#AP US History: Interwar Period & Road to WWII π
Hey there, future AP historian! Let's get you prepped for the exam with a super-focused review of the interwar period and the lead-up to World War II. We'll break it down, make it memorable, and get you feeling confident! πͺ
#Post-WWI: A Return to "Normalcy"?
#The US Steps Back (Kind Of)
- Return to Normalcy: President Harding's slogan meant less European entanglement, but not complete isolation.
- Limited Engagement: The US still had colonies, wanted global trade, and sought to prevent future wars through treaties.
#Attempts at Peace and Stability
- Washington Conference (1921): Tried to limit naval arms races, with a focus on battleship ratios.
*
US, UK > Japan > France, Italy
US aimed to curb Japanese naval power in the Pacific.
Think of it like a pinky promise between countries β nice in theory, but not very effective.
#The Dawes Plan: A House of Cards π
- US Banks loaned money to Germany β Germany paid reparations to UK & France β UK & France repaid US banks for WWI loans β repeat.
This cycle worked until the Great Depression hit the US, and the whole thing collapsed.
Practice Question
Multiple Choice:
-
The Washington Naval Conference of 1921 was primarily intended to: (A) Establish a new international peacekeeping organization. (B) Limit the naval arms race among major powers. (C) Promote free trade and economic cooperation. (D) Resolve territorial disputes in Europe.
-
The Kellogg-Briand Pact of 1928 is best characterized as: (A) An effective treaty that prevented future wars. (B) A symbolic agreement lacking enforcement mechanisms. (C) A military alliance between the United States and European powers. (D) A plan for economic recovery after World War I.

#American Isolationism & The Rise of Totalitarianism
#The World Goes Dark π
- Totalitarian Leaders: Hitler (Germany), Mussolini (Italy), Stalin (USSR), and Tojo (Japan) rose to power, embracing nationalism, militarism, and expansion. *
Totalitarianism = state control of all aspects of life
#US Stays Out (For Now)
- Isolationism: Despite concerns, most Americans supported staying out of international conflicts.
- Key Events: Japan invaded China, and Germany invaded Poland, starting WWII, but the US remained neutral.
#Good Neighbor Policy
#Focus on Latin America
- No Intervention: FDR pledged not to interfere in Latin American internal affairs.
- Arbitration: Committed to resolving disputes through negotiation.
- Hemispheric Unity: Warned that any European aggression would be met with a united response from the Americas.
#Neutrality Acts
#Keeping the US Out of War
- Restricted Trade: Made it difficult to trade with warring nations to avoid WWI-like entanglements.
Remember: These acts were designed to keep the US neutral, but they also limited our ability to help allies.
Practice Question
Multiple Choice:
-
The Good Neighbor Policy, initiated by President Franklin D. Roosevelt, primarily focused on: (A) Increasing US military presence in Latin America. (B) Promoting economic development in Asia. (C) Improving relations with Latin American countries. (D) Isolating the United States from international conflicts.
-
The Neutrality Acts of the 1930s were primarily designed to: (A) Provide financial aid to Allied nations. (B) Prevent the United States from being drawn into another war. (C) Increase US military preparedness. (D) Encourage trade with both Allied and Axis powers.
Short Answer Question:
Explain how the Neutrality Acts reflected the prevailing sentiment of isolationism in the United States during the 1930s.
#US Assistance to the Allies (Slowly but Surely)
#Cash and Carry
- British Purchases: Allowed the UK to buy war materials from the US, but they had to pay cash and transport it themselves. *
This was a way to help without direct involvement.
#Lend-Lease Act
- Financial and Material Aid: Allowed the US to lend money and materials to the UK, China, and the USSR. *
This was a major step away from neutrality.
#Selective Service Act (1940)
- First Peacetime Draft: The US began mobilizing for war.
#Opposition to Intervention
- America First: Led by Charles Lindbergh, this group advocated for isolationism. *
Don't confuse this with the 'America First' policies of other eras - they are not the same!
#The Catalyst: Pearl Harbor
- December 1941: The Japanese attack on Pearl Harbor led to full-scale US involvement in WWII.
#Nazism and the United States
#The American Bund
- Pro-Nazi Group: Promoted fascist ideology in the US, led by Fritz Julius Kuhn.
- Public Rallies: Held large rallies and tried to recruit German-Americans. *
This highlights the presence of extremist ideologies in the US during this time.
#A pro-Nazi rally in Madison Square Garden
#The US is Pushed Into War
#Pearl Harbor: The Breaking Point
- "Day of Infamy": FDR's description of the attack.
- Declaration of War: The US declared war on Japan, Italy, and Germany.

-

(D) A pre-emptive strike by the United States against Japanese forces.
