Causes of World War I and U.S. Neutrality Efforts
This paper examines the major causes of World War I, tracing the web of mutual defense alliances — including the Triple Alliance and the Triple Entente — that bound European powers into conflict. It discusses how imperialism, militarism, and nationalist tensions, particularly in the Balkans, created conditions ripe for war. The paper also details the assassination of Archduke Franz Ferdinand as the immediate trigger and traces the rapid chain of events that followed. A second focus covers the United States' initial neutrality under President Woodrow Wilson, the factors that eroded that neutrality, and Wilson's Fourteen Points as a framework for postwar peace.

What makes this paper effective
- Provides a clear, structured survey of multiple interrelated causes — alliances, imperialism, militarism, and nationalism — before moving to the triggering event, giving readers a layered understanding of the war's origins.
- Transitions logically from the European context to the American response, demonstrating how the war's causes shaped later U.S. foreign policy decisions.
- Uses concrete historical examples (the Morocco crises, the Zimmermann Telegram, the sinking of the Lusitania) to support each analytical point.
Key academic technique demonstrated
The paper demonstrates causal chaining — showing how each factor (alliances, imperialism, nationalism, a single assassination) connected to and amplified the others until war became inevitable. Rather than treating causes as isolated points, the author links them sequentially, making the argument cumulative and more persuasive.
Structure breakdown
The paper opens with the pre-war alliance system, then broadens to structural causes (imperialism, militarism, nationalism), narrows to the specific triggering event (the Franz Ferdinand assassination), and finally shifts perspective to U.S. neutrality and Wilson's peace framework. This funnel-then-expand structure moves from macro forces to a single catalytic moment and then outward again to international response.
European Alliance Systems Before World War I
Nations all over Europe formed mutual defense treaties that would draw them into war with one another. These agreements stipulated that if one nation were invaded, its allied nations were obligated to defend it. The following alliances existed prior to World War I:
- Japan and Britain
- Russia and Serbia
- France and Russia
- Germany and Austria-Hungary
- Britain, France, and Belgium
The Triple Alliance was created in 1882 by Germany, Italy, and Austria-Hungary. These three nations agreed to support one another in the event of an attack from either Russia or France. France, in particular, felt threatened by this alliance. The main aim of the alliance was to foster collaboration against what Germany perceived as a mutual threat. Three years later, Russia — alarmed by the growth of the German Army — united with France and Britain to form the Triple Entente. Unlike the Triple Alliance, the terms of the Entente did not require each nation to go to war on behalf of the others; however, the member states held a "moral obligation" to support one another. The Russian government was also concerned about Austria-Hungary's ambitions to expand its empire, and consequently pledged to assist Serbia in the event of an attack by members of the Triple Alliance.
Imperialism, Militarism, and the Arms Race
Imperialism refers to the process by which a nation expands its wealth and power by bringing additional territories under its control. Prior to World War I, Africa and various regions of Asia were flashpoints of competition among European nations, owing in particular to the raw materials those regions could supply. Rising competition and the desire for larger empires increased international confrontation and helped push the world toward war.
An arms race was already underway as the world entered the 20th century. By 1914, Germany had experienced the greatest military expansion of any nation. Both Germany and Britain significantly enlarged their naval fleets during this period. Moreover, particularly in Germany and Russia, the military establishment began to exert considerable influence over public policy. This growth in militarism helped push nations further toward armed conflict.
Nationalism and the Balkan Crisis
Much of the war's origin was rooted in the desire of Slavic peoples in Bosnia and Herzegovina to break away from Austria-Hungary and unite with Serbia. In this specific sense, nationalism directly contributed to the outbreak of war. More broadly, the nationalist ambitions of various nations across Europe played a role in both the initiation and the prolongation of the conflict, as each nation sought to demonstrate its power and supremacy.
In 1904, Britain ceded Morocco to France; however, the Moroccan people sought independence. In 1905, Germany declared its support for Moroccan independence, and war was narrowly avoided through a diplomatic conference that allowed France to retain control of Morocco. In 1911, Germany again challenged French ownership of Morocco. Britain backed France, and Germany was persuaded to accept a portion of the French Congo as compensation. In 1908, Austria-Hungary annexed Bosnia, the former Turkish province, angering Serbia, which believed the territory should belong to it. Serbia threatened Austria-Hungary with war; Russia, allied with Serbia, mobilized its forces. Germany, allied with Austria-Hungary, responded by mobilizing its own forces and threatening Russia. Russia's decision to back down prevented war at that moment. Nevertheless, conflict erupted in the Balkans between 1911 and 1912, when the Balkan states expelled Turkey from the region and subsequently fought among themselves over the division of that territory. Serbia was compelled to relinquish some of its gains after Austria-Hungary intervened, leaving tensions between Austria-Hungary and Serbia extremely high.
The Assassination of Archduke Franz Ferdinand
In 1914, Archduke Franz Ferdinand, heir to the Austro-Hungarian Empire and nephew of Emperor Franz Josef, was shot and killed — along with his wife — by a Serbian-Bosnian nationalist in an event widely recognized as the immediate trigger of World War I. Otto von Bismarck, the renowned Prussian statesman credited with German unification in 1871, had predicted near the end of his life that a great European war would one day result from "some damned stupid thing in the Balkans." Events unfolded precisely as he had foreseen.
The assassination of Franz Ferdinand and his wife Sophie set off a rapid chain of events. Austria-Hungary held the Serbian government responsible for the attack and sought to use the incident as a pretext for settling the question of Slavic nationalism once and for all. While Russia signaled its support for Serbia, Austria-Hungary delayed its declaration of war until its leaders received assurances from Kaiser Wilhelm II that Germany would back them in the event of Russian intervention. Austria-Hungary declared war on Serbia on July 28, and the fragile peace among Europe's great powers collapsed. Within a week, Russia, France, Belgium, Serbia, and Great Britain had aligned against Germany and Austria-Hungary — and World War I had begun.
