2. Causes

3. World War 1: Overview
First total war in history (soldiers & civilians)
In August 1914 it involved only 7 European countries but by November 1918 there were over 30 countries fighting
Battles were fought in Europe, Asia, Africa, & on/under the Atlantic & Pacific Oceans
Resulted in revolutions, changes of govts., loss of empires, the rise of great new powers, & millions of dead

4. World War I: Causes
While the assassination of Archduke Franz Ferdinand was the immediate cause of the war, there were four underlying causes of WWI.
They are:
a). Militarism
b). Alliances
c). Imperialism
d). Nationalism

5. Militarism
The belief in the power of strong armies or navies to decide issues.
It was thought that the only way to guarantee peace was to prepare for war.
Based on the idea that if a nation is strong, then no enemy would dare to attack it.
If war does break out, the militarized nation is able to defend itself.

6. Militarism
Militarism led to an arms race before 1914 as each country tried to build a larger & more deadly war machine than its rivals.
The size of armies & navies would determine who was more powerful.
Germany contained Europe’s strongest armies while Great Britain was the world’s strongest naval power.
Gr. Britain felt threatened when Germany began to construct a large navy.
European nations were becoming increasingly suspicious & alarmed by the others’ military power.

8. Alliances
Alliances are formed when countries band together against a common threat.
In 1914 we had two alliances:
1.The Triple Alliance (“The Central Powers”) consisting of Germany, Austria-Hungary, & Italy
2. The Triple Entente (“The Allies”) consisting of Great Britain, France, and Russia

13. Imperialism
Imperialism is the policy of establishing colonies away from the homeland & building an empire
Colonies provided raw materials, markets for goods, & military strength for many European countries.
Great Britain, France, Russia, Germany, the United States all wanted to build a colonial empire.
Imperialism led to frequent quarrels among the great powers of Europe in all parts of the globe.
Arguments over colonies & trade constantly threatened peace.

16. Imperialism in Asia

18. Nationalism
Nationalism is a feeling of deep loyalty to one’s people & homeland
Extreme nationalism was causing problems in the early 20th century.
Some people seemed willing to take any action to support their nation, regardless of the effect on others
They were even ready to go to war to promote the interests of their homelands

19. Nationalism
The Black Hand was a Serbian-Bosnian terrorist group that thought Bosnia should break away from Austria and be united with Serbia.
Franz Ferdinand was killed by a Serb nationalist Gavrilo Princip, who belonged to the Black Hand, while visiting Sarajevo.
Franz Ferdinand was the heir to the
Austro-Hungarian throne.

21. Ultimatum......July 1914
The Austro-Hungarian (A-H) govt blamed Serbia for the archduke’s death & attempted to crush Serb nationalism
With the support of Germany, A-H sent the Serbian govt an ultimatum (A ultimatum is a demand by one govt that another govt accept its terms or face war) to Serbia
a). put down all Serb nationalism against A-H
b). Punish those involved in the assassination
c). Allow A-H into Serbia to help destroy the Black Hand
Serbia accepted all except the last request

23. Outbreak
Austria declared war on Serbia when Serbia rejected the Austrian ultimatum.
Russia, Serbia’s ally, along with France, mobilized their armies.
Germany declared war on both Russia & France when both countries refused to demobilize.
Germany planned to attack France through neutral Belgium
Britain declared war on Germany when Belgium was invaded
