International Relations Theories and World War I

By /

The cataclysmic events of World War I marked a turning point in global history, redefining the way nations interact, engage, and negotiate power. As the world grappled with the unprecedented devastation, scholars and policymakers sought to understand the underlying causes of the conflict and its implications for future international relations. The resulting intellectual efforts gave rise to diverse theories that attempt to explain the dynamics of state behavior, the nature of power, and the mechanisms of war and peace. From the cold calculations of realism to the aspirational ideals of liberalism, and from the economic critiques of Marxism to the nuanced perspectives of constructivism, these theories have profoundly shaped our understanding of the world order.

World War I, often referred to as “The Great War,” was not merely a series of battles; it was a complex interplay of political ambitions, economic interests, ideological rivalries, and social upheavals. The war’s origins and consequences have been analyzed through various theoretical lenses, each offering unique insights into the motivations of states and the structural forces at play. Realism, with its emphasis on power politics and the anarchic nature of the international system, provides a stark explanation of the competitive and conflict-prone behavior of nations. In contrast, liberalism highlights the possibilities of cooperation, institutional frameworks, and the role of democratic governance in mitigating conflict.

Marxism introduces a critical perspective, arguing that the war was driven by capitalist rivalries and the exploitation of class divisions. Constructivism shifts the focus to the importance of ideas, identities, and social constructs in shaping international interactions, while critical theories challenge traditional paradigms and underscore the need for transformative approaches to global politics. Neorealism and neoliberalism, as modern iterations of their classical counterparts, delve deeper into the structural and institutional dimensions of state behavior, offering refined analyses of power dynamics and interdependence.

This article delves into these foundational theories of international relations, examining their relevance and application to the study of World War I. By exploring the theoretical underpinnings and their interpretations of the war’s causes and consequences, we aim to provide a comprehensive understanding of how these perspectives illuminate the complexities of international politics during one of history’s most pivotal eras. Whether through the lens of realism’s grim pragmatism or liberalism’s hope for a better world, the theories of international relations continue to offer valuable frameworks for interpreting the past and navigating the challenges of the present and future.

Realism

Realism is a foundational theory in international relations that views the international system as inherently anarchic, meaning there is no overarching authority to enforce rules or prevent conflict. In this anarchic system:

  1. States are the primary actors: They operate as rational entities, pursuing their survival and maximizing power.
  2. Self-help is essential: States cannot rely on others for security, leading to a focus on military and economic strength.
  3. Power politics dominate: Relations between states are governed by the struggle for power and influence, with competition often resulting in conflict.
  4. Conflict is inevitable: The lack of a central authority and the constant pursuit of power create conditions where war and conflict are natural outcomes.

Realism offers a powerful lens for understanding the causes, dynamics, and consequences of World War I. By applying its principles, we can analyze the behavior of states and the structural forces that led to the conflict.

1. Anarchy and the Security Dilemma: The anarchic nature of the international system created an environment of mistrust among major powers. Efforts by states to ensure their own security—such as Germany’s military buildup and Britain’s naval expansion—provoked countermeasures by rival nations. This security dilemma intensified tensions and set the stage for war, as defensive actions were perceived as offensive threats.

2. The Balance of Power: The balance of power theory, central to realism, explains how alliances formed to counteract perceived threats. The Triple Alliance (Germany, Austria-Hungary, and Italy) and the Triple Entente (France, Russia, and the United Kingdom) were designed to prevent any single power from dominating Europe. However, these alliances also created rigid blocs that escalated the conflict once it began, transforming a regional dispute into a global war.

3. National Interest and Power Competition: Realism posits that states act in their national interest, seeking to maximize power and influence. In the years leading up to World War I:

  • Germany pursued Weltpolitik, aiming to assert itself as a global power, challenging Britain’s dominance.
  • Austria-Hungary sought to suppress nationalist movements in the Balkans to preserve its empire.
  • Russia aimed to expand its influence in Eastern Europe and protect Slavic nations like Serbia.
  • France sought to recover Alsace-Lorraine and counter German power.

These competing interests fueled rivalries and increased the likelihood of conflict.

4. Conflict as an Inevitable Outcome: Realism argues that war is a natural result of the anarchic system and power struggles. The assassination of Archduke Franz Ferdinand was merely the spark that ignited underlying tensions driven by systemic forces. The war reflected the realist belief that competition for dominance and security inevitably leads to conflict.

5. The Treaty of Versailles: The harsh terms of the Treaty of Versailles can also be understood through realism. The victors, primarily Britain and France, imposed punitive measures on Germany to weaken it as a future threat. This aligns with the realist view that states act to consolidate power and eliminate challenges, even at the risk of sowing seeds for future conflicts.

In this way Realism provides a comprehensive framework for analyzing World War I by emphasizing the anarchic nature of the international system, the pursuit of power, and the inevitability of conflict. The war exemplifies how states, driven by national interests and constrained by an anarchic system, engaged in a catastrophic struggle for dominance. Realism not only helps explain the origins and dynamics of World War I but also offers enduring lessons on the challenges of maintaining peace in an inherently competitive global order.

