The outbreak of the First World War in 1914 marked the culmination of decades of political, military, and economic tensions in Europe. While the assassination of Archduke Franz Ferdinand in Sarajevo on June 28, 1914, by Gavrilo Princip is often seen as the immediate trigger, the causes of the war were far more complex and had deep roots in the shifting alliances, rivalries, and national ambitions of the 19th and early 20th centuries. In the years leading up to the war, Europe was divided into competing power blocs, and imperial expansion, nationalism, and militarism played central roles in pushing the continent toward a catastrophic conflict. For Canada, the war not only represented a major turning point in its national development, but it also marked its emergence as an independent actor on the world stage.
The Rise of German Power and European Alliances
One of the key developments that set the stage for the war was the unification of Germany in 1871 under Otto von Bismarck, which fundamentally altered the balance of power in Europe. Prior to this, Germany had been a collection of small, competing states, but Bismarck's consolidation of these into a powerful empire expanded its influence and territorial reach. Germany’s newfound strength quickly became a source of anxiety for neighboring countries, especially France, which had been humiliated in the Franco-Prussian War (1870-1871). The defeat left France with a desire for revenge and the recovery of the lost provinces of Alsace and Lorraine, which only intensified the tensions in Europe.
Germany, under Bismarck’s leadership, sought to secure its position in Europe by forming a series of alliances. In 1879, Germany allied with Austria-Hungary through the Dual Alliance, with the aim of isolating France and preventing a potential two-front war. In 1882, Italy joined Germany and Austria-Hungary to form the Triple Alliance. This alliance system not only gave Germany a sense of security but also created an oppositional force that would later confront the emerging Triple Entente.
However, after Kaiser Wilhelm II ascended to the throne in 1888, he dismissed Bismarck in 1890 and pursued a more aggressive foreign policy. Kaiser Wilhelm’s ambitions for a global empire and his desire to build a powerful navy, which could rival that of Britain, created a new dynamic of competition. Germany’s growing strength, both militarily and economically, began to alarm other European powers, particularly France and Russia, which entered into a defensive alliance in 1894. This Franco-Russian Alliance was designed to counterbalance Germany’s power in Europe and marked the beginning of a deepening divide between rival alliances.
The Creation of the Triple Entente
Britain, traditionally averse to continental alliances and a proponent of a policy known as "splendid isolation," began to reassess its position in the early 20th century. German naval expansion under Admiral Alfred von Tirpitz and the construction of the Kiel Canal and the fortification of Heligoland as a naval base presented direct challenges to Britain’s naval supremacy and control of the North Sea. The Anglo-German naval arms race, which began in the early 1900s, further strained relations, as both nations invested heavily in Dreadnought-class battleships, raising the specter of conflict.
At the same time, Britain faced economic challenges, losing ground in industrial production to both Germany and the United States. Concerns over the Boer War (1899-1902) and the massacre of Christians in the Ottoman Empire also caused a shift in British foreign policy. By 1904, Britain had entered into the Entente Cordiale with France, resolving their colonial disputes in North Africa and Egypt and paving the way for further cooperation. In 1907, Britain concluded an agreement with Russia, completing the formation of the Triple Entente. By this point, Europe was now divided into two rival blocs: the Triple Alliance of Germany, Austria-Hungary, and Italy, and the Triple Entente of Britain, France, and Russia.
Tensions in the Balkans
While the European powers were drawn into rival alliance systems, tensions in the Balkans played a critical role in bringing about war. Both Austria-Hungary and Russia sought to expand their influence in this region, which had been left in flux following the decline of the Ottoman Empire. For Austria-Hungary, the Balkans represented a region where it could extend its control, while Russia saw itself as the protector of the Slavic peoples, especially Serbia, which had aspirations of unifying Slavic territories under its leadership.
The flashpoint came in Bosnia and Herzegovina, territories that Austria-Hungary formally annexed in 1908 after occupying them since the Congress of Berlin in 1878. This move infuriated Serbia, which had hoped to create a Slavic union, and further soured relations between Austria-Hungary and Russia, which supported Serbia’s ambitions. A series of crises followed, including the Balkan Wars of 1912-1913, which saw Serbia emerge as a powerful regional actor, further frustrating Austria-Hungary’s designs on the Balkans.
The Assassination in Sarajevo
Amid these tensions, Archduke Franz Ferdinand, heir to the Austro-Hungarian throne, was assassinated in Sarajevo by Gavrilo Princip, a Bosnian Serb nationalist, on June 28, 1914. Princip was a member of Young Bosnia, a revolutionary organization seeking to end Austro-Hungarian rule over Bosnia and create a Greater Serbia. The assassination was the spark that ignited the powder keg of Europe, as Austria-Hungary saw the event as an opportunity to crush Serbia and reassert its dominance in the Balkans.
Austria-Hungary, with Germany’s backing, issued an ultimatum to Serbia, demanding a series of measures that would effectively allow Austria-Hungary to control Serbian affairs. Serbia’s response, though conciliatory in many respects, did not meet all of Austria-Hungary’s demands, leading to the declaration of war on July 28, 1914. This localized conflict quickly escalated as the complex web of alliances came into play. Russia, as Serbia’s protector, began to mobilize its forces, prompting Germany to declare war on Russia on August 1, and on France two days later. Germany’s Schlieffen Plan, which involved invading France through neutral Belgium, brought Britain into the war on August 4.
The Road to Total War
The various alliances, ambitions, and rivalries that had been simmering for decades finally erupted into a full-scale conflict. What was initially expected to be a brief war soon devolved into a stalemate of trench warfare that would claim millions of lives and devastate Europe. Germany’s Schlieffen Plan failed to deliver a quick victory, and the war of attrition that followed would stretch on for four years, drawing in nations from across the globe.
The Impact on Canada
For Canada, the First World War represented a crucial moment in its national development. At the time, Canada was still seen as a dominion of the British Empire, but its participation in the war helped solidify its status as an emerging independent nation. Initially, Prime Minister Robert Borden had pledged 25,000 men to the war effort, but by 1916, Canada had committed to sending 500,000, a remarkable contribution for a country of just over seven million people. The Canadian Expeditionary Force would go on to distinguish itself in battles such as Vimy Ridge and the Somme, earning Canada recognition as a formidable military force.
The war also transformed Canadian society. It accelerated the shift from a rural to an urban economy, spurred industrial growth, and set the stage for increased political autonomy. Canada’s participation in the war effort led to a greater sense of national identity, as soldiers from across the country fought and died together on the battlefields of Europe. By the war’s end, Canada had not only proven its loyalty to the Empire but had also earned the right to sign the Treaty of Versailles independently, marking a significant step toward full sovereignty.
The First World War was the result of a complex web of alliances, rivalries, and ambitions that had been building for decades. The rise of Germany, the division of Europe into two competing blocs, the arms race between Britain and Germany, and the tensions in the Balkans all played critical roles in setting the stage for the conflict. While the assassination of Archduke Franz Ferdinand was the immediate trigger, the deeper causes of the war lay in the political, military, and economic transformations that had been reshaping Europe since the 19th century.
For Canada, the war marked a pivotal moment in its history. It was a time when the young nation came of age, demonstrating its military and political capabilities on the world stage. The war would have profound and lasting impacts on Canadian society, economy, and politics, shaping the country’s identity for decades to come.
