21.13.3 Causes of the First World War (1914-1918)

The onset of the First World War in 1914 marked a catastrophic turn in European and global history. This detailed exploration examines the intricate web of factors that culminated in the war, shedding light on both immediate and deep-seated causes.

Short-Term and Long-Term Causes

Immediate Catalyst: The July Crisis of 1914

  • Assassination of Archduke Franz Ferdinand: The assassination on 28 June 1914 of Franz Ferdinand, heir to the Austro-Hungarian throne, by Gavrilo Princip, a Bosnian Serb nationalist, in Sarajevo, was a critical trigger. This event caused shockwaves throughout Europe, particularly in Austria-Hungary.
  • Austro-Hungarian Ultimatum to Serbia: Austria-Hungary's response was a stern ultimatum to Serbia, which included demands that infringed on Serbian sovereignty. Serbia's partial compliance was deemed insufficient, leading to Austria-Hungary's declaration of war on 28 July 1914.
  • Mobilisation of Forces: The refusal of the ultimatum led to a rapid mobilisation of forces across Europe. Russia mobilised in support of Serbia, prompting German mobilisation and subsequent declarations of war.

Underlying Factors

  • Nationalism: Nationalist fervour, particularly in the Balkans, contributed to an atmosphere of competition and mistrust among European nations. Ethnic groups sought self-determination and independence, challenging existing imperial and national boundaries.
  • Imperial Rivalries: The quest for colonial possessions created deep-seated rivalries among European powers, particularly between Britain and Germany, and France and Germany. These rivalries extended beyond Europe, affecting global politics.
  • Economic Competition: The rise of Germany as an industrial and economic power threatened established powers like Britain and France, leading to economic competition that paralleled military rivalries.
  • Militarism: An escalation in military spending and advancements in weaponry among European powers, notably the Anglo-German naval arms race, created a sense of inevitability regarding war.

The Alliance System

  • Triple Entente: The alliance of France, Russia, and Britain, formed in response to the growing power of Germany, was a key element in the European balance of power. This alliance was not a formal treaty but a series of agreements that solidified mutual support.
  • Triple Alliance: Germany, Austria-Hungary, and Italy's alliance was designed to provide mutual support and counterbalance the Triple Entente. Italy’s later defection to the Entente was a significant shift in the alliance dynamics.
  • Entangling Alliances: The complex network of alliances meant that a conflict between two powers could quickly involve their respective allies, turning a localised conflict into a world war.

Decline of the Ottoman Empire

  • "Sick Man of Europe": The gradual decline of the Ottoman Empire, often referred to as the "Sick Man of Europe", created a power vacuum, especially in the Balkans, a region of strategic importance and ethnic complexity.
  • Balkan Wars: The two Balkan Wars, which redrew the map of southeastern Europe, were symptomatic of the instability and nationalist aspirations in the region. These wars increased tensions among the Great Powers, who had vested interests in the region.

German Foreign Policy

  • Weltpolitik: Kaiser Wilhelm II’s adoption of 'Weltpolitik' aimed to establish Germany as a dominant world power. This policy involved aggressive diplomacy, military buildup, and a challenge to British naval supremacy.
  • Naval Expansion: Germany’s decision to build a fleet capable of challenging the British Royal Navy was seen as a direct threat by Britain, leading to increased naval expenditure and heightened tensions between the two countries.

Austria-Hungary and Russia

  • Austrian Concerns: The multinational empire of Austria-Hungary faced internal divisions and rising nationalism among its Slavic population, particularly Serbs, who were inspired by Serbian nationalism.
  • Russian Ambitions: Russia, considering itself the protector of Slavic peoples, was deeply involved in Balkan politics. Russian support for Serbia was in direct opposition to Austro-Hungarian interests, setting the stage for conflict in the region.

Balkan Nationalism

  • Rise of Nation-States: The emergence of nation-states in the Balkans, such as Serbia, Bulgaria, and Greece, following the decline of the Ottoman Empire, introduced new dynamics into European politics.
  • Serbian Nationalism: Serbian nationalism was a significant factor in regional tensions. Serbia's ambition to unite all South Slavs, including those under Austro-Hungarian rule, was a direct threat to the integrity of the Habsburg Empire.

The Arms Race

  • Technological Advancements: The late 19th and early 20th centuries saw significant advancements in military technology, including more effective firearms, artillery, and the advent of warplanes and tanks. These advancements spurred an arms race among the European powers.
  • Mobilisation Plans: Countries like Germany and Russia developed detailed mobilisation plans. The German Schlieffen Plan, for example, was a strategy for a two-front war against France and Russia, which necessitated rapid mobilisation and aggressive action.

Diplomatic Crises

  • Moroccan Crises: The First (1905) and Second (1911) Moroccan Crises were international crises over the status of Morocco. Germany's attempts to challenge French influence in Morocco failed but exacerbated tensions with both France and Britain.
  • Bosnian Crisis (1908): Austria-Hungary’s annexation of Bosnia and Herzegovina provoked Serbia and Russia, creating a hostile atmosphere in the Balkans. This crisis was a clear demonstration of the fragility of peace and the combustible nature of Balkan nationalism.