Liberalism

Liberalism is a political and philosophical theory emphasizing individual freedoms, democratic governance, free markets, and the rule of law. In the context of international relations, liberalism focuses on cooperation, institutions, and shared interests among states. Key assumptions include:

  1. Human Rationality and Progress: Humans and states are capable of rational decision-making, fostering cooperation for mutual benefit.
  2. Interdependence: Economic, political, and cultural connections between states reduce the likelihood of war.
  3. Role of Institutions: International institutions and norms help mediate conflicts and encourage collaboration.
  4. Democratic Peace Theory: Democracies are less likely to go to war with one another due to shared values and accountability mechanisms.

Liberalism’s principles provide a framework for understanding both the causes of World War I and the post-war efforts to prevent future conflicts:

Causes of World War I:

Liberalism highlights failures in cooperation and interdependence that contributed to the outbreak of war:

  1. Weak International Institutions: The lack of effective international organizations to mediate disputes left states to resolve conflicts unilaterally or through alliances, escalating tensions.
  2. Economic Nationalism: While liberalism advocates for interdependence to promote peace, the period leading up to WWI was marked by economic protectionism and competitive colonialism, fostering rivalries.
  3. Authoritarian States: The presence of autocratic empires (e.g., Germany, Austria-Hungary, and Russia) limited democratic accountability, which liberal theorists argue makes states more prone to war.

Liberalism in Post-War Efforts:

After WWI, liberal ideals significantly influenced attempts to reshape the international system to prevent future conflicts:

  1. The League of Nations: Proposed by U.S. President Woodrow Wilson in his Fourteen Points, the League was envisioned as an international organization where states could resolve disputes peacefully and collectively deter aggression.
  2. Self-Determination: Liberalism influenced the push for national self-determination, aiming to reduce imperialist conflicts by aligning state boundaries with ethnic and cultural identities.
  3. Disarmament and Open Diplomacy: Liberal principles guided efforts to reduce arms races and encourage transparency in international agreements.

Liberalism’s influence after WWI was limited due to:

  1. U.S. Isolationism: The U.S. Senate’s refusal to join the League of Nations undermined its effectiveness.
  2. Structural Weakness of the League: The League lacked enforcement mechanisms and failed to prevent aggressive actions by revisionist powers in the interwar period.
  3. Economic Turmoil: The Great Depression and reparations policies created conditions that liberal institutions struggled to manage, leading to renewed conflict.

In this way, Liberalism provides valuable insights into the dynamics of WWI and its aftermath. While its principles informed efforts to build a more cooperative and peaceful international system, the limitations of liberal approaches during the interwar period highlight the challenges of implementing these ideals in a fragmented and unequal world order.

Marxism

Marxism, rooted in the works of Karl Marx and Friedrich Engels, is a socio-economic theory that views history as a struggle between classes, primarily the bourgeoisie (owners of capital) and the proletariat (working class). Its key principles include:

  1. Class Struggle: The driving force of historical change is the conflict between economic classes.
  2. Capitalism and Imperialism: Capitalism inherently leads to inequality, exploitation, and crises, pushing nations to seek new markets and resources through imperialism.
  3. Economic Determinism: Economic structures underpin political and social institutions, shaping state behavior and international relations.
  4. Revolutionary Change: Overthrowing capitalist systems is seen as essential to achieving a classless and equitable society.

Marxism provides a lens to analyze WWI by focusing on the economic and class dynamics that led to the war and its consequences:

Causes of World War I:

From a Marxist perspective, WWI was a result of the inherent contradictions of capitalism and imperialism:

  1. Imperialist Rivalries:
    • Advanced capitalist states sought new markets, raw materials, and investment opportunities, leading to intense competition.
    • The scramble for colonies, particularly in Africa and Asia, created tensions among major powers such as Britain, France, Germany, and Austria-Hungary.
    • Lenin described the war as the “highest stage of capitalism,” where imperialist states clashed to divide the world into spheres of influence.
  2. Economic Inequalities:
    • The exploitation of the proletariat within industrialized nations created social unrest, distracting attention from domestic issues by externalizing conflicts through war.
    • Capitalists, particularly in industries like arms manufacturing, benefited economically from war preparations, reinforcing militarism.
  3. Alliance Systems and Militarization:
    • Marxists argue that these systems reflected the interests of capitalist elites rather than the general populace.
    • Armament industries, controlled by the bourgeoisie, pushed for increased production, leading to a climate ripe for conflict.

Impact of World War I:

Marxists analyze the consequences of WWI through the lens of class struggle and economic exploitation:

  1. Proletarian Suffering:
    • The working class bore the brunt of the war through mass conscription, deaths, and economic hardship, while capitalist elites profited.
    • Food shortages, inflation, and deteriorating living conditions exacerbated class tensions.
  2. Revolutionary Movements:
    • The Russian Revolution of 1917 exemplified Marxist predictions about war intensifying class struggle. The Bolsheviks, inspired by Marxist ideology, overthrew the Tsarist regime and established the first socialist state.
    • The war also catalyzed labor movements and uprisings in other countries, such as the German Revolution of 1918–1919.
  3. Colonial Exploitation:
    • Marxists highlight the increased exploitation of colonies during the war, as imperial powers extracted resources and manpower to sustain their war efforts.

