The Great War is the original name for World War I (1914-1918), a global conflict between the Allies and the Central Powers caused by imperialist competition, intense nationalism, territorial disputes, and a flawed alliance system, tested in AP World Topic 7.2.
The Great War is what people called World War I before there was a second one. It ran from 1914 to 1918 and pulled in most of the world's great powers, split into the Allied Powers and the Central Powers. If you see "the Great War" in a document on the exam, it's a primary-source clue that the writer is talking about WWI from inside that moment, when nobody knew a bigger war was coming.
The AP World CED (Topic 7.2) cares less about battles and more about why this war happened. The essential knowledge spells out the causes directly. Imperialist expansion and competition for resources made the great powers rivals. Territorial and regional conflicts (especially in the Balkans) created flashpoints. A flawed alliance system meant one local crisis dragged everyone in. And intense nationalism made compromise feel like betrayal. Add militarism, and you get the famous MAIN mnemonic (Militarism, Alliances, Imperialism, Nationalism). The assassination of Archduke Franz Ferdinand was the spark, but the CED wants you to see it as the trigger of deeper, long-building tensions, not the cause itself.
The Great War anchors Topic 7.2 (Causes of World War I) in Unit 7: Global Conflict, 1900-Present, and supports learning objective AP World 7.2.A, which asks you to explain both the causes and consequences of World War I. It's also the hinge of the whole unit. The war's consequences (collapsed empires, the Treaty of Versailles, mass mobilization of colonial troops and home fronts) set up nearly everything that follows in Units 7 and 8, from the rise of fascism to decolonization movements demanding payback for wartime service. If you can explain why the Great War broke out and what it broke, you've got the causation skill the exam loves to test.

Alliance System (Unit 7)
This is the closest linked concept. The CED literally calls the alliance system "flawed" because it turned a regional Balkan crisis into a world war. Think of it as a chain of dominoes where knocking over Serbia eventually knocked over Britain.
Imperialism (Unit 6)
The Great War is where Unit 6 cashes out. Decades of imperialist competition for colonies and resources made the European powers rivals long before 1914, which is why the exam loves cross-unit causation questions linking imperialism to WWI.
Nationalism (Units 5-7)
Nationalism unified Germany and Italy in the 1800s, but by 1914 it was tearing multiethnic empires apart. Serbian nationalism (acting through the Black Hand) produced the assassination that lit the fuse.
Franz Ferdinand (Unit 7)
His assassination in June 1914 is the classic "proximate cause" of the Great War. The skill move on the exam is distinguishing this spark from the underlying MAIN causes that made the explosion possible.
Multiple-choice questions often use a primary source that says "the Great War," and you're expected to recognize it as WWI immediately. Fiveable practice questions also test the MAIN mnemonic directly, asking you to match Militarism, Alliances, Imperialism, and Nationalism to the war's underlying causes. For free-response writing, this term lives in causation territory. No released FRQ has used "the Great War" verbatim, but LO 7.2.A (explain the causes and consequences of World War I) is exactly the kind of prompt LEQs and SAQs are built on. The strongest answers separate long-term causes (imperialist rivalry, nationalism, the alliance system) from the immediate trigger (Franz Ferdinand's assassination), then trace consequences forward into the rest of Unit 7.
The Great War is World War I (1914-1918), not World War II. People called it "the Great War" or even "the war to end all wars" because nothing that destructive had ever happened, and they assumed nothing like it would happen again. Once WWII broke out in 1939, the name shifted to "World War I." On the exam, a source dated before 1939 that mentions "the Great War" is always talking about WWI.
The Great War is the original name for World War I, fought from 1914 to 1918 between the Allied Powers and the Central Powers.
The CED identifies its causes as imperialist expansion and resource competition, territorial and regional conflicts, a flawed alliance system, and intense nationalism, which the MAIN mnemonic helps you remember.
The assassination of Franz Ferdinand was the trigger, not the underlying cause, and strong AP answers keep that distinction clear.
The alliance system is what turned a regional Balkan conflict into a global war, which is why the CED calls it flawed.
When a primary source says "the Great War," it was written before World War II existed, so it always means WWI.
The war's consequences, including collapsed empires and the Treaty of Versailles, set up the conflicts you'll study in the rest of Unit 7.
The Great War is World War I, the 1914-1918 global conflict between the Allies and the Central Powers. AP World tests it in Topic 7.2, focusing on its causes (imperialism, nationalism, alliances, militarism) and consequences.
Yes, they're the exact same war. "The Great War" is just what people called WWI before World War II existed, so the name only signals when a source was written, not a different conflict.
The CED lists imperialist expansion and competition for resources, territorial and regional conflicts, a flawed alliance system, and intense nationalism. The MAIN mnemonic (Militarism, Alliances, Imperialism, Nationalism) shows up in practice questions for exactly this reason.
The Great War is WWI (1914-1918), fought between the Allies and Central Powers and sparked by Franz Ferdinand's assassination. World War II came two decades later, and its name only exists because the "war to end all wars" turned out not to be.
Not by itself. The assassination in June 1914 was the trigger, but the CED makes clear the real causes were long-term tensions from imperialism, nationalism, territorial conflicts, and the alliance system. Causation FRQs reward you for making that distinction.
