World War I The War to End All Wars 1914 - 1918

MAIN Causes of War• Militarism – Buildup of armed forces.

Preparing for war.

• Alliance System – Agreements or promises by a country to help defend other countries

• Imperialism – Trying to build an Empire.

• Nationalism – Having pride in your country and willing to defend it.

MAIN Causes of War• Militarism

– By 1890 most European Countries had large armies ready to assemble quickly.

• Alliances– Triple Alliance (Formed in 1882)

• Members: Germany – Austria / Hungary – Italy• Problem – Triple Alliance had a treaty w/ Russia. Russia and Austria were

bitter rivals for control of the Balkans.– Triple Entente (Formed in 1907)

• France – England – Russia• Formed as a result of German aggression towards Russia.• Problem – Borders not aligned geographically

• Imperialism– Competition for resources in Africa and Asia

• Rise of Nationalism– Intense Rivalries – Competition for Resources– Territorial Disputes

Crisis in the Balkans• Serbia – Had the desire to annex

the Balkans into one country. (Most of these countries were native Slavs.)

• Austria – Hungary – Had the desire to annex all of the Balkans. Had support of Germany and annexed Bosnia in 1908.

• Russia – Supported Serbia’s quest to unify the Balkans into one nation. Offered Serbia full support but backed down when Germany supported Austria – Hungary.

The Spark!• Leader of Austria – Hungary Archduke Franz Ferdinand

assassinated! – June 28, 1914• Killed by a member of “The Black Hand” secret society with

the intent on freeing Bosnia from Austrian rule.• Austria-Hungary uses this action to punish Serbia.• With German support, Austria-Hungary presents Serbia with

an ultimatum. – July 23, 1914

A Disastrous Chain of Events• July 28, 1914 – Austria – Hungary declares war on Serbia.• Russia vows to protect Serbia and mobilizes troops.• August 1, 1914 - Germany views this as an act of aggression and

declares war on Russia.• August 3, 1914 – Germany declares war on France.• Germany enacts the Schlieffen Plan and invades Belgium, a neutral

country, to get to France.• August 4, 1914 – Britain declares war on Germany for violating

Belgium’s neutrality.• Italians change their alliance to the Triple Entente nine months after

the war began, claiming they did not agree with Germany’s invasion of Belgium.

The Schlieffen Plan

• German Strategy to win the war quickly.• Named after it’s creator General Schlieffen.• Plan– Sweep west and defeat France quickly with a

surprise attack.– Return east after defeating France to defeat a

weaker Russian army.– Had to invade Belgium due to time constraints

after Belgium refused to get involved.

When Battle Plans Fail: Stalemate

• Plans Fail– Plans are based on false assumptions of enemy strength– Schlieffen invasion starts well, ends bad

Belgium and France do not have the infrastructure to support German advance– Battle of the Marne• 600 taxi cabs rush French & British forces to the battle• Hold line 40 miles from Paris• Stalemate on the Western Front