In sum, the First World War was the culmination of a series of interconnected causes. From the immediate spark in the July Crisis of 1914 to deeper issues like nationalism, imperial rivalry, and the complex alliance system, these factors collectively set the stage for one of the most devastating conflicts in human history. Understanding these causes is essential for comprehending the broader narrative of early 20th-century history.

FAQ

The Moroccan Crises of 1905 and 1911 were significant in exacerbating tensions between the European powers, contributing to the build-up to the First World War. The First Moroccan Crisis (1905) arose when Germany challenged France's influence in Morocco, seeking to undermine the Anglo-French Entente and test the strength of their alliance. This crisis heightened tensions between Germany and France and brought Britain closer to France, reinforcing the Entente Cordiale. The Second Moroccan Crisis (1911), involving a German gunboat sent to Agadir, further strained relations, particularly between Germany and Britain, over colonial ambitions in Africa. These crises not only intensified rivalry and mistrust among the major powers but also demonstrated the fragility of the existing diplomatic balance, contributing to the growing atmosphere of hostility and suspicion in pre-war Europe.

The arms race and advancements in military technology were significant factors in the outbreak of the First World War. The late 19th and early 20th centuries saw rapid developments in military technology, including more effective firearms, artillery, and the emergence of new technologies such as airplanes and tanks. These advancements spurred a competitive arms race among the European powers. Countries like Germany, Britain, France, and Russia invested heavily in building up their military capabilities, both in terms of quantity and technological sophistication. This arms race created a sense of inevitability and readiness for war, as nations not only increased their military capabilities but also developed more aggressive military doctrines and plans. The belief that war was imminent and winnable with the new technologies contributed to a willingness to resort to military solutions, escalating tensions and making diplomatic resolutions more challenging.

The Bosnian Crisis of 1908 significantly impacted the relationships among the European powers, particularly between Austria-Hungary, Russia, and Serbia, and contributed to the tensions leading to the First World War. The crisis was triggered by Austria-Hungary's annexation of Bosnia and Herzegovina, territories with significant Slavic populations. This move angered Serbia and Russia, both of which had interests in the region. Serbia, backed by Russia, opposed the annexation due to its own territorial ambitions and the presence of ethnic Serbs in Bosnia. Russia, however, was forced to back down in the face of German support for Austria-Hungary, leading to a sense of humiliation and resentment. This crisis not only heightened tensions in the Balkans but also strained Austro-Russian relations. It also contributed to the development of the Serbian nationalism that would later play a key role in the assassination of Archduke Franz Ferdinand, sparking the war.

Economic competition, especially between Britain and Germany, significantly contributed to the build-up to the First World War. By the early 20th century, Germany had emerged as a major industrial power, challenging Britain's economic supremacy. This rivalry extended beyond mere commercial competition; it was intertwined with military and naval power. Germany's rapid industrial growth fuelled its ambitions for a global empire and necessitated a strong navy, leading to the Anglo-German naval arms race. This competition for naval supremacy was emblematic of the broader economic rivalry. Additionally, economic interests influenced colonial ambitions, with both nations seeking to expand their empires, further straining relations. Thus, economic competition was not only a source of tension but also a factor that intertwined with and amplified other issues, such as militarism and imperialism, contributing to the war's onset.

The decline of the Ottoman Empire, often termed as the "Sick Man of Europe", had significant implications for European diplomatic relations, contributing indirectly to the First World War. As the Ottoman Empire weakened, it created a power vacuum in the Balkans and Eastern Europe, leading to intensified competition among the Great Powers. Russia, Austria-Hungary, and others sought to extend their influence in these regions. This scramble for territory and influence exacerbated existing tensions, particularly in the Balkans where nationalist movements were gaining momentum. The strategic importance of the Ottoman territories, including control of sea routes and access to resources, heightened the stakes, making diplomatic relations more competitive and tense. The empire's gradual disintegration thus added another layer of complexity to the already volatile European political landscape, indirectly setting the stage for the outbreak of the war.

Practice Questions

Evaluate the significance of the alliance system in contributing to the outbreak of the First World War.

The alliance system played a critical role in the outbreak of the First World War by creating a rigid structure of mutual defence obligations among European powers. The Triple Entente (comprising France, Russia, and Britain) and the Triple Alliance (between Germany, Austria-Hungary, and Italy) polarised Europe into competing camps. This division transformed regional disputes into global conflicts, as seen in the July Crisis of 1914 following the assassination of Archduke Franz Ferdinand. The intricate web of alliances meant that a declaration of war by one country rapidly involved its allies, turning a Balkan crisis into a world war. The system created a domino effect, where tensions escalated beyond control, significantly contributing to the war’s outbreak.

Discuss how nationalism in the Balkans contributed to the start of the First World War.

Nationalism in the Balkans was a major factor in the lead-up to the First World War. The region, known as the "powder keg of Europe", was characterised by intense nationalist sentiments among various ethnic groups seeking independence or territorial expansion. Serbian nationalism, in particular, played a pivotal role, as Serbia's desire to unite South Slavic peoples threatened the stability of the Austro-Hungarian Empire. The assassination of Archduke Franz Ferdinand by a Serbian nationalist was both a product and symbol of this volatile nationalism. The event triggered a series of actions leading to war, showcasing how Balkan nationalism was a significant catalyst in the conflict’s genesis.