Post-War Analysis:

Marxists view the Treaty of Versailles and the post-war order as reinforcing capitalist and imperialist structures:

  1. Reparations and Economic Exploitation:
    • The harsh terms imposed on Germany aimed to protect the interests of victorious capitalist states, sowing the seeds for future conflict.
  2. Persistence of Imperialism:
    • Despite the League of Nations, colonial domination continued, and economic exploitation of the Global South intensified.

Limitations and Criticisms:

While Marxism offers a compelling critique of capitalism and imperialism, its application to WWI is not without challenges:

  1. Reductionism:
    • Critics argue that Marxism overly simplifies complex political, cultural, and nationalistic factors, attributing all conflicts to economic causes.
  2. Revolutionary Outcomes:
    • Although the Russian Revolution aligned with Marxist predictions, revolutions in other countries failed to materialize or were suppressed, limiting the theory’s explanatory power.

Marxism frames World War I as a product of capitalist and imperialist contradictions, emphasizing the economic roots of conflict and the exploitation of the working class. It also highlights the revolutionary potential of war in exposing and challenging these systems. While its analysis captures key economic dynamics, it may understate the roles of nationalism, ideology, and other non-economic factors.

Constructivism

Constructivism is an approach in international relations emphasizing the importance of ideas, norms, identities, and social interactions in shaping the behavior of states and other actors. Its core tenets include:

  1. Socially Constructed Reality: The international system is not objectively given but constructed through shared ideas, beliefs, and social practices.
  2. Importance of Norms and Identity: State behavior is influenced by collective norms, identities, and perceptions rather than solely by material power or economic factors.
  3. Mutual Constitution: States and the international system shape and are shaped by each other through interaction.
  4. Change through Ideas: Norms and identities are malleable and can evolve, altering the nature of international relations.

Constructivism offers insights into the role of ideas, norms, and identities in the causes, conduct, and consequences of World War I:

Causes of World War I:

From a constructivist perspective, WWI was not merely the result of structural factors (e.g., alliances, power dynamics) but also of socially constructed norms and identities:

  1. Nationalism:
    • National identity and nationalism played a pivotal role in fostering rivalry and mistrust.
    • For example, Serbian nationalism threatened the Austro-Hungarian Empire’s multi-ethnic structure, contributing to tensions that led to the assassination of Archduke Franz Ferdinand.
    • Nationalistic fervor across Europe created a climate where war was seen as a legitimate means of asserting national superiority.
  2. Militarism and Cultural Norms:
    • Militaristic values, such as the glorification of war and the belief in its necessity to resolve disputes, permeated European societies.
    • The concept of honor and prestige drove states to adopt aggressive stances, as retreat or compromise was perceived as weakness.
  3. Alliance System as Social Structure:
    • Alliances like the Triple Entente and Triple Alliance were not just strategic arrangements but also reflected shared norms and mutual perceptions of threat or friendship.
    • The “othering” of rivals (e.g., framing Germany as a threat by Britain and France) deepened divides.
  4. Perceptions and Miscommunication:
    • Misinterpretations of intentions among states, shaped by preexisting biases and identities, exacerbated tensions.
    • For instance, Germany’s fear of encirclement by the Entente powers was a construct of its identity as a rising power seeking its “place in the sun.”

Conduct of World War I:

  1. Framing of the War:
    • The war was framed as a moral and existential struggle by many governments, reinforcing public support. For example, Britain portrayed itself as defending “civilization” against German aggression.
    • Propaganda shaped identities and sustained the belief that the war was justified.
  2. Social Solidarity in Wartime:
    • National unity and the expectation to support the war effort were constructed through shared narratives of duty and sacrifice.
  3. Dehumanization of the Enemy:
    • Social constructs of the enemy as barbaric or inferior justified violence and prolonged the conflict.

Consequences of World War I:

  1. Redefinition of Norms:
    • The war’s devastation challenged prewar norms about the legitimacy and utility of war, leading to a shift toward pacifist movements and the creation of the League of Nations.
    • The idea of national self-determination, championed by U.S. President Woodrow Wilson, reshaped post-war diplomacy and the international order.
  2. Identity Shifts:
    • The collapse of empires like Austria-Hungary, the Ottoman Empire, and Russia was partially due to the inability to reconcile diverse national identities within a single political framework.
    • The war also catalyzed the formation of new national identities in Europe and beyond.
  3. Legacy of Collective Memory:
    • Collective memory of WWI, as “The Great War,” became a cultural touchstone, influencing interwar norms and the policies of nations in the lead-up to World War II.

Strengths of Constructivist Analysis:

  • Emphasizes the role of ideas, perceptions, and norms in shaping the war’s dynamics.
  • Provides a nuanced understanding of how identities and shared beliefs influenced state behavior.
  • Highlights the importance of non-material factors, such as nationalism and propaganda, in the escalation and conduct of war.

