4.1 World War I & the Russian Revolution
Key Takeaways
- The long-term causes of World War I are remembered with the acronym MAIN: Militarism, Alliances, Imperialism, and Nationalism.
- The assassination of Archduke Franz Ferdinand in Sarajevo on June 28, 1914, was the short-term trigger that activated Europe's alliance system.
- New technology (machine guns, poison gas, tanks, submarines) made WWI a total war fought from trenches, producing roughly 9 million military deaths.
- The Treaty of Versailles (1919) blamed Germany through the War Guilt Clause, imposed reparations, and created the League of Nations.
- The Russian Revolution of 1917 brought Lenin and the Bolsheviks to power, withdrawing Russia from the war and founding the world's first communist state.
Why This Unit Matters for Global II
Framework unit 10.5 (Unresolved Global Conflict, 1914-1945) is one of the most heavily tested topics on the Regents, supplying anywhere from 1 to 9 Part I multiple-choice items and frequently appearing in constructed-response and enduring issues prompts. World War I is the gateway to the entire 20th century: it destroyed empires, redrew borders, and produced grievances that helped cause World War II. On the exam you will be asked to separate long-term causes from the immediate trigger and to identify the effects of the war, so organizing your thinking around cause and effect is essential.
Long-Term Causes: M-A-I-N
Historians group the underlying causes of the war into four categories. The acronym MAIN is the fastest way to recall them.
| Cause | Definition | Example |
|---|---|---|
| Militarism | Glorifying military power and building large armies/navies | Anglo-German naval arms race over battleships (dreadnoughts) |
| Alliances | Secret defensive pacts that pulled nations into one another's conflicts | Triple Alliance (Germany, Austria-Hungary, Italy) vs. Triple Entente (France, Russia, Britain) |
| Imperialism | Competition for colonies, resources, and markets | Rivalry over African and Asian territory |
| Nationalism | Intense pride and competition between nations; ethnic groups seeking self-rule | Slavic nationalism in the Balkans, the "powder keg of Europe" |
The Balkans were especially unstable because Slavic nationalists wanted independence from Austria-Hungary, and this is where the spark came.
The Trigger: Sarajevo, 1914
On June 28, 1914, Archduke Franz Ferdinand, heir to the Austro-Hungarian throne, was assassinated in Sarajevo by Gavrilo Princip, a Bosnian Serb nationalist linked to the Black Hand. Austria-Hungary blamed Serbia and issued an ultimatum. Because of the alliance system, the conflict spread rapidly: Austria-Hungary declared war on Serbia, Russia mobilized to defend Serbia, Germany declared war on Russia and France, and Germany's invasion of neutral Belgium brought Britain into the war. A regional dispute became a world war within weeks.
Exam tip: the assassination is a classic short-term cause or trigger, never confuse it with the long-term MAIN causes.
Total War and New Technology
World War I introduced total war, in which entire economies and civilian populations were mobilized for the war effort. Governments rationed food, directed factories, and used propaganda. On the Western Front, armies dug into trench warfare, a deadly stalemate of mud, barbed wire, and no-man's-land.
Industrial technology made the killing efficient:
- Machine guns mowed down infantry charges
- Poison gas (chlorine, mustard) caused horrific casualties
- Tanks and artillery broke through fortified lines
- Submarines (U-boats) sank ships, including the Lusitania, helping draw the United States in (1917)
- Airplanes introduced aerial combat and reconnaissance
The result was unprecedented slaughter: roughly 9 million soldiers died, and the war is sometimes called the first modern industrialized conflict.
Which of the following best illustrates a long-term cause of World War I rather than its immediate trigger?
Ending the War: Versailles and Its Effects
When the fighting stopped with the armistice of November 11, 1918, the victors met in Paris. U.S. President Woodrow Wilson proposed the Fourteen Points, including national self-determination and a League of Nations to prevent future wars. But the final Treaty of Versailles (1919) was far harsher than Wilson wanted:
- The War Guilt Clause (Article 231) forced Germany to accept full blame for the war
- Germany paid enormous reparations it could not afford
- Germany lost territory and colonies and was forced to disarm
- New nations (Poland, Czechoslovakia, Yugoslavia) were carved from the fallen empires
The treaty created the League of Nations, but the U.S. Senate refused to join, weakening it from the start. German resentment over the "war guilt" and reparations became fuel for extremist politics in the 1920s and 1930s, a direct line to World War II.
Collapse of Empires
Four multinational empires collapsed as a result of the war: the German, Austro-Hungarian, Russian, and Ottoman empires. Their collapse unleashed nationalism, redrew the map of Europe and the Middle East (mandates), and created power vacuums.
The Russian Revolution of 1917
Russia entered the war militarily weak and economically strained. Massive casualties, food shortages, and the failures of Tsar Nicholas II produced revolution.
Two revolutions occurred in 1917:
- March (February) Revolution — Strikes and mutinies forced Nicholas II to abdicate, ending the Romanov dynasty. A weak Provisional Government took over but kept fighting the war, which was deeply unpopular.
- November (October) Revolution — Vladimir Lenin and the Bolsheviks (a radical Marxist party) seized power with the slogan "Peace, Land, and Bread." Lenin pulled Russia out of World War I through the Treaty of Brest-Litovsk (1918), surrendering territory to Germany.
A brutal civil war (Reds vs. Whites) followed, ending with Bolshevik victory and the creation of the Soviet Union (USSR) in 1922, the world's first communist state. Lenin built on the ideas of Karl Marx, who had argued in The Communist Manifesto (1848) that workers (the proletariat) would overthrow the owning class. Exam tip: the Russian Revolution is a textbook turning point and an example of political and economic systems changing dramatically.
Connecting to the Exam
Expect questions that ask you to match a cause with an effect, identify the trigger versus the underlying causes, or read a political cartoon or treaty excerpt about Versailles. The enduring issue of conflict runs through this entire section.
