War and society is a subfield of military history that examines armed conflict not as a self-contained technical activity but as a social phenomenon. Where operational military history asks how battles were fought and won, war and society asks how societies produce, sustain, experience, and are transformed by war. Its central questions concern the relationships among military institutions, political power, economic structures, culture, and everyday life: Who fights, and why? How do societies mobilize resources for war, and what are the consequences? How do wars reshape social hierarchies, gender roles, citizenship, and collective memory? The subfield treats war as both a product of social conditions and a force that remakes them.
The study of war and society grew out of a dissatisfaction with the narrowness of traditional military history, which for much of the nineteenth and early twentieth centuries focused on campaigns, generalship, and the technical details of weaponry. That older tradition, often written by and for military professionals, treated war largely as a matter of strategy and command. A broader approach began to take shape in the mid-twentieth century, influenced by social history, sociology, and political science. Scholars started asking not only how armies fought but how they were recruited, fed, financed, and governed, and what war meant for the civilians who endured it.
The field crystallized in the 1960s and 1970s, particularly in the work of historians who insisted that military institutions could only be understood in their social context. A key early influence was the German historian Hans Delbrück, who in the early twentieth century had argued that military organization and strategy were inseparable from political and economic structures. But the modern subfield drew more directly on the postwar expansion of social history, with its attention to ordinary people, class relations, and long-term structural change. The Vietnam War also shaped the field's development, prompting scholars in the United States and elsewhere to ask harder questions about how democracies wage war, how societies resist military service, and how war affects domestic politics.
The defining move of the subfield is to treat war as a social institution rather than an external event that happens to societies. This means studying the preparations for war as much as the fighting itself: conscription systems, military training, defense industries, taxation, and propaganda. It also means studying the aftermath of war, including demobilization, veteran welfare, commemoration, and the long-term health and demographic effects on populations.
A central theme is the relationship between war and state formation. Many scholars argue that the modern state, with its capacity to tax, administer, and coerce, developed in large part through the demands of war. The need to raise armies and pay for them forced rulers to build bureaucracies, negotiate with elites, and ultimately grant political rights in exchange for revenue. This argument, associated strongly with the historical sociologist Charles Tilly, holds that war made the state and the state made war. The claim is not that war is the only driver of state development, but that the fiscal and administrative pressures of warfare were a central mechanism in European state-building from the early modern period onward. The argument has been extended and tested in other regions, with scholars asking whether similar dynamics operated in East Asia, the Middle East, or Africa, and whether the European pattern is exceptional rather than universal.
Another major theme is the social composition of armed forces. Who serves in a society's military reflects and reinforces its social hierarchies. Conscription systems, for example, have often exempted the wealthy, who could purchase substitutes or claim educational deferments, while the poor and rural populations supplied the bulk of soldiers. Armies have also been sites where racial and ethnic hierarchies are enforced or contested, from the segregated units of the U.S. military before the Korean War to the colonial troops recruited by European empires. Gender is equally central: military service has historically been tied to masculine citizenship, with women excluded from combat roles even as they took on new responsibilities in wartime economies. The study of these patterns reveals how war both depends on and reproduces social inequality.
Beginning in the 1980s and 1990s, the subfield absorbed the broader "cultural turn" in the humanities. Scholars increasingly asked not just how societies organized for war but how they made sense of it. This line of research examines war memorials, literature, film, photography, and public rituals to understand how societies represent conflict and how those representations shape future attitudes toward violence. A central concept is "war culture," the set of beliefs, images, and narratives through which a society understands armed conflict. These cultural frameworks matter because they influence political decisions: a society that remembers a war as a noble sacrifice may be more willing to fight again, while one that remembers it as a catastrophe may be more cautious.
The cultural approach also investigates the experience of war from the inside, using letters, diaries, oral histories, and material objects to reconstruct what combat felt like for ordinary soldiers. This "history from below" has transformed understanding of the First World War, for example, moving beyond the familiar story of generals and offensives to examine the daily lives of soldiers in the trenches, their relationships with each other, their fears and coping mechanisms, and their attitudes toward the enemy. A related concept is the "face of battle," a phrase associated with the historian John Keegan, who argued that military history had neglected the actual experience of combat in favor of abstract operational analysis. The study of combat experience has since become a rich area in its own right, drawing on psychology and anthropology as well as history.
A significant portion of the subfield's attention has focused on the phenomenon of total war, particularly the world wars of the twentieth century. Total war is characterized by the mobilization of entire societies, the blurring of boundaries between combatants and civilians, and the targeting of the enemy's economic and moral capacity to fight. The concept is contested: some scholars argue that it describes a genuinely new form of warfare that emerged in the nineteenth and twentieth centuries, while others see it as an ideal type that no actual war fully achieved. Nevertheless, it provides a useful framework for studying how industrial societies organized for mass conflict.
