Wei Qiang: Engels' Interpretation of the "Battlefield of Ideas" from the Perspective of Historical Materialism
The 1853–1856 Oriental War (the Crimean War) entered a critical phase as this conflict, sweeping across the coasts of the Black Sea, brought the two million troops habitually maintained by Europe into sharp focus. At that time, significant disparities existed across various European nations regarding military organization, tactics, and morale. Furthermore, the state of military secrecy previously maintained due to international suspicion was broken, providing objective conditions for systematic comparative research. Engels is regarded as a "veritable encyclopedia" [1] of a theorist in the history of the development of Marxist military theory. In his military work The Armies of Europe, written in 1855 at the request of Marx, he conducted a panoramic comparative study of the militaries of major European powers. He expanded military struggle from a simple confrontation of force into a total struggle in which material and spiritual forces support one another, and the "material battlefield" and the "ideological battlefield" are intertwined.
"Ideological battlefield" is not an explicit term in The Armies of Europe, but rather an analytical thread running through the entire text. It points toward the construction of ideas, disciplinary regulation, spiritual identity, and the generation of morale within the military; it also points toward the spiritual comparison and competitive interplay of militaries across different nations, systems, and classes. From the perspective of historical materialism, Engels elucidated that the spiritual state, ideological characteristics, sense of discipline, and fighting will of an army are not abstract "inherited traits." Rather, they are forms of social consciousness shaped collectively by the mode of social production, class relations, historical traditions, cultural levels, and social systems. The ideological contestation, spiritual molding, and mobilization of morale in the military sphere constitute an "ideological battlefield" that runs parallel to the battlefield of physical force and profoundly constrains the outcome of war.
As a classic text applying historical materialism to analyze military phenomena, its core value lies not only in its systematic cataloging of the organizational structures, branch differences, and military practices of various 19th-century European armies. More importantly, it looks through the surface appearance of military development to reveal that the ideological battlefield—as a significant part of the social superstructure—is determined by the economic base, driven by class interests, and shaped by historical practice. In The Armies of Europe, Engels consistently adhered to an unshakeable principle: military spiritual characteristics and ideological conditions are, in the final analysis, determined by social existence and are the products of specific economic relations, class structures, and national lifestyles. This is the theoretical cornerstone of his analysis of the "ideological battlefield" and represents the fundamental point of divergence from idealist military views. In his comparison of European armies such as those of France, Germany, Britain, and Russia, Engels focused on the core category of national military character. He explicitly noted: "national character, historical tradition, and especially differing degrees of civilization, create many differences, so that the armies of each country have their own special strengths and weaknesses. Frenchmen and Hungarians, Englishmen and Italians, Russians and Germans, can all become equally excellent and efficient soldiers under certain conditions." "We can see at once what a military advantage a higher degree of civilization gives a country over its less developed neighbors." [2] The degree of civilization of any country or nation at different stages is not naturally formed but is the result of long-term shaping by that country’s geographical environment, economic structure, political system, and historical process. These discourses profoundly shattered the mystified interpretations of national military character found in the idealist conception of history.
The ideological battlefield is not an abstract, disconnected spiritual space, but a specialized field rooted in material social relations. The spiritual temperament, ideological orientation, and combat style of an army are, in essence, the concentrated projection of a country's or nation's social existence into the military sphere. Taking the Russian army of that time as an example, influenced by feudal serfdom, it developed characteristics of high soldier compliance, low requirements, and insufficient flexibility. Therefore, the national military traits—the agility and dash of the French army in the offensive, the stubborn tenacity of the British army in resistance, the German army’s comprehensive adaptation to military tasks, and the passive obedience of the Russian army—were not mysterious racial endowments. They were reflections of historically formed social consciousness within the military sphere of specific communities. The ideological battlefield is by no means a simple dispute over military ideas; it is a contest and interplay between different classes, social systems, and interest groups concerning the spiritual molding, value orientation, and political affiliation of specific armed forces. It is the concrete manifestation of historical materialism in the military sphere.
As a highly organized machine of violence, a military's primary ideological task is to form a unified will and absolute discipline. True military discipline is an ideological consciousness built upon the foundation of identity with the state, the system, and the national community. The primary function of the ideological battlefield is to condense and aggregate different individuals and dispersed wills into a military force possessing a unified will and unified thought, capable of unified action. Engels analyzed the disciplinary conditions of different European armies. In armies dominated by remnant feudal forces, disciplinary thought centered on "hierarchical oppression" and "deterrence through violence," maintaining military order by relying on means such as corporal punishment and torture. This not only caused physical pain to the soldiers but also left them with lifelong humiliation. This disciplinary thought originated from the feudal hierarchy; in essence, it was the oppression and control of soldiers by the ruling class, reflecting the constraints of feudal relations of production on military thought. In contrast, after the bourgeois revolutions, armies whose core disciplinary thought focused on the "contractual spirit" and "national duty"—though still possessing an essence of class oppression—broke the shackles of feudal hierarchy and emphasized the soldier's responsibility and obligation to the state. This disciplinary thought reflected the needs of capitalist relations of production and was the manifestation of bourgeois ideology in the military sphere.
