World War I was caused by militarism, alliances, imperialism, and nationalism in Europe leading up to 1914. The immediate trigger was the assassination of Archduke Ferdinand by Serbian nationalists. This caused Austria-Hungary to declare war on Serbia and drew in allies on both sides through a series of interlinking alliances. The war became global and total war as more countries joined and all domestic resources were devoted to the war effort. Fighting lasted from 1914-1918 and was especially deadly and prolonged on the Western and Eastern Fronts. The U.S. entry into the war in 1917 helped ensure an Allied victory. After huge losses, the war finally ended with the defeat of Germany and the Treaty of
2. MAIN Causes of WWI
Militarism
Alliances
Imperialism
Nationalism
3. Cause: Militarism
All major nations wanted a
large army in response to
nationalism, imperialism
and the perceived threats
from other armies
4. Cause: Alliances
Caused many countries to join
fighting once war had begun
Before the war: Triple Alliance
and Triple Entente
Later: Central Powers and
Allied Powers
6. Cause: Nationalism
Desire to prove national
greatness led to rivalries
between great powers
Highly nationalistic ethnic
groups were calling for
independence (e.g.,
Serbians, part of Slavic
ethnic group)
7. Ottoman Empire
had declined and
some Balkan
countries were
now independent
Austria took over
(annexed) Bosnia
and Herzegovina,
part of Slavic
ethnic group
Serbia, also Slavic,
resented Austrian
aggression;
wanted large
Slavic-controlled
region
The Catalyst:
Background
8. The Catalyst

Ferdinand of Austria-Hungary
Serbian nationalist group, Black Hand,
wanted Bosnia freed from Austria
19-year-old Gavrilo Princip of the Black
Hand killed the Archduke on June 28,

set demands; most agreed to, but
not enough
Austria declares war against
Serbia on July 28, 1914
10. War Spreads
July 28Russia (also
Slavic) mobilized troops

Aug 1Austrias ally
Germany saw this as a
threat and declared war
on Russia
11. War Continues to Spread
Aug 3Germany declared
war on France, Russias ally
Aug 4after Germany
attacked neutral Belgium, to
get to France, Britain
declared war on Germany
12. The Schlieffen Plan
Firstattack France to the west
Secondattack Russia to the
east
Worked well to start: in Paris by
Sept 3
Intended to keep Germany from
having to fight on two fronts at
the same time
14. Alliances Before the War
Triple Alliance:
Germany, Austria-Hungary, Italy
Triple Entente:
France, Russia, Britain
15. Alliances Shift After War Starts
Central Powers
Germany, Austria-Hungary
later, Bulgaria and Ottoman
Empire (wanting to regain lost
territories)
16. Allied Powers (the Allies)
Great Britain, France, Russia
soon Japan, and later Italy
also Serbia, Greece, Romania,
etc.
much later, the U.S. (1917)
18. Short war goes long
German plan worked well to
start: in Paris by Sept 3
Battle of the Marne began on
Sept 5, after 8 days of battle,
German offensive was
stopped
Russians soon attacking
Germany in the east
the Schlieffen Plan has failed
19. Stuck in the trenches
Battle of Verdun in Feb 1916each
side lost more than 300,000 men
20. The western and eastern fronts
Investigate the Western and Eastern Fronts and annotate the map
provided to identify where they were in Europe. Find and record
information on the nations involved on each front and the casualties
suffered.
22. New technology of war
Machine guns
Poison gas
Grenades
Armored tanks
Larger artillery: canons
Submarines
Airplanes armed
with machine guns
23. Western Front
Mostly in France, near German border
500 miles of trenches dug in France
Trench warfare
No Mans Landthe uninhabited land between the rows
of trenches
STALEMATEstuck, nobody makes any real progress
24. Battles of the western front
