The document summarizes the key causes and events of World War 1: 1) Militarism, alliances, nationalism, and imperialism contributed to rising tensions in Europe. The assassination of Archduke Franz Ferdinand sparked war after Austria-Hungary declared war on Serbia and the system of alliances pulled more countries into the conflict. 2) The U.S. remained neutral at first but was eventually drawn into the war in 1917 after German U-boats sank American ships and the Zimmermann Telegram proposed a German-Mexican alliance against the U.S. 3) Over 8.5 million troops were killed and over 21 million wounded or taken prisoner by the end of World War

1. U.S. and World War I

2. Causes of WWI – MANIA!
• Militarism - policy of building up a strong military to prepare for war,
military used as a tool for diplomacy
• Alliances – agreements between nations to provide aid and protect on
another
• Nationalism – extreme pride in one’s country, national interests should be
placed above international affairs
• Imperialism – when one country takes over another country economically
and politically.
• Assassination – of Austrian Archduke Francis Ferdinand

4. Alliances
• There were 2 major alliances in Europe before
WW1. Alliances were made to protect each
nation from attack
• The Triple Alliance – Germany, Italy, Austria
Hungry
• The Triple Entente – Russia, France, Britain

6. The Spark
• Archduke Franz
Ferdinand and his
wife Sophie are
assassinated by
Gavrilo Princip.
• He was a member of
the Serbian
nationalist group –
the black hand.

7. The Domino Effect
• Austria blamed Serbia for Ferdinand’s
death and declared war on Serbia.
• Germany pledged their support for
Austria –Hungary
• Russia pledged their support for Serbia.

8. • Germany declares war on Russia.
• France pledges their support for Russia.
• Germany declares war on France.
• Germany invades Belgium on the way to France.
• Great Britain supports Belgium and declares war
on Germany.

9. Who was fighting?
Allied Powers Central Powers
• Britain & its colonies
• France & its colonies
• Russia
• Italy
• United States
• Many more
• Germany
• Austria-Hungry
• Ottoman Empire
• Bulgaria

11. Stalemate
• Outdated military tactics and new technology quickly turn the war
into a stalemate
• Trenches were dug in France to protect soldiers and solidify gains.
The area between the Central Powers and Allied Powers was known
as no mans land.

13. New Technology

modern war.

Guns all see use in the war.

• the U-boats (sinking without warning)

• March 1916 Germany torpedoes the Sussex liner
• Sussex Pledge – agreement - Germany would stop attacking
ships if U.S. could get G.B. to lift blockade
• Election of 1916: Wilson wins on campaign promise to keep
the U.S. out of war

16. Neutrality Ends
Immediate Causes:
• Violation of Sussex - Germany announces the U-boats will
sink ships again - no warning
• Rev. in Russia- attempting democratic gov’t
now an acceptable ally
• Zimmermann Note (telegram from Germany to Mexico)
suggesting an alliance between them and promising to help
them recover the territories of TX,
NM, & AZ
* 1917 – U.S. had no option but to enter the war

19. Big IDEAS for the
U.S. entrance

repayment of debts to the U.S.

U.S. shipping and protect U.S. territory