Limitations and Criticisms:

  • Critics argue that constructivism can be overly focused on ideas, neglecting material factors like economic interests and military capabilities.
  • The approach sometimes lacks predictive power, as it relies on interpreting socially constructed phenomena retrospectively.

Constructivism enriches the understanding of World War I by focusing on how ideas, identities, and norms shaped the causes, conduct, and aftermath of the conflict. While it may not fully account for material factors, it offers a valuable perspective on the interplay between social constructs and international relations during this transformative period.

Critical Theories

Critical theories in international relations, including Marxism, Feminism, Postcolonialism, and others, challenge the dominant paradigms of mainstream political thought, such as realism and liberalism. These theories emphasize the need to understand and transform the existing power structures and inequalities that shape global politics. Critical theorists argue that international relations are influenced by social, economic, and cultural dynamics that perpetuate exploitation, oppression, and inequality. The key ideas include:

  1. Power and Inequality: International relations are shaped by unequal power relations, often favoring dominant states or groups.
  2. Historical Context: Understanding global politics requires examining historical processes and how they have led to current systems of oppression, domination, and exploitation.
  3. Emphasis on Social Justice: Critical theories focus on addressing the underlying causes of inequality and injustice in the international system.
  4. Challenge to Mainstream Theories: Critical theories seek to dismantle the status quo, questioning assumptions in liberal, realist, and other dominant frameworks.

Critical theories provide a variety of perspectives on the causes, conduct, and consequences of World War I, focusing on issues of class, gender, race, empire, and historical inequality.

1. Marxist Analysis (Critical of Capitalism and Imperialism):

Marxist theory, a prominent critical approach, sees World War I as an inevitable outcome of capitalist expansion and imperialist competition.

Causes of the War:

  • Imperialism and Capitalism: According to Marxists, imperialist powers, particularly Britain, France, and Germany, competed for colonial resources, markets, and influence. The war was driven by the economic interests of the bourgeoisie (capitalist elites) seeking to expand their empires and control global resources.
  • Class Struggle: The war diverted attention from class struggles within countries by uniting the working classes under nationalistic banners. Marxists argue that the elites used the war to solidify their power and suppress domestic dissent.

Conduct and Consequences:

  • Exploitation of the Proletariat: Marxists argue that the war exacerbated the exploitation of the working class, who fought and died while the capitalist elite reaped the benefits, particularly through the arms industry.
  • Post-War Economic Exploitation: The Treaty of Versailles, which placed heavy reparations on Germany, was seen by Marxists as a means to reinforce capitalist interests and prevent the spread of socialist revolution in Europe.

2. Feminist Theory (Critical of Gender Norms):

Feminist critical theory challenges traditional gender roles and the exclusion of women from the analysis of international relations. It argues that traditional views of war and peace often ignore the gendered dimensions of conflict.

Causes of the War:

  • Patriarchy and Masculinity: Feminists argue that the glorification of war and the construction of masculinity played a crucial role in shaping the rhetoric and practice of war. The idea of men as protectors of the nation and the emphasis on national honor and glory reinforced aggressive attitudes.
  • Exclusion of Women’s Voices: Women were largely excluded from the decision-making processes that led to the war, and their experiences and contributions were marginalized in the post-war narrative.

Impact of the War:

  • Women in Wartime: Although women were excluded from combat, they played critical roles in supporting the war effort, working in munitions factories, nursing, and taking on roles traditionally held by men. This challenged traditional gender roles and laid the foundation for the later women’s suffrage movements.
  • Post-War Gender Inequality: The aftermath of WWI saw the continuation of gendered inequalities in many countries, despite women gaining suffrage in some nations. The war reinforced existing patriarchal structures in many aspects of society.

3. Postcolonial Theory (Critical of Empire and Colonialism):

Postcolonial theory focuses on the effects of colonialism and empire on both the colonized and the colonizers. It critiques the imperialist powers that shaped global politics, including the context of World War I.

Causes of the War:

  • Colonial Rivalry: The imperial powers, especially European nations like Britain, France, and Germany, were in competition for colonies in Africa, Asia, and the Pacific. These imperial ambitions played a key role in the outbreak of conflict.
  • Exploitation of Colonies: Colonized peoples were often forced to participate in the war effort, providing resources and manpower for the imperial powers, yet they were denied any political rights or recognition.

Impact of the War:

  • Colonial Contributions: Millions of soldiers from colonies (e.g., India, Africa, and the Caribbean) fought for the European powers, but they were often treated as second-class citizens and received little recognition or reward for their sacrifices.
  • Post-War Colonial Unrest: The war set the stage for decolonization movements. Many colonies that contributed to the war effort began to demand independence and greater political rights, leading to a rise in anti-colonial sentiment and movements, particularly in Asia and Africa.

4. Critical Theory (Frankfurt School):

Critical theorists from the Frankfurt School, like Theodor Adorno and Max Horkheimer, focused on the role of ideology, culture, and mass media in shaping public consciousness and justifying war.

