Libertyville HS

Long Range Causes of WWI

• Militarism– Large standing armies– Arms race (ex.

battleships)– Quick mobilization

• Alliances– “Triple Entente”

• Great Britain, France, Russia

– Triple Alliance• Germany, Austro

Hungary, Ottoman Empire

Long Range Causes of WWI• Imperialism

– Quest for colonies brought conflict

– Ex: Berlin Conference / Africa

• Nationalism– Intense love of country– Created competition – National rivalries

developed over territory (Russia vs. Austro Hungary; Germany v. France)

Short Term Cause of WWI

• Assassination of Archduke Ferdinand– Heir to Austro-Hungary throne– Gavrilo Princip (Black Hand)– AH: declared war on Serbs– Russia declared war on AH– Chain reaction of war

declarations, due to alliances– Map to show beginning of war

“The German Right Hook”• Germans strike first

– Schlieffen Plan (1905)• Plam to avoid a 2 front

war• 90% of German army =

attack through Belgium• 5% hold Russian border• 5% defend French border

– Later changes to plan• Driven by Nationalism• Weakened R. hook• Strengthened defenses

Schlieffen Plan, in Action

• Schlieffen plan failed• French mobilized too

quickly!• Right hook slowed

down by British, in Belgium; too weak to finish beyond Paris

• German defenders of A-L too strong

War in Europe – the West• Triple Entente = French

and British• Triple Alliance =

Germans

• Trench Warfare– 300 mile long system of

defensive ditches dug from Swiss border to North Sea

“Over the Top”The Myth

The Reality

“No Man’s Land”

In the East

• Main combatants– Triple Entente =

Russia– Triple Alliance =

Austrians (& Germans)

• Few trenches; instead, a war of maneuver

WWI in SW Asia• Main Combatants

– Triple Entente = Britain and it’s empire (ANZAC)

– Triple Alliance = Ottoman Empire

• Allied goal was a “Third Front” to drain German / Austrian troops from other theaters

Unsuccessful: Gallipoli

• Assault on the Dardanelles, by British and ANZAC troops

• Slaughter, on both sides– About 250k casualties

on each side (stalemated)

Successful: Lawrence of Arabia

• British officer who welded Arabians into army against Turks

• Hit and run raids on horses, camels

• Eventually took most of SW Asia for the British

1917-18: End of WWI

• In East, Russian Communist Revolution in October 1917 took Russians out of war– Freed up 100,000s of

German troops for Western Front

– Russian Soviets made peace w/ Germans in 1918

End of WWI, Western Front

• American Entered war, 1917– Americans entered

war just as British, French troops reached breaking point

– Fresh soldiers, equipment critical to Triple Entente’s success

End of WWI, Western Front

• Germans attempted to win it all at the Somme– After initial success,

offensive ground to a halt

– Germans set up for big losses after overextending army

Collapse of Central Powers• Bulgarians signed

armistice (peace treaty) first, in 9/18

• Ottomans surrendered 10/30/18

• Austrians knocked out on 11/3/18

• German state underwent revolution, overthrowing Kaiser, and became republic on 11/9/18

Collapse of Central Powers

• On 11-11-18, at 11 am, Germany signed armistice to end fighting

• Armistice signed in railroad car in France

Treaty of Versailles• Required Germany to pay

massive war reparations to allies– Germany couldn’t pay, so

borrowed $ from USA– German economy collapsed

(hyper inflation) as the DM became worthless

• Treaty blamed Germans for the war (“War Guilt Clause”)

Treaty of Versailles• Treaty caused bitter

feelings in Germany– “Stabbed in the back”

theory: no foreign troops on German soil!

– Nationalist parties came to power in Weimar Republic

– Example: National Socialist Workers Party, aka Nazis
