Review Questions

Why did Gavrilo Princip join a terrorist organization?

What happened within a few weeks of the assassination of archduke Franz Ferdinand

Causes of World War 1

NationalismOttoman Empire was falling apart and being

Africa, Asia, and the Middle EastKaiser Wilhelm II of Germany wanted colonies

for Germany too, and realized he needed a stronger military to accomplish this

Militarism- the policy of military preparedness and building up of weaponsGermany begins to build up a navyGermany enlarged its army and supplied it

with the latest weapons including machine guns

Germany began to develop a military plan called the “Schlieffen Plan” in which attacks France and Russia at the same time

Great Britain, France, and Russia began to become alarmed and start building up their militaries in preparation

AlliancesSome nations formed alliances or partnerships to

protection and to maintain peaceGermany, Austria-Hungary, Italy for the Triple

Belgium and Britain were allies which drew Great Britain into the war.

All European powers were splitGermany, Austria-Hungary, and Ottoman

Empire “Central Powers”Great Britain, France, and Russia form the

“Allies”

Germany attacks Belgium and easily defeats their army: villages are burnt down, civilians, women, & children are executed

French army mobilized in their bright red uniforms and brass helmets to face a German army dressed in grey uniforms

French soldiers marched row by row onto the battlefield with bayonnets expecting hand to hand combat only to face machine gun fire

War began in the summer and Germany predicted a quick victory

Expected to be home by fall Were killing 15,000 French soldiers each day On Sept. 7, France launched a counterattack

known as the First Battle of the Marne In a 5 day battle, 250,000 lives were lost, and

France managed to push Germany back 40 miles.

Battle of the Marne provided time for Russia to mobilize

Germany had to move troops from its attack on France to face Russia

The War Reaches a Stalemate

First Battle of Marne ended in a stalemate French and German armies dug trenches

to defend their positions and protect themselves from fire

Trenches reached more than 400 miles Neither side was able to advance and they

faces a stalemate

Scientists on both sides began developing new weapons

German scientists began to develop poisonous gas

Also developed gas masks as protection This also produced a stalemate

British developed the first armored tank In the 1st battle these were used in, 18 out of 48

got stuck in the mud Airplanes became useful to map enemy

positions and attack the trenches from above Airplane pilots became involved in spectacular

air battles called “dogfights”

Bellringer /Section 2 PreviewWould you travel into a war zone? On May 1st 1915,

some 1900 passengers and crew boarded the British luxury ship, Lusitania in New York. They were headed for Great Britain, which was in a war zone. The nervous passengers had been told that the ship was too fast for any German submarine. On the afternoon of May 7th, as the ship approached the British Isles, a crew member spotted ominous air bubbles and streaks in the water below. The ship had been attacked by German torpedos. 18 minutes later, the Lusitania sank. More than 1200 people including 94 children died. Among the dead were 128 Americans

Review Questions

What assurance were passengers given about taking the Lusitania into a war zone?

What was the first sign of trouble?

What did it indicate?

The United States stays neutral

Before the sinking of the Lusitania, Americans were unconcerned about the war

President Woodrow Wilson embraced a policy of Isolationism- a policy of not being involved in the affairs of other nations

Despite his policy of neutrality, United States was leaning toward the allies.

Concerned about Germany’s war tactics Had commercial/trade ties to Great Britain Great Britain was buying $75 million of war

goods each week

Germany’s naval strategy Great Britain created a blockade against

Germany Germany planned a strategy against the British

navy using U Boats- small submarines 1915 Germany declared all water against Great

Britain a war zone and that it would destroy any ship, even neutral U.S. ships in that area

This policy angered American citizens President Woodrow Wilson believed this violated

the Laws of Neutrality President Woodrow Wilson advised they would

hold Germany responsible if any American lives were lost.

Heading for War Sinking of Lusitania angered American citizens President Wilson demanded an end to

unrestricted submarine warfare Germany agreed to only attack supply ships Less than one year later, Germany attacked a

French passenger ship, the Sussex U.S. threatened to enter the war Germany made the Sussex Pledge, which was a

pledge not to attack without warning and without saving human lives

Transport ships were surrounded by destroyers for protection

Convoy system was effective in reducing the loss of ships and lives

By the time the Americans arrived, Germans occupied all of Belgium and part of Northern France

Germany was beginning to defeat Russia, who was facing civil war and starvation

Russia was taken over by the Bolsheviks, a communist group who withdrew Russia from the war and signed a peace agreement with Germany

By March 1918, Germany had pushed the Allies back 70 miles from Paris

American soldiers had to dig 3,000 yards of trenches and set up 12,000 yards of barbed wire which they did in the middle night

In the trenches, soldiers stood in deep mud as rats ran across their feet, shells exploded nearby, mustard gas floated into the trenches
