Causes of World War One and America's Entry Into the War

~5 min read 5 sections History · First World War
Abstract

This essay examines the causes of World War One and the circumstances surrounding America's entry into the conflict. Drawing on Barbara Tuchman's The Guns of August and Walter Karp's The Politics of War, the paper traces the collapse of aging European empires, ethnic nationalism, a web of secret alliances, and nineteenth-century imperialism as the structural roots of the war. It then analyzes Woodrow Wilson's decision to bring the United States into the conflict, weighing the Zimmerman telegram, German submarine warfare, and Wilson's personal ambitions against the backdrop of America's growing global aspirations. The paper closes by contrasting Tuchman's and Karp's interpretations of Wilson's motivations.

Key Takeaways
  • The Scale and Immediate Causes of World War One: Casualties, failing empires, and war's outbreak
  • Ethnic Nationalism and the Powder Keg of Europe: Ethnic unrest and Franz Ferdinand's assassination
  • Nineteenth-Century Imperialism and the Scramble for Territory: Imperial competition and German expansion in Europe
  • America's Delayed Entry and Wilson's Motivations: Wilson's neutrality, Zimmermann telegram, and global ambitions
  • Tuchman and Karp on Wilson's Purposes: Competing historical views on Wilson's true motives

What makes this paper effective

  • The opening statistics about casualties at the Somme and Verdun immediately establish the war's staggering human cost, grounding the analysis in concrete evidence before moving to causation.
  • The paper skillfully weaves together two scholarly sources — Tuchman and Karp — using them not just as supporting evidence but as competing interpretive frameworks, particularly in the final section on Wilson's motivations.
  • The essay moves logically from broad structural causes (imperial decline, ethnic nationalism) to specific triggering events (the assassination, the Zimmermann telegram), demonstrating multilevel historical analysis.

Key academic technique demonstrated

The paper demonstrates source synthesis and comparative historiography. Rather than simply citing Tuchman and Karp in agreement, the writer explicitly identifies where the two historians diverge — on Wilson's character and ultimate purposes — and uses a direct quotation from Karp to give that divergence analytical weight. This technique of setting sources in dialogue with one another elevates the essay beyond summary.

Structure breakdown

The essay opens with casualty statistics to establish stakes, then moves through the political collapse of aging European empires, ethnic separatism as an accelerant, global imperialism as structural context, and finally America's entry into the war. The conclusion narrows to a pointed historiographical debate between the two primary sources, giving the essay a clear argumentative arc from macro-causes to individual agency.

The Scale and Immediate Causes of World War One

World War One ultimately killed 35 million people — this alone might have merited its being called "The Great War," although to a large degree it was the astonishing way in which the deaths happened. On the first day of the Battle of the Somme alone, Britain suffered almost sixty thousand casualties. The ten-month stalemate of the Battle of Verdun resulted in 700,000 dead, with no discernible tactical advance made by either side (Tuchman 174).

The immediate causes of World War One were complicated but fairly straightforward. Many of the long-standing political institutions of Europe were badly outmoded, in particular two of the oldest: the Austro-Hungarian Empire and the Ottoman Empire. Each was the inheritor of a previous large-scale imperial institution — the Holy Roman Empire and the Byzantine Empire, respectively — dating back nearly a thousand years, and each was failing badly. By the time war broke out, for example, the Ottoman Empire had for decades been referred to as "the sick man of Europe," owing to its territorial losses in various smaller conflicts, its failing infrastructure, and its growing financial indebtedness to the larger European powers (Tuchman 141).
