The Great War 1914-1918
Underlying Causes of WWI
• Militarism
– a policy of aggressive military preparedness, military
values/goals take over civilian society
• Alliance System
– an association to further common interests of the members and
in this context, nations. (Triple Entente and Triple Alliance)
– nations pledged to intervene if an ally was attacked
• Imperialism
– Possession of overseas colonies. Competing claims created an
atmosphere of tension between major powers
• Nationalism
– loyalty and devotion to a nation, placing primary emphasis on
promotion of its culture and interests, encouraged rivalries
Section 2: Rivalries Lead to War
Spark that ignites the War
• States in southeastern Europe had struggled to
free themselves of Ottoman rule
• Rivalry between Austria-Hungary and Russia for
control of these new states created serious
tensions
• 1914, Serbia, supported by Russia, was
determined to create a large, independent
Slavic state in the Balkans
• Austria-Hungary determined to prevent this
from happening
• June 28, 1914, Archduke Francis Ferdinand,
heir to the Austria-Hungary throne, and his
wife Sophia visited Bosnian city of Sarajevo
• Members of the Black Hand, a Serbian
terrorist group that wanted Bosnia free of
Austria-Hungary, planned to kill the Archduke
• First assassination attempt failed, but Gavrilo
Princip succeeded in shooting and killing both
the archduke and his wife.
• Assassination set off a chain reaction in
Europe
• Austrian leaders wanted to attack, but feared
Russian intervention on Serbia’s behalf, so they
sought backing of their German allies.
• July 5, 1914 Germany issues A-H “blank check”
– pledging military assistance if A-H goes to war
against Russia

(extreme demands that Serbia rejected)

orders full mobilization
(assembling troops and
supplies and making
them ready for war) of
its troops

German troops
“Belgium is a country, not a road”

declared war on France
– Why???

Section 3: Fighting the Great War
Schlieffen Plan

two-front war by
concentrating troops in
the West and quickly
defeating the French and
then, if necessary, rushing
those troops by rail to the
East to face the Russians
before they had time to
mobilize fully.
Trench Warfare
• Trenches dug from English Channel to
Switzerland
• 6 to 8 feet deep
• Elaborate systems of defense
• Baffled military leaders
– Millions of young men sacrificed attempting the
breakthrough through “no man’s land”
• Diseases, lice, trench foot
• Trench Warfare video
Trench Warfare
• These new weapons made it easier to defend positions
than to attack
• New type of warfare baffled military leaders
• Soldiers dug miles of deep trenches to fortify positions.
• Trenches were separated by fields of barbed wire and
mines known as “no man’s land”
• Anyone who climbed out of the trenches faced instant
death from enemy machine gun fire
• Soldiers spent years in the trenches, facing shelling
from artillery fire for hours each day
• Since neither side could advance, fighting lines became
stationary
The changes of war
• New weapons crippled the
“frozen front”
– Poison gas (mustard gas)

• U.S. troops did not arrive in large numbers in
Europe until 1918
• Entry of the U.S. into the war not only gave the
Allied powers (Triple Entente) a psychological
boost, but also brought them a major new
source of money and goods
