officially-ends/videos#causes-of-world-war-i

Militarism• Aggressive strengthening of armed forces

• Nations compete to build the largest, strongest armies and navies

Alliances

• Partnerships, for protection.– Originally

formed to maintain peace

– But would lead directly to war.

Germany, Austria-Hungary, Italy

• 1879 - Germany formed a military alliance with Austria-Hungary and Italy called the Triple Alliance.

France & Russia

• Fought over Africa, China, and the Middle East

Nationalism

• Pride and loyalty to ones nation

• Caused tension in Europe

The Spark That Lit The Fuse….

• The one event that started the Great War happened in the Balkans.

• Archduke Franz Ferdinand (Austria) was visiting Serbia.

• http://www.awesomestories.com/assets/assassination-of-archduke-franz-ferdinand-2

• Austro-Hungarian officials learned the Serbian government supplied the assassins with weapons.– They blamed Serbia for

the killing

Gavrilo Princip

Kaiser Wilhelm II

• Russia had vowed to protect Serbia– Russia’s army began to

mobilize.• Germany, as Austria-

Hungary’s ally, declared war on Russia– And two days later,

declared war on France“You will be home before

the leaves have fallen from the trees!!”

WWI Alliances

• Central Powers– Germany– Austria-Hungary– Later

• Bulgaria• Ottoman

Empire

• Allied Powers– France – Russia– Britain– Later

• Italy

• Both sides expected a quick war• Germany planned to defeat France before

Russia could join in– But met resistance from Belgian soldiers

• Gave Britain and France had time to mobilize

First Battle of the Marne

Schlieffen Plan• To get to France, Germany would cross

through neutral Belgium

• Germany came within 25 miles of Paris• The French army blocked the advance at the

Marne River

• The battle lasted several days• It became clear the war would be longer and

deadlier than expected

A New Kind of War

• Trench Warfare• New Technology• Poisonous gas• Tanks• Airplanes• U-boats

WWI Firsts• http://www.history.com/topics/world-war-i/

videos#wwi-firsts

Trench Warfare

• Soon a 400-mile-long network of trenches stretched cross the western front

• After the Battle of the Marne the Germans dug trenches nearby to defend their position

• The French dug their own trenches

• Trenches were cold, wet, and muddy– Breeding grounds for germs

• Soldiers fought in them for months at a time– Soldiers on both sides died from disease

Trench Foot

No Man’s Land• An empty patch of ground, about 25-foot

to 1 mile distance , between enemy trenches– Stripped of trees and blasted full of

holes– Those who

dared to venture out would likely be killed

New Technology• New machine guns could fire 400 – 600 bullets a

minute• Artillery guns fired shells over the trenches

– They sent speeding scraps of metal onto the soldiers

Poisonous Gas• Some shells spread poisonous

gases– Which would destroy the

lungs– And cause slow painful death

• Soldiers living in trenches were surrounded by machine-gun fire, flying grenades, and exploding artillery shells.

– Opposing forces had machine guns pointed at enemy trenches at all times

– And fired whenever a helmet or rifle appeared over the top.

Tanks• British forces developed armored tanks

to move into no-man’s-land.• Success was limited

– many got stuck in the mud.

• The Germans found ways to destroy the tanks with artillery fire.

Airplanes

• Air battles were called dogfights.

• Both sides used planes – to map and attack trenches

• Planes first dropped bricks and heavy objects– They soon mounted guns and

bombs

Land and Sea Battles

• By 1916, after only a year of fighting, the war had become a stalemate– Neither side could win a decisive victory

• Then both sides launched massive attacks– Germans attacked Verdun, France– Allies attacked along the Somme River– Attack, counterattack, but no change

• Except - nearly 1 million men died

The Western Front• http://www.bbc.co.uk/history/worldwars/

wwone/launch_ani_western_front.shtml

Battle at Sea• The British navy blockaded the ports of the

Central Powers– They laid explosive mines– That stopped ships from supplying the

Germans

German U-boats• German submarines• Launched torpedoes against Allied supply ships

– Also attacked ships of neutral countries

Americans Prepare for War

Divided Opinion

• Woodrow Wilson announced the United States would remain neutral

• Most Americans agreed

Neutral Ships• Even with a policy of

neutrality, American ships carried supplies and war materials to the Allies

• U-boats attacked to stop the supplies

• Sometimes without warning

The Lusitania• http://www.history.com/topics/world-war-i/