Causes of the War:

  • Ideological Manipulation: Critical theorists argue that war is often legitimized through ideological manipulation. The war was framed as a moral necessity, with nationalist and patriotic rhetoric used to justify the violence.
  • Rise of Authoritarianism: The war’s aftermath saw the rise of authoritarian regimes in Europe, including fascism in Italy and National Socialism in Germany. Critical theorists argue that these regimes capitalized on the trauma and instability caused by the war to justify oppressive ideologies.

Consequences of the War:

  • Cultural Trauma and Ideological Shifts: The horrors of WWI had a profound impact on European culture and intellectual life, leading to a rejection of Enlightenment ideals in favor of more radical critiques of modernity.
  • The Rise of Fascism and Totalitarianism: Critical theorists also analyze how the conditions created by the war, including economic depression and social instability, contributed to the rise of fascist ideologies that rejected liberal democracy and embraced authoritarian, nationalist ideologies.

Strengths of Critical Theory Analysis:

  • Emphasizes Power Structures: Critical theories highlight the role of imperialism, capitalism, patriarchy, and other structures of power in shaping international relations.
  • Focus on Social Justice: These theories provide a platform for marginalized voices, including women, colonized peoples, and working classes.
  • Challenging the Status Quo: Critical theories offer a critique of the prevailing political and social systems, advocating for transformation toward more just and equitable global relations.

Limitations and Criticisms:

  • Overemphasis on Ideology: Some critics argue that critical theories focus too much on ideological factors and not enough on material realities like economics and military strategy.
  • Complexity and Ambiguity: Critical theories can be difficult to apply in practical policy terms, as they often reject traditional models of international relations and provide more abstract analyses.

Critical theories offer a rich and diverse perspective on World War I, focusing on the role of power, oppression, and inequality in shaping the causes and consequences of the conflict. By emphasizing the social, economic, and cultural structures that underpin international relations, critical theorists provide a deeper understanding of the war and its aftermath, while also challenging the dominant narratives of global politics.

Neorealism (Structural Realism)

Neo-realism, also known as structural realism, is an evolution of classical realism in international relations theory. Developed primarily by Kenneth Waltz in his 1979 book Theory of International Politics, neo-realism focuses on the structure of the international system as the primary driver of state behavior, rather than human nature or the specific actions of individual leaders. The key tenets of neo-realism are:

  1. Anarchy: The international system is anarchic, meaning there is no central authority or overarching government above states. This lack of global governance leads to a self-help system where states must rely on their own resources for survival and security.
  2. State Behavior: States are the central actors in international relations and act in their national interest, primarily focused on survival, which often translates into security concerns.
  3. Balance of Power: States seek to maintain a balance of power to prevent any one state from becoming too dominant. If a state becomes too powerful, other states will balance against it either through alliances or military buildup.
  4. Structure of the International System: The structure of the international system determines state behavior. The distribution of power across states influences how they interact. In a multipolar system, for example, balancing behavior is more common than in a bipolar system, where rivalry between two superpowers tends to dominate.

Neo-realism offers a structural and systemic perspective on the causes of World War I, focusing on the anarchic international system and the dynamics of power politics. Neo-realists argue that the war was not solely the result of specific events or personalities, but rather an outcome of the underlying structure of the international system and the behavior of states within that system.

1. The Balance of Power and the Pre-War System:

  • Multipolarity and Rivalry: In the period leading up to World War I, Europe was characterized by a multipolar system, where multiple great powers (Britain, France, Germany, Austria-Hungary, and Russia) competed for influence and power. Neo-realists argue that this multipolar structure created insecurity, as each state feared the rise of a dominant power and sought to secure its own position.
  • Shifting Alliances: The system of alliances, which included the Triple Alliance (Germany, Austria-Hungary, and Italy) and the Triple Entente (France, Britain, and Russia), reflected attempts by states to balance against the perceived threat of rival powers. Neo-realists argue that these alliances, rather than promoting peace, created a situation where the failure of one power could trigger a large-scale war, as alliances dragged states into conflict.

2. The Security Dilemma:

  • Arms Buildup and Mutual Suspicion: Neo-realism emphasizes the security dilemma, where states, seeking to enhance their own security, inadvertently provoke insecurity in other states. For instance, Germany’s military buildup and rapid industrialization during the early 20th century were seen as threatening by other European powers. In response, Britain and France expanded their own military capabilities, which in turn heightened German fears of encirclement, prompting further military development.
  • Escalation of Tensions: As each state sought to increase its own security, the overall level of militarization and tension across Europe rose, leading to an environment where war became more likely. The outbreak of World War I was, in part, a result of this spiraling insecurity and competition among the great powers.