The world wars are central to war and society because they involved unprecedented mobilization of civilian populations. Women entered factories in large numbers, governments rationed food and controlled information, and entire economies were reoriented toward military production. The consequences were profound and lasting: the expansion of state welfare programs, the acceleration of social change, the redrawing of national boundaries, and the creation of new forms of citizenship. The Holocaust, which occurred within the context of the Second World War, raises particularly difficult questions about the relationship between war and genocide, and scholars continue to debate whether the mass murder of European Jews should be understood as an outcome of the war itself or as a separate project that the war enabled.
The atomic bombings of Hiroshima and Nagasaki introduced a new dimension to the study of war and society. Nuclear weapons raised the stakes of conflict to the point where the survival of entire societies was at risk, and the Cold War that followed created a permanent state of military preparedness in the United States and the Soviet Union. The study of the Cold War as a social phenomenon, including the nuclear family, suburban civil defense, and the military-industrial complex, has become an important area of research. Scholars examine how the threat of annihilation shaped everyday life, from school drills to popular culture, and how the permanent mobilization of the Cold War differed from the temporary mobilizations of earlier conflicts.
The subfield has become increasingly comparative and global. Early work in war and society focused heavily on Europe and North America, reflecting the institutional location of most practitioners. But scholars have since turned to the wars of decolonization, the Cold War's proxy conflicts in Asia, Africa, and Latin America, and the civil wars that have been more common than interstate wars since 1945. This expansion has raised questions about whether concepts developed from the European experience, such as total war or the military revolution, travel well to other contexts.
The study of civil war, in particular, has become a major area of research. Civil wars differ from interstate wars in important ways: the boundaries between combatants and civilians are often more fluid, the violence is frequently directed at noncombatants, and the conflict is intertwined with questions of political legitimacy and identity. Scholars have examined how civil wars reshape social relations, how they are remembered and commemorated, and how they end. The field has also engaged with the growing literature on genocide and mass violence, asking how societies become capable of extreme violence against their own populations.
Another important development is the attention to non-Western military traditions. The assumption that modern warfare originated in Europe and spread elsewhere has been challenged by scholars who point to the sophisticated military organizations of early modern Asia, Africa, and the Americas. The "military revolution" thesis, which holds that a series of innovations in early modern Europe transformed the scale and nature of warfare, has been criticized for ignoring parallel developments elsewhere. This debate matters for war and society because it affects how scholars understand the relationship between military organization and social development in different parts of the world.
The subfield today is characterized by methodological pluralism. Some practitioners work primarily with archival documents, reconstructing the administrative and political history of military institutions. Others use quantitative methods, analyzing demographic data, economic statistics, or patterns of violence. Still others draw on cultural theory, oral history, or material culture. This diversity is a source of strength, but it also creates tensions. Scholars who emphasize structural explanations, such as the fiscal demands of war, sometimes disagree with those who emphasize cultural factors, such as the narratives through which societies understand conflict. The relationship between these approaches is not one of succession but of ongoing conversation, with many scholars combining them.
A significant current debate concerns the relationship between war and gender. The traditional association of military service with masculinity has been challenged by research on women's roles in war, both as combatants and as supporters. Women have served in armed forces throughout history, though often in disguised or auxiliary roles, and they have been central to wartime economies and resistance movements. The integration of women into contemporary militaries has prompted historians to ask how military institutions construct gender and how changes in military organization reflect or drive changes in gender relations. This research has complicated the simple equation of soldiering with masculinity, showing that the relationship is historically variable.
Another area of active research is the memory of war. Scholars examine how societies remember and forget their wars, how commemorative practices change over time, and how competing memories of the same conflict can divide societies. The memory of war is not a passive reflection of what happened but an active process of construction, shaped by political interests, cultural conventions, and the experiences of different groups. The study of memory has become particularly important for understanding post-conflict societies, where the past remains politically charged.
The subfield also engages with contemporary policy questions. Scholars of war and society have contributed to debates about the all-volunteer military, the use of private military contractors, the treatment of veterans, and the ethics of drone warfare. The question of how societies bear the costs of war, and who bears them, remains as relevant as ever. The subfield's insistence that war cannot be understood apart from its social context gives it a critical perspective on contemporary military affairs, even as its practitioners disagree about the policy implications of their research.
War and society is thus not a single method or doctrine but a broad orientation toward the study of armed conflict. Its practitioners share a conviction that war is too important to be left to military professionals alone, and that the social dimensions of conflict are essential to understanding both its causes and its consequences. The field's enduring contribution has been to show that war is not an aberration from normal social life but a continuation of it by other means, shaped by the same structures of power, inequality, and culture that organize society in peacetime.
