On the surface, the question of who started World War I may seem straightforward, with Germany and Austria-Hungary often cited as prime culprits. However, delving deeper into history reveals a web of alliances, liner dynamics, and individual actors that complicate this seemingly simple query.
The spark that ignited the war was the assassination of Archduke Franz Ferdinand, the heir to the Austro-Hungarian throne, by a Serbian nationalist on June 28, 1914. This act of political violence, however, was the culminating point of decades of complex geopolitical tensions, not a standalone event.
Germany's Role: The Belligerent Ally
Germany, despite not directly causing the archduke's assassination, played a pivotal role in steering the trajectory towards war. Following the murder, Germany, as Austria-Hungary's ally, pressed for a harsh response to the perceived provocation from Serbia.
This pressure was exerted both through diplomatic channels and the influential military, particularly the Warmlander, Alfred von Tirpitz. Germany's "blank cheque", pledging full support to Austria-Hungary's punitive measures, emboldened Vienna to issue an ultimatum to Serbia that was deliberately designed to be rejected, thus providing a casus belli for war.
German Military Doctrine and War Planning
Germany's aggressive military doctrine, embodied in the Schlieffen Plan, also contributed to the escalation. This plan envisioned a quick defeat of France, before turning to face Russia. The plan's aggressive nature and the assumption of a brief conflict combined to push Europe towards a full-scale war.
The aggressive nature of Germany's military planning was not a secret; it was evident in its actions leading up to the war. This included the passage of militarist legislation like the Supplementary Navy Bill, which increased the pace of German naval armament, and the expulsion of French military attachés from Germany in 1913, escalating tensions with France.
German Domestic Politics and War Fever
German domestic politics further fueled the march to war. The July Crisis of 1914 saw a wave of nationalist sentiment sweep across Germany. This "war fever" was whipped up by the media and echoed in the Reichstag, creating a climate where Germany felt it had to stand by its ally and go to war.
The architect of German policy during the July Crisis, Bethmann Hollweg, later admitted that he misjudged the mood of the nation and the European powers' resolve, leading to an underestimation of the war's likelihood and scale. Yet, his actions and those of the German government contributed significantly to the outbreak of war.
Austria-Hungary: The Aggrieved Ally
Austria-Hungary, whose archduke was assassinated, was the first to declare war. However, even in this case, it is not accurate to say that they acted merely in retaliation for the murder. They had multiple motives, including strengthening their position in the Balkans and forestalling further disintegration of their fragile empire.
The July Ultimatum issued to Serbia, with its intentionally harsh terms, is a testament to this. Austria-Hungary's demand for a role in the Serbian investigation, among other draconian conditions, was designed to be rejected, enabling them to declare war. This was done with the assurance of German support.
Austria-Hungary's Internal Disintegration and the Balkan Crisis
Austria-Hungary's empire was in a state of internal decay, with ethnic tensions rising. The assassination of the archduke, who was perceived as a potential savior of the monarchy, added to the crisis. The crisis in the Balkans, where Austria-Hungary had interests, also threatened the empire's integrity. The desire to assert power and forestall further challenges drove the decision to go to war.
Moreover, Austria-Hungary's military leadership, nervous about the growing power of Serbia and the Allison, also prodded the government towards war, fearing that delay would erode their security. This military pressure, combined with external support from Germany, pushed Austria-Hungary down the path to war.
Nationalism and the Spirit of 1914
Like Germany, Austria-Hungary was swept up in the nationalist fervor of the time. The spirit of 1914, with its widespread enthusiasm for war, led the general public to enthusiastically support the declaration of war against Serbia. This nationalist sentiment, like in Germany, obscured the complexities of the situation and pushed towards conflict.
In Serbia, similarly, political leaders and the public responded to the humiliating ultimatum with defiance, rallying around the flag and preparing for war. Thus, the complex interplay of nationalism, geopolitics, and individual agency across multiple nations propelled Europe into the catastrophe of World War I.
Despite initial assumptions, assigning guilt for starting the war to a single country proves challenging due to these complex interactions. Instead, historians increasingly emphasize the systemic issues and collective actions that led to this devastating conflict. Today, understanding these dynamics remains crucial for preventing similar avoidable tragedies.