3. Anarchy and the Lack of Global Authority:

  • Absence of a Central Authority: Neo-realists argue that the lack of a higher authority to mediate disputes between states in an anarchic system contributed to the outbreak of war. In a world without a global government or central arbiter, states relied on their own power and diplomacy to settle conflicts, and the absence of effective mechanisms for conflict resolution made war more likely.
  • Diplomacy and Deterrence Failures: The inability of diplomacy to prevent war can be explained by the absence of a central authority capable of enforcing agreements or offering credible guarantees to weaker states. When tensions escalated after the assassination of Archduke Franz Ferdinand, the inability of diplomatic efforts to avert war showed the limits of negotiations in an anarchic international system.

4. Germany’s Position and the Fear of Encirclement:

  • German Expansionism: Germany’s foreign policy, especially under Kaiser Wilhelm II, was driven by the desire to challenge the established power structures and secure its “place in the sun” by expanding its influence, particularly in Europe and overseas colonies. Neo-realists argue that Germany’s quest for greater power led to increased insecurity among its neighbors, particularly France and Russia, who began to form alliances against it.
  • The Fear of Encirclement: Germany’s strategic priority was to avoid being encircled by hostile powers. The alliance between France, Russia, and Britain (the Entente Powers) was perceived by Germany as a threat. The fear of encirclement led Germany to adopt a preemptive strategy, such as the Schlieffen Plan, which aimed to quickly defeat France and then turn to Russia to avoid a two-front war. The resulting escalation, triggered by the assassination in Sarajevo, was partly the product of Germany’s efforts to secure its position in an increasingly hostile environment.

5. The Role of Great Power Rivalries:

  • Competition for Influence and Prestige: Neo-realists highlight the role of power competition and prestige in shaping the behavior of states before and during the war. States like Britain and Germany were in competition for global dominance, particularly in naval power, leading to the naval arms race. Britain’s fear of Germany’s growing naval capabilities and its potential to challenge British supremacy in the seas was a critical factor in the lead-up to the war.
  • Austria-Hungary and Russia: Both Austria-Hungary and Russia were engaged in imperial and territorial competition in the Balkans, a region that was a flashpoint for tensions. Austria-Hungary feared Russian expansion in the Balkans and was also concerned about the rising nationalism among Slavic peoples, which could threaten the stability of its empire. Similarly, Russia sought to extend its influence in the region, further exacerbating tensions between the two powers.

Strengths of Neo-Realist Analysis:

  • Focus on Structural Factors: Neo-realism offers a systematic, structural explanation of the causes of World War I, emphasizing the role of the international system, the balance of power, and the behavior of states.
  • Emphasis on Power and Security: Neo-realism’s focus on the pursuit of power and security helps explain why states went to war despite the devastating consequences.
  • Predictive Power: Neo-realism’s focus on the distribution of power can offer insights into the future behavior of states, particularly in the context of balancing behavior and shifts in power dynamics.

Limitations and Criticisms:

  • Overemphasis on Structure: Critics argue that neo-realism tends to downplay the role of individual leaders, ideologies, and domestic factors that can also significantly influence state behavior.
  • Reductionist: Some critics argue that neo-realism’s focus on power and security may overlook the complexity of historical events and the non-material factors (e.g., nationalism, ideology) that contributed to the war.
  • Deterministic: Neo-realism’s view of international relations as governed by structural imperatives can be seen as deterministic, potentially ignoring the capacity for agency, change, and the impact of human decision-making.

Neo-realism provides a compelling structural explanation for the causes of World War I by emphasizing the anarchic international system, the balance of power, and the security dilemma. It argues that the war was a consequence of states’ efforts to secure their survival in an environment of intense competition and uncertainty. While it highlights important systemic factors, neo-realism is often criticized for underestimating the role of non-structural elements like individual agency and ideological forces.

Neoliberalism

Neo-liberalism in international relations theory builds on classical liberalism but incorporates a more systematic, institutional approach. While classical liberalism emphasizes the importance of individual freedoms, democracy, and economic interdependence, neo-liberalism focuses on the role of international institutions and the ways in which states and non-state actors cooperate to manage conflicts and promote peace in the anarchic international system. The key premises of neo-liberalism include:

  1. Cooperation and Interdependence: Neo-liberalism argues that despite the anarchic nature of the international system, cooperation between states is possible and beneficial. States can find ways to cooperate in areas such as trade, environmental policy, and security through institutions that manage collective action.
  2. International Institutions: Neo-liberals believe that international institutions, such as the United Nations (UN), the World Trade Organization (WTO), and others, can help manage state behavior and mitigate the risks of conflict by providing platforms for communication, negotiation, and the enforcement of agreements.
  3. Economic Interdependence: A major assumption of neo-liberalism is that increasing economic interdependence between states—through trade, investment, and shared economic interests—can reduce the likelihood of conflict. States that are economically intertwined have a greater stake in maintaining peaceful relations because war would disrupt mutual economic benefits.
  4. Rational Actors and Long-Term Gains: Neo-liberalism assumes that states are rational actors seeking to maximize their long-term welfare and security. States will engage in cooperation and avoid war when they recognize that the benefits of peaceful relations outweigh the costs of conflict.

