 26 individuals were killed in a single event. Similar evidence emerges from Els Trocs in the Spanish Pyrenees (ca. 5300 BCE), where isotopic and trauma analysis of 13 individuals indicates a targeted of a farming community, with perimortem injuries from adzes and arrows. In contexts, a 2016 bioarchaeological study of over 6,000 burials from (spanning 1,530–230 cal ) found sharp force consistent with projectile weapons in 7.4% of cases, rising to 10.7% among males, with correlating strongly to resource scarcity measured by net primary productivity rather than sociopolitical . Reexaminations of older sites, such as in (terminal Pleistocene), using modern microscopy and CT scans, confirmed high interpersonal rates among hunter-gatherers, with embedded arrowheads and parry fractures underscoring ruthless conflict patterns. Broader syntheses, including Steven LeBlanc's 2003 analysis of global archaeological records, affirm warfare as a persistent response to ecological pressures and population growth, documenting fortified settlements and massacre sites across Paleolithic, Mesolithic, and Neolithic periods worldwide, thus extending Keeley's critique of the peaceful prehistoric narrative. In late Neolithic Poland (ca. 3000 BCE), genomic analysis of a mass grave containing 15 related individuals revealed blunt and sharp force trauma from a coordinated attack, exemplifying "total war" dynamics Keeley described. These findings, coupled with rising frequencies of healed and lethal skeletal injuries in transitioning to sedentary lifestyles, indicate that violence levels often exceeded those in early state societies, challenging underreporting biases in prior interpretations.

Broader Implications for Human Nature and Societal Evolution

Keeley's empirical reconstruction of prehistoric warfare reveals that non-state societies experienced violent death rates far exceeding those in civilized contexts, with ethnographic data indicating annual war-related mortality of approximately 0.5% of the population—equivalent to 500 deaths per 100,000 annually—compared to 0.01% or less in twentieth-century states. This disparity implies that humans possess an evolved capacity for organized, lethal intergroup conflict, independent of complex institutions, as evidenced by consistent patterns of raiding, ambushes, and massacres across diverse foraging and tribal groups. Such findings counter Rousseauian ideals of innate human benevolence corrupted solely by civilization, suggesting instead that aggression manifests robustly in the absence of centralized authority, shaped by kin-based loyalties and resource competition. From an evolutionary standpoint, the ubiquity of prehistoric violence points to selection pressures favoring traits like in-group paired with out-group , as chronic warfare in small-scale polities would have rewarded groups capable of coordinated and offense. Archaeological cases, including fortified settlements from the period onward—such as those in dating to around 8000 BCE—demonstrate early escalations in , underscoring how intergroup strife drove innovations in and . This dynamic aligns with models of cultural , where polities expanding beyond tribal scales outcompeted rivals through superior military mobilization, gradually supplanting endemic feuding with monopolized coercion. Societally, Keeley's work highlights civilization's potential role in constraining violence's scope, as correlates with per capita declines in and warfare fatalities, from 15-25% of adult male deaths in some non-state societies to under 5% in historical empires. However, this pacification exacts trade-offs, including the amplification of violence's total scale through industrialized means, challenging utopian visions of reverting to "primitive" harmony and reinforcing a causal view that unchecked human tendencies toward factional conflict necessitate hierarchical structures for stability. Academic reluctance to acknowledge these patterns, often rooted in ideological preferences for portraying pre-civilized life as idyllic, has historically skewed interpretations toward undercounting skeletal and overemphasizing peaceful anomalies.
