“One archduke more or less makes little difference.”
- The Grand Forks, North Dakota Daily Herald
Chapter 18.1 A World Crisis

2. Focus Your Thoughts . . . What is ‘isolationism’?
What are its benefits and detriments?
“Armed neutrality is ineffectual at best.”
- Woodrow Wilson, 1917
What did Wilson mean by this quote?

3. How could one assassination start a world war??
Causes of World War I
Some 3,000 miles away from Sarajevo, most Americans cared little about the news of Archduke Franz Ferdinand’s assassination
Most of Europe felt the opposite, and plunged into war within weeks . . .
How could one assassination start a world war??

4. Let’s Back Up . . . Where is Sarajevo?
Central Europe: Then
Central Europe: Now
Sarajevo is the capital city of Bosnia and Herzegovina, it was ruled during this time period by the Austro-Hungarian Empire

5. Causes of World War I Also known as the ‘Great War’
Nationalism: Most visible in the Balkan’s where the Ottoman Empire was starting to crumble; Austria-Hungary saw an opportunity and tried to push into the region
Imperialism: By the late 1800’s, Great Britain and France already had colonial empires in Africa, the Middle East, and Asia; the German Emperor Kaiser Wilhelm II, wanted colonies for Germany too.
Militarism: The policy of military preparedness and building up weapons; Germany began to enlarge both it’s army and navy
The Schlieffen Plan – Precise instructions for waging a two-front war against Russia and France by passing through Belgium leading the other nations to take notice

6. The Alliances The Balance of Power
The Triple Alliance
(The Central Powers)
The Triple Entente French for ‘understanding’
(The Allied Powers)
Germany
Italy
Austria-Hungary
Great Britain
France
Russia
What is an ‘alliance’? Why would they feel it was necessary to form them?

7. War Breaks Out
After the assassination of Archduke Franz Ferdinand, Serbian teenager Gavrilo Princip of the Black Hand, was arrested
After investigating his background, Austro-Hungarian officials discovered that the government had been supplying the Black Hand with weapons
Austria-Hungary declares war; because Austria-Hungary is part of The Triple Entente, Russia begins to prepare for war as well which Germany considers a hostile act Germany responds by declaring war on France

8. The Germans Take Belgium
On August 4, 1914, German troops cross the border into the neutral country of Belgium; because Great Britain had promised to defend Belgium, they declared war on Germany
At first the Schlieffen Plan worked well; the German attack on Belgium was fierce
Germans burned entire villages, executing women and children along the way

9. A New Kind of Warfare
The French rushed to meet the German’s in bright red uniforms, while the German’s wore gray which worked expertly as camouflage
French military strategy hadn’t changed much since the 1800’s, and the French were stunned, when given the orders to ‘charge’ and drew their weapons when they were met by a hail of machine gun and artillery fire
15,000 French soldiers were dying per day

10. The First Battle of the Marne
The Germany army quickly advance through France
Desperate for a victory, the French launched a daring counterattack
2 million men fought for five days straight
250,000 died
However . . .
The French rallied and pushed the Germans back forty miles, allowing Russia time to mobilize

11. The War Reaches a Stalemate
The First Battle of the Marne ended in a standoff
Both sides began to dig trenches, or deep ditches to protect them and help them defend their positions
Trench warfare – Fighting from within the trenches
Soldiers lived in the trenches, surrounded by constant machine gun fire, flying grenades, and exploding artillery shells
Opposing forces had their machine guns aimed at enemy trenches at all times
The area in between the trenches became known as “no man’s land”

12. If either side is ever going to win, something’s gotta give . . .
More New Weapons
Scientists for both alliances worked to develop new weapons in an attempt to win an advantage:
Chlorine gas –
Attacked and destroyed the lungs of soldiers
Lead to the introduction of the gas mask
Had little impact on battles because the gas was not colorless, as long as soldiers could see it coming, they could avoid the attack
Airplanes –
Not a new invention, but new in terms of it’s being used to conduct attacks
Tanks –
Scared the German soldiers, but they weren’t especially successful because they often got stuck in the mud
If either side is ever going to win, something’s gotta give . . .