Neo-liberalism offers a somewhat contrasting explanation for the causes of World War I compared to other theories like realism or constructivism. It focuses on the failure of international institutions, economic interdependence, and the lack of cooperation between states as contributing factors to the war. Although neo-liberalism emphasizes the potential for cooperation and peace, the outbreak of World War I can be seen as the result of the breakdown of cooperative efforts and the failure of institutional frameworks to prevent war.

1. The Failure of Economic Interdependence:

  • Rivalry, Not Interdependence: One of the core tenets of neo-liberalism is that economic interdependence reduces the likelihood of war. In the early 20th century, the European powers were economically connected through trade, investment, and colonial empires. However, these economic ties did not prevent the outbreak of war. Instead, neo-liberal theorists might argue that the intense economic rivalries and protectionist policies among major powers like Germany, Britain, and France contributed to the escalation of tensions. The trade and economic competition between states, rather than fostering peace, may have created deeper rivalries, especially as Germany’s industrial growth threatened the established powers.
  • Colonialism and Economic Competition: European powers were also competing for global economic dominance, particularly in Africa and Asia. The quest for colonies and resources outside of Europe increased tensions between the imperial powers. In this case, the lack of shared economic interests (as opposed to the cooperative model of neo-liberalism) fueled competition and contributed to the war’s outbreak.

2. The Absence of Effective International Institutions:

  • Lack of Mechanisms for Cooperation: Neo-liberalism emphasizes the importance of international institutions in fostering cooperation and preventing conflict. Before World War I, there were limited institutional mechanisms for resolving disputes and preventing escalation. The Concert of Europe (an informal system of diplomacy and cooperation among European powers) had been weakened by the late 19th and early 20th centuries, and the major powers were unable to effectively manage their rivalries or peacefully resolve crises. Despite some diplomatic efforts, the lack of formal, binding institutions for conflict resolution meant that disputes were often resolved through militarized diplomacy rather than negotiation.
  • Diplomatic Failures: Key moments leading up to World War I, such as the crises in Morocco (1905 and 1911), the Balkan Wars, and the assassination of Archduke Franz Ferdinand, were characterized by failed diplomatic efforts to de-escalate tensions. Neo-liberalism would argue that the absence of an effective international institution capable of mediating these conflicts and fostering cooperation contributed to the inability to avoid war.

3. The Role of Alliances and Institutionalized Cooperation:

  • Unstable Alliances: Neo-liberalism argues that institutions can facilitate cooperation, but in the case of World War I, the system of alliances (such as the Triple Entente and Triple Alliance) was less about promoting cooperation and more about balancing power. The alliance system, rather than fostering trust and peace, created an environment where small conflicts could escalate into global war. These alliances were intended to provide security and prevent war, but in practice, they created a network of obligations that drew states into the conflict.
  • Institutionalized Security Concerns: Neo-liberals would argue that the alliance system failed because it did not provide sufficient mechanisms for resolving disputes diplomatically and instead institutionalized insecurity. Countries like Germany, Austria-Hungary, Russia, and France acted based on the premise of self-help and maintaining security, rather than through cooperative frameworks that could have provided alternatives to war.

4. Mismanagement of Economic and Diplomatic Opportunities:

  • Opportunity for Cooperation: Neo-liberal theorists might point out that there were missed opportunities for cooperation between the great powers, especially regarding economic integration and diplomatic negotiation. For instance, after the First and Second Moroccan Crises, there was an opportunity for greater diplomatic cooperation, yet mistrust and national rivalries undermined efforts for a lasting peace.
  • Lack of Global Governance: A neo-liberal analysis of World War I might suggest that if there had been more robust international institutions—such as a more powerful League of Nations or earlier forms of collective security agreements—states might have been more likely to resolve their disputes peacefully. The international system in 1914 lacked mechanisms for governance that could have mitigated the pressures of nationalism, imperialism, and militarism, all of which contributed to the war.

5. The Role of Rational Actors and Misperception:

  • Rational Calculation: Neo-liberalism assumes that states are rational actors seeking to maximize their welfare. However, World War I presents a case where states, despite their rational calculation of power and security, misjudged the consequences of their actions. Neo-liberalism would argue that states, particularly Germany, Austria-Hungary, and Russia, were acting based on rational calculations to secure their national interests, but failed to fully account for the catastrophic potential of escalating tensions. The war was, in part, a result of rational actors miscalculating the benefits and risks of war, compounded by poor communication and the breakdown of cooperative diplomacy.

Strengths of Neo-Liberal Analysis:

  • Emphasizes Cooperation: Neo-liberalism focuses on how states could have cooperated to avoid conflict and the role of international institutions in maintaining peace.
  • Systemic View of Economic and Diplomatic Interdependence: The theory highlights the importance of economic ties and diplomatic cooperation, which can help prevent conflict.
  • Attention to Institutions: Neo-liberalism stresses the importance of international institutions in fostering cooperation and resolving disputes, which can be applied to understanding why their absence or weakness contributed to the outbreak of war.

