Woodrow Wilson advocated for neutrality and honesty in international affairs as tensions rose in Europe prior to WWI. The main causes of the war included militarism, alliances, imperialism, and nationalism. The assassination of Archduke Franz Ferdinand of Austria-Hungary by a Serbian nationalist triggered Austria-Hungary's declaration of war on Serbia and aligned nations, starting WWI. While the US initially remained neutral, events like the sinking of the Lusitania and revelations in the Zimmerman Telegram turned American public opinion against Germany and led to the US entering the war in 1917 on the side of the Allies.

1. Chapter 14 WWI
Woodrow Wilson was the President
He stated to “strike a new note in international
affairs and to see that sheer honesty and even
unselfishness should prevail over nationalistic self-
seeking”.
He strongly opposed imperialism

2. What was happening in Europe?
• Despite more than 40 years of general
peace, tensions among some European
nations—England, France and
Germany—were building in 1914.
Throughout the late 1880’s and early
1900’s, a number of factors created
problems among the powers of Europe
and set the stage for a monumental war.

3. The MAIN reasons for war

4. Militarism
• Building up arms
• When Germany stated to modernize its army
and navy, England felt it had to do the same .
Other major powers followed their lead.

6. Alliances
• Agreements or promises to defend and
help another country.
• A series of interlocking allies
• When the conflict started, these ties led
to the division of Europe into 2 camps

8. Imperialism
Trying to build up an empire. By the 1800’s,
Britain and France had colonies in Africa
and Asia that provided raw materials and
markets for their products. Germany
wanted its own colonies and trade

10. Nationalism
• Having pride in your
country, willing to defend it. As
well as self-determination-the
ability to chose own government

11. The Balkan Crisis

12. • Historically, the Ottoman Empire and the
Austro-Hungarian Empire had ruled the
Balkans. But as nationalism became a
powerful force in the 1800’s, the different
national groups—the Serbs, Bosnians, Croats
and Slovens-- within these empires began to
press for independence.
• The first to gain independence were the
Serbs—they formed Serbia.

14. Russia supported Serbia, BUT Austria-
Hungary did not and annexed Bosnia

15. The Serbs were furious-it
demonstrated to them that Austria-
Hungary had no intention of letting the
Slavic people become independent.
• So then the archduke of Austria-Hungary
Franz Ferdinand visited the Bosnia capital of
Sarajevo and was assassinated by a Serbian.

16. The War Begins

17. The War Begins
• The Austria-Hungary government blamed
Serbia so they were going to attack Serbia.
• AuHu asked Germany for support
• AuHu declared on Serbia
• Germany declared war on Russia and France
• After Germany crossed through Belgium to
France, Britain declared war on German

18. The Sides
Triple Entente-Allied Powers Triple Alliance—Central Powers
--Germany
--Great Britain --Austria-Hungary
--France --Italy
--Russia
(United States)

19. American Neutrality
• When the fighting began, President Wilson
declared the US to be neutral. However, that
was difficult to do.
• Why????

20. • We were a country of immigrants—different
opinions.
• There were over 8 million Germans living here
and over 4.5 million Irish.
• Most Americans did side with the Allied
Powers.
• Propaganda played a very important role.
Both sides used propaganda to influence the
US to enter on either side.

25. Although most supported the Allies
and hoped for their victory, a series
of events gradually eroded
American neutrality and drew the
nation in to the war firmly on the
side of the Allies.

26. Unrestricted Submarine Warfare
• Shortly after the war began, the British
deployed their navy to blockade Germany and
keep it from obtaining supplies, as well as
plant mines in the North Sea.

27. • Germany countered that action
by deploying its newest vehicle in
their navy—the U Boats-short for
Unterseeboot—meaning
“underwater boat”. They
announced that they would
attempt to sink without warning
any ship they found in the water
around Britain.

28. Lusitania
• On May 7, 1915, despite warnings from
Germany, the British passenger liner Lusitania
entered the war zone. A submerged German
submarine fired on the ship, killing nearly
1,200 passengers including 128 Americans.
Americans were outraged.

30. • President Wilson remained neutral. He sent a
diplomatic team to Germany to negotiate
terms of unrestricted submarine warfare. The
next year Wilson’s policy was tested when
another u boat torpedoed the French
passenger ship the Sussex. Americans were
injured on board. He sent another tam of
diplomats to Germany and stated that if
Germany does not stop sinking passenger
ships, the US would enter the war. Germany
agreed to stop

31. Four years come and four years
go—another election.
“He kept us out of war”
Wilson is re-elected

32. Zimmerman Letter
• British intelligence intercepted a telegram from a
German official to the German ambassador in
Mexico. In it Zimmerman urges Mexico to declare
war on the YS and Germany will help it regain lost
territory in Texas, New Mexico and Arizona.
Americans were furious with Germany. Then in
1917, Germany resumed unrestricted submarine
warfare, sinking 6 American merchant ships
without warning.
• In 1917 Wilson asks Congress to declare war.