Using the Austrian army as an example, Engels also pointed out that the condition of a multi-ethnic mixture was "a serious problem" for a military. For an army composed of soldiers from different nations, languages, and cultural backgrounds, "strict discipline maintained by the frequent application of hazel-stick lashes to the soldiers' buttocks" [3] might maintain surface order in peacetime. However, at critical moments—when national contradictions intensify, when war goals trigger controversy, or when morale is low—internal rifts are fully exposed. "In the army of a single state like Austria, there are six nations and two or three religious faiths. Then, the various tendencies existing in this army must inevitably collide with one another at a moment like the present, when every nation yearns to use its own forces freely." Engels noted that such an army requires "very special timing to fully exert its power," meaning that only when the goals of the war are consistent with the interests of each nation can a multi-ethnic mixed army coalesce into a whole. Once the war loses this "community of interests," the army is prone to internal disintegration. Therefore, whether an army can master its internal ideological battlefield directly determines its organizational effectiveness and combat success or failure. Discipline lacking ideological identity can only be passive and fragile, easily collapsing in actual combat; only discipline built on the foundation of ideological identity can be transformed into proactive and resilient combat effectiveness, becoming a strong guarantee of the ideological battlefield.
Morale and will, as the practical spiritual manifestations of the ideological battlefield, are the spiritual core of a military's combat effectiveness. Examining 19th-century European armies through historical materialism, Engels profoundly revealed that morale and will are rooted in social systems and class attributes, manifested in combat practice and disciplinary norms, and unified in the decisive role of the "human factor" in the outcome of war. Engels did not attribute morale and will to "innate bravery," but examined them within the context of material production and social relations. Comparing various European armies, he pointed out that the morale of feudal mercenaries was fragile because soldiers fought for pay and lacked spiritual belief; the morale of bourgeois armies was high because soldiers possessed a conscious sense of spiritual belonging. It can be seen that the essence of morale and will is the practical transformation of ideological identity, a vivid demonstration of the political consciousness of "for whom one fights" on the battlefield.
Morale and will, as the "offensive and defensive blades" of the ideological battlefield, can transform spiritual force into winning capability when equipment is inferior or the combat situation is difficult. In his analysis of European armies, Engels frequently used terms such as "spirit of solidarity," "spirit of bravery," "spirit of indomitable tenacity," "spirit of unwavering determination," and "the spirit of daring to fight and charge," illustrating that the end of physical confrontation is the contest of spiritual will. The prolonged resistance of the British army at Inkerman, where the few fought the many, is a typical manifestation of the fruits of the ideological battlefield. Engels recorded in The Armies of Europe: "Even the resolute and stubborn spirit of which the Russian army is so proud must be treated with considerable reservation, for at Inkerman, 8,000 British infantrymen, at a position not fully occupied and not strictly defended, were suddenly attacked; they engaged in bayonet combat with 15,000 attacking Russian troops, resisting for over four hours and stubbornly repelling one Russian attack after another. This battle certainly made the Russian army realize that in the aspect where they were strongest, they had met an even stronger opponent." This tenacious resistance was not merely a matter of continuous weapon supply or sustained physical strength, but a concentrated explosion of the British army's combat will. Similarly, the resilient endurance of the Russian army and the offensive initiative of the French army are not described by Engels as abstract courage, but as practical manifestations of long-term tempering on the ideological battlefield. Morale and will are the concentrated explosions of ideological force against material hardship. An army without an ideological soul, morale, or will, even if well-equipped, will collapse at critical moments; whereas an army with firm ideology, high morale, and strong will, even if material conditions are temporarily inferior, can use spiritual force to bridge the gap and win the initiative on the battlefield. Maintaining high morale and firm combat will allows spiritual force to be transformed into "hardcore" combat effectiveness, fully demonstrating the power of the truth in Marxist military theory that "it is people, not things, that ultimately decide the outcome of a war."
From the analysis of 19th-century European armies in The Armies of Europe to contemporary military practice, Engels’ profound discourse on the "ideological battlefield" transcends time and space, still possessing powerful theoretical charm. This inspires us: no matter how technology develops, the subject of war is always the human being; the initiative on the ideological battlefield is just as important as the initiative on the battlefield of force—perhaps even more fundamental. The struggle for the hearts and minds of the people, the mastery of the leadership of ideology, and the cultivation of spiritual cohesion remain the core issues of military struggle.
