#AP US History: World War I - The Final Countdown π
Hey there, future AP champ! Let's get you prepped and pumped for the big exam. We're diving into WWI, focusing on what you really need to know. Think of this as your ultimate cheat sheet, designed to make everything click. Let's do this!
#1. Road to War: The Spark and the Tinderbox π₯
#Causes of World War I
Remember M.A.N.I.A. to nail the key causes. It's like a recipe for disaster, and Europe had all the ingredients:
- Militarism: Countries were in an arms race, building up their militaries like there was no tomorrow. βοΈ
- Alliances: A tangled web of secret agreements meant a small conflict could quickly escalate. Think of it like a group project where everyone has a side hustle. π€
- Nationalism: Extreme pride in one's country, leading to the belief that they were superior. It was like a global competition of who could be the most arrogant. π
- Imperialism: European powers were competing for colonies and resources, creating tension and resentment. π
- Assassination: The assassination of Archduke Franz Ferdinand was the spark that lit the fuse, but the underlying tensions were already there. π₯
#The Sides
| Central Powers | Allies |
|---|---|
| Germany | Serbia |
| Austria-Hungary | France |
| Ottoman Empire | Great Britain |
| Russia (until 1917) | |
| USA (after 1917) |
Key Point: WWI wasn't just about one event; it was a culmination of long-standing rivalries and aggressive policies.

#2. US Stance: From Neutrality to the Trenches πΊπΈ
#Initial Neutrality
- Washington's Ghost: The US initially wanted to stay out of Europe's mess, following George Washington's advice against foreign entanglements. π ββοΈ
- Woodrow Wilson: President Wilson aimed for neutrality, partly due to the diverse immigrant population in the US and partly to play peacemaker. ποΈ
#The Shift
- Economic Ties: The US was loaning way more money to the Allies than the Central Powers, creating a pro-Allies bias. π°
- German U-Boats: German submarines attacked ships, including the Lusitania, killing 123 Americans. π’
- Zimmerman Telegram: Germany's attempt to get Mexico to attack the US was the last straw. βοΈ
- Unrestricted Submarine Warfare: Germany's decision to sink all ships in war zones pushed the US to declare war.
- Wilson's War Aims: Wilson framed the war as a fight for democracy and against tyranny. "Make the world safe for democracy!" π½

#3. Getting Ready: Preparedness and Mobilization βοΈ
- Preparedness Movement: Many Americans realized the military was weak and pushed for greater defense spending.
- National Defense Act (1916): Wilson expanded the army and navy, showing the US was getting serious. πͺ
- Selective Service Act (1917): The US instituted a draft, registering millions of men for service. π
- American Expeditionary Force (AEF): Led by General John J. Pershing, the AEF saw significant action in Europe. πΊπΈ
#4. US in Combat: A Taste of Trench Warfare πͺ

- Casualties: The US suffered over 112,000 fatalities, including many from a flu epidemic. π₯

- Army: Germany had to reduce its military significantly. πͺ
- Territory: Germany lost colonies and territory in Europe. πΊοΈ
- League of Nations: Established as part of the treaty, but with a lot of problems.
Common Mistake: Don't confuse Wilson's Fourteen Points with the Treaty of Versailles. They were very different in tone and goals.
#7. Senate Rejection: Isolationism Prevails ποΈ
- Senate Opposition: The US Senate rejected both the Treaty of Versailles and the League of Nations, especially Article X.
- Article X: This article would have forced the US to get involved in international conflicts, which many senators opposed.
- Wilson's Tour: Wilson tried to rally public support but suffered a stroke, making it impossible to compromise. π€
