For as long as historians have studied war, they have wrestled with a deceptively simple question: why are some campaigns won and others lost? The answer, for much of the nineteenth and early twentieth centuries, seemed to lie in the study of command decisions, troop movements, logistics, and battlefield tactics. This approach, known as Operational Military History, dominated the field for over a century. Yet by the 1960s, a growing number of scholars began to argue that the operational lens was too narrow—that wars could not be understood without examining the societies, economies, and ideologies that shaped them. The result was a series of challenges that transformed operational history from a single, confident narrative into a pluralistic field of competing frameworks, each offering a different answer to the same enduring question.
Operational Military History emerged in the nineteenth century as the dominant framework for studying war. Its practitioners focused on the mechanics of campaigns: the movement of armies, the decisions of commanders, the logistics of supply, and the outcomes of battles. The framework was shaped by the professionalization of military staffs and the rise of national war academies, where officers studied past campaigns to extract lessons for future wars. Works such as Antoine-Henri Jomini's Summary of the Art of War and Carl von Clausewitz's On War provided theoretical foundations, though Clausewitz's broader reflections on war's political nature were often set aside in favor of operational prescriptions.
Operational Military History treated war as a rational, manageable activity. Its practitioners assumed that the key to victory lay in superior planning, leadership, and execution. The framework produced detailed campaign narratives and staff rides that remain valuable for understanding the conduct of war. Yet by the mid-twentieth century, its limitations had become apparent. Operational history said little about why societies went to war, how economies sustained conflict, or how ordinary soldiers and civilians experienced violence. These gaps created space for new approaches.
The 1960s brought two simultaneous but distinct challenges to the operational consensus. Marxist Military History, drawing on the theoretical legacy of Karl Marx and Friedrich Engels, argued that wars were ultimately products of class conflict and economic structures. For Marxists, the operational details of a campaign were secondary to the material conditions that produced the war in the first place. A battle was not just a clash of armies but a reflection of deeper contradictions within a society—between capital and labor, between imperial powers and colonized peoples, between feudal and capitalist modes of production. Marxist historians such as John Ellis and others examined how class interests shaped military strategy, how conscription reflected social hierarchies, and how war accelerated or disrupted economic transformations.
At roughly the same time, the War and Society School emerged as a broader, less doctrinaire alternative. Rather than reducing war to class struggle, War and Society historians asked how war interacted with every dimension of social life: demography, public health, gender roles, technology, and state formation. The school drew on the methods of social history and the Annales tradition, emphasizing long-term structures over short-term events. Where Marxist Military History saw class as the primary driver, War and Society treated class as one factor among many. The two frameworks coexisted in productive tension. Both rejected the operational assumption that war could be studied in isolation from society, but they disagreed on which social forces mattered most. The War and Society School's broader scope eventually made it the more influential of the two, especially as military history departments in the United States and Britain began to incorporate social-historical methods.
By the 1980s, a new set of questions began to reshape the field. Cultural Military History shifted attention from the material and social conditions of war to the beliefs, identities, and representations that gave war meaning. Where War and Society historians studied the economic impact of conscription, cultural historians studied how nations imagined their soldiers. Where Marxists analyzed class interests, cultural historians analyzed gender ideologies, national myths, and the rituals of military life.
Cultural Military History did not reject the insights of the War and Society School or Marxist Military History, but it narrowed their explanatory claims. It argued that material conditions and social structures could not fully account for why people fought, how they experienced combat, or how they remembered war. Instead, cultural historians insisted that war was always mediated by language, symbols, and narratives. The framework drew on the broader cultural turn in the humanities, incorporating methods from anthropology, literary theory, and art history. Works such as John Keegan's The Face of Battle (1976) anticipated this shift by focusing on the subjective experience of soldiers, but the full cultural turn came later, with studies of war memorials, propaganda, and the construction of martial masculinity.
Cultural Military History coexists with the War and Society School rather than replacing it. Many historians now treat the two frameworks as complementary: War and Society provides the structural context, while Cultural Military History explores the meanings that actors attached to that context. The relationship with Marxist Military History is more strained, since cultural approaches often reject the primacy of economic determinism.
The 1990s brought a cluster of new frameworks that further pluralized the field. Deconstructivist Military History, drawing on poststructuralist philosophy, questioned the very categories that operational and social historians had taken for granted. Where earlier frameworks assumed that terms like "battle," "soldier," "victory," and "war" had stable meanings, deconstructivists argued that these categories were constructed through language and power. A deconstructivist analysis might examine how military archives themselves shape what can be known about a campaign, or how the distinction between "combatant" and "civilian" has shifted over time. This framework did not produce a large body of operational studies, but it influenced the field by making historians more self-conscious about their sources and categories. Its skepticism about grand narratives challenged both Marxist teleologies and operational certainties.
Global Military History emerged from a different set of pressures: the recognition that most military history had been Eurocentric, focused on the wars of Western states. Global historians argued that the operational and social frameworks developed for European wars could not simply be exported to other contexts. Instead, they insisted on studying war as a global phenomenon shaped by cross-cultural encounters, imperial expansion, and non-Western military traditions. Global Military History shares with the War and Society School a commitment to contextual explanation, but it widens the context to include planetary-scale processes such as colonialism, trade networks, and environmental change. The two frameworks overlap in their attention to social structures, but Global Military History is more attentive to power asymmetries between regions and to the agency of non-European actors.
Memory-Oriented Military History, also emerging in the 1990s, focused on how wars are remembered, commemorated, and contested after they end. This framework built directly on Cultural Military History's interest in representations, but it shifted the temporal focus from the wartime moment to the postwar afterlife. Memory historians study war memorials, veterans' testimonies, film, and public rituals to understand how societies make sense of violence over time. The framework has been especially influential for understanding the world wars, where national memory has been a site of political struggle. Memory-Oriented Military History does not compete with operational history so much as extend it: operational historians ask what happened in a battle; memory historians ask how that battle came to mean what it does today.
Today, operational history is a field of living frameworks rather than a single orthodoxy. The War and Society School, Cultural Military History, and Global Military History are the most active and influential approaches, each with its own journals, conferences, and canonical works. Marxist Military History continues as a smaller but persistent tradition, especially among historians of labor and imperialism. Deconstructivist Military History remains a critical voice, more often cited for its methodological caution than for its empirical findings. Memory-Oriented Military History has become a thriving subfield of its own, with strong connections to cultural history and public history.
What do these frameworks agree on? Most contemporary historians reject the idea that war can be studied in isolation from its social, cultural, and global contexts. The old operational assumption that campaigns can be analyzed purely in terms of command and tactics has been abandoned by all but a few specialists. There is also broad agreement that war is a gendered phenomenon, that non-Western perspectives matter, and that historians must be reflexive about their sources.
Where they disagree is on the relative weight of different causal factors. War and Society historians tend to privilege social structures and institutions; Cultural Military historians emphasize beliefs and identities; Global Military historians foreground transnational processes and power relations; Marxists insist on the primacy of class and economic forces. These disagreements are not signs of weakness but of a healthy field in which the central question—how are wars won and lost?—has been expanded to include a deeper set of questions: what makes war possible, what gives it meaning, and how does it shape the world long after the fighting stops?