Limitations and Criticisms:

  • Overemphasis on Cooperation: Critics argue that neo-liberalism is overly optimistic about the potential for cooperation, especially in the face of intense national rivalries and historical power imbalances.
  • Lack of Attention to Power Politics: Neo-liberalism may understate the importance of power politics and security concerns, which can sometimes override the benefits of cooperation.
  • Historical Context: Some critics argue that neo-liberalism’s focus on cooperation and institutions might not adequately explain the deeper, historical causes of the war, such as nationalism, imperialism, and militarism.

Neo-liberalism offers a perspective on World War I that focuses on the failure of international institutions and the breakdown of economic interdependence and cooperation. It highlights the missed opportunities for diplomacy and the lack of effective mechanisms for conflict resolution. While neo-liberalism emphasizes the potential for cooperation and peaceful resolution of disputes, it also acknowledges that the international system of 1914 lacked the institutions and frameworks that might have prevented the war. The outbreak of World War I, from a neo-liberal perspective, can be seen as the result of institutional failure, economic rivalry, and missed opportunities for cooperation.

Conclusion

The application of various International Relations (IR) theories to the causes of World War I reveals the complex, multifaceted nature of this catastrophic conflict. Each theory offers a unique lens through which to understand the driving forces behind the war, from the aggressive competition for power and security in the anarchic international system highlighted by neo-realism, to the failure of economic interdependence and international institutions emphasized by neo-liberalism. The constructivist view adds yet another layer by focusing on the role of ideologies, identities, and perceptions that shaped the decisions of statesmen, while Marxism underscores the economic and class-based tensions that underpin the global system. Finally, critical theories challenge the very structure of international relations, questioning the imperialist, capitalist, and hierarchical systems that, in their view, perpetuated conflict and inequality, ultimately making war an almost inevitable outcome.

While each theory provides valuable insights, the complexity of World War I defies easy reduction to a single explanatory framework. The war was the result of an intricate interplay between structural factors—such as the balance of power and economic competition—alongside individual choices, misperceptions, and historical contingencies. The failure of diplomacy and the inability to resolve tensions through cooperative means underscored the weaknesses of the international system at the time. Nationalism, militarism, imperialism, and the fragility of alliances set the stage for conflict, but the ultimate spark—often traced back to the assassination of Archduke Franz Ferdinand—was itself a symptom of a world teetering on the edge of war.

The theory of neo-realism, with its emphasis on the anarchic structure of the international system and the logic of power, helps explain why states were caught in a cycle of distrust and competition. The system of alliances, rather than providing security, became a mechanism that dragged multiple states into a conflict that may otherwise have remained localized. Neo-liberalism, on the other hand, offers a cautionary tale about the limitations of international cooperation and the failure of economic interdependence to prevent war in an era of rising protectionism and imperial competition. The lack of robust, effective international institutions capable of addressing the causes of tension was a critical weakness of the global order.

From a Marxist perspective, the war can be seen as an expression of deeper economic and imperialist forces, where the capitalist competition for markets and resources drove imperial powers into conflict. The war also exposed the tensions between capitalist elites and the working classes, whose lives were ultimately sacrificed for the profit motives of the industrialists and bankers who stood to gain from the war. Meanwhile, constructivism emphasizes that the war was not merely the result of material forces but was also shaped by deeply held national identities, political ideologies, and the collective beliefs of political elites. The interaction of these ideologies, particularly nationalism and militarism, fueled the decisions that led to the outbreak of war.

Critical theories, such as postcolonialism and feminist theory, provide essential insights into how war was not just a clash of powers but also a manifestation of broader social, political, and economic inequalities. These theories question the very foundations of the international system and suggest that World War I was a result of the oppression and subjugation of weaker states, peoples, and marginalized groups, particularly in colonial territories. The war, in this view, was not just a conflict between great powers but a manifestation of global structural injustices, where the consequences were felt most acutely by those outside the centers of power.

Ultimately, the application of these theories to World War I serves as a reminder of the dangers of unchecked nationalism, militarism, and imperialism, as well as the vulnerabilities inherent in an anarchic international system where cooperation is often difficult and states prioritize security over collaboration. The war also underscores the importance of institutions, diplomacy, and economic ties in maintaining peace and preventing conflict. In the aftermath of World War I, the world sought to build a new international order through the establishment of the League of Nations, aiming to provide a forum for resolving disputes and fostering cooperation to prevent future wars. However, the failure of the League and the subsequent rise of totalitarian regimes in the interwar period demonstrated that the lessons of the war had not been fully learned.

The theories we apply to the causes of World War I are not merely academic exercises but offer valuable insights into the dynamics of power, security, and cooperation that continue to shape international relations today. Understanding the historical roots of conflict and the interplay of material and ideational factors is crucial for navigating contemporary global challenges, from the rise of new great power rivalries to the persistence of economic inequalities and the quest for dominance in the international system. In this sense, the study of World War I, through the lens of IR theories, offers both a cautionary tale and a vital framework for addressing the complex issues that continue to define global politics. It teaches us that while the world has changed in many ways since 1914, the fundamental dynamics of competition, cooperation, and conflict remain deeply relevant to the shaping of international relations in the present and future.
