Materials & Prep
Prepare a projected image or brief statement about the Titanic sinking, a four-column cause organizer labeled militarism, alliances, nationalism and imperialism, and a source packet containing: the Treaty of the Triple Alliance, 1882, Articles 1–2; the German Naval Law, 1898; the Anglo-Russian Convention, 1907, sections on Persia; the Austro-Hungarian ultimatum to Serbia, 23 July 1914; and the Serbian reply, 25 July 1914. Students should have paper or a notebook. Confirm local procedures for distributing and handling source copies.
Opening
Display“The Titanic sank because it hit an iceberg.” Ask students to decide whether this is a complete explanation. In pairs, students list two other conditions that helped turn the collision into a disaster, such as the ship’s speed, the number of lifeboats or the response after the collision. They can use ordinary knowledge and do not need historical vocabulary.
DiscussInvite two pairs to share. Emphasize that the iceberg was the immediate trigger, but a strong explanation also identifies conditions that made the disaster possible or worse. Connect: “The assassination of Archduke Franz Ferdinand was an immediate trigger for war. Today we will test whether it explains the war by itself, or whether other conditions made a general European war likely.”
Direct instruction
ExplainBuild the four-column organizer. Militarism means competition to build armed forces and plan for war. Alliances are commitments that can turn a regional conflict into a wider one. Nationalism encouraged loyalty to nations or ethnic groups and intensified Serbian and Austro-Hungarian conflict. Imperialism increased rivalry among European powers, although it was less direct in July 1914 than the other causes.
Think aloudModel the difference between a trigger and a deeper cause. “The assassination occurred on 28 June 1914, so it clearly triggered the crisis. But an assassination does not automatically produce a world war. I ask what conditions connected Austria-Hungary, Serbia, Russia, Germany, France and Britain. Alliance commitments, military planning and nationalist conflict help explain that connection.”
ConfrontWrite “World War I began because Gavrilo Princip assassinated Franz Ferdinand” on the board. Ask students to mark it complete or incomplete and justify their choice. Correct the misconception directly: the assassination explains why the July Crisis began, not why the crisis escalated into a general war. Introduce the sequence: long-term conditions, immediate crisis, escalation and mobilization.
Check for understandingStudents hold up one finger for “long-term condition,” two for “immediate trigger,” and three for “escalation” as you name: the arms race, the assassination, Austria-Hungary’s ultimatum, and alliance commitments. Ask one student to explain why the assassination receives a two rather than a one.
Guided practice
Have students work in groups of three. Give each group the five identified sources. Students annotate each source with its author or issuing government, date, purpose and the cause or stage of the crisis it best reveals. They should use the source itself, not simply the document title, as evidence.
PromptFor the Treaty of the Triple Alliance, 1882, look at the mutual-support provisions and ask what would happen if one member entered a conflict. For the German Naval Law, 1898, identify evidence of military competition. For the Anglo-Russian Convention, 1907, examine how European powers settled imperial disputes while remaining organized in rival diplomatic groupings. For the Austro-Hungarian ultimatum and Serbian reply, compare the demands, the response and the possibility of peaceful resolution.
CirculateRequire each group to complete the sentence, “This source makes war more likely because…” Support students with the organizer and the sentence frame “The document’s purpose and wording suggest that viewed as a threat.” Extension: Ask ready students to identify a limitation in one source, such as government perspective, intended audience or the gap between a formal agreement and actual behavior.
Independent discussion
WriteStudents answer the following prompt in one developed paragraph or a structured claim-evidence-reasoning response: “Why did the First World War begin? Rank the two most important causes and explain why the assassination alone is not a sufficient explanation.” Students must use at least three pieces of evidence, including one from a source, and distinguish the immediate trigger from underlying causes.
ScaffoldProvide this frame for students who need it: “Although the assassination of Franz Ferdinand triggered the July Crisis, the war became general because and . Evidence from shows . This mattered more than because .” Students may first sort evidence into the four-column organizer before writing. Stronger students should address a counterargument, such as “The assassination was the most important cause because without it war might not have begun in 1914,” and then explain whether that makes it the deepest cause or only the immediate trigger.
DiscussInvite two students with different rankings to read their claims. Ask, “Which evidence best supports the ranking, and what evidence might another historian use to challenge it?”
Closing
Exit ticketIn three to five sentences, answer: “Was the assassination of Franz Ferdinand the cause of the First World War, the trigger of the war, or both? Explain your answer using two other causes and one specific piece of evidence.” Require students to name at least one long-term condition and explain how it helped turn a regional crisis into a wider war.
