Georgia Performance Standards
 SS5H4 The student will describe U.S. involvement in
World War I and post-World War I America.
 a. Explain how German attacks on U.S. shipping during the
war in Europe (1914-1917) ultimately led the U.S. to join the
fight against Germany; include the sinking of the
Lusitania and concerns over safety of U.S. ships, U.S.
contributions to the war, and the impact of the Treaty
of Versailles in 1919.
 b. Describe the cultural developments and individual
contributions in the 1920s of the Jazz Age (Louis
Armstrong), the Harlem Renaissance (Langston Hughes),
baseball (Babe Ruth), the automobile (Henry Ford), and
the airplane (Charles Lindbergh).
World War I
 Nationalism
 Militarism
 Alliance
 Trench warfare
Hint: Remember “alliance”
for ALIKE. People become
partners because they are
alike in some way
(ALLIANCE). Add to word
wall.
A synonym of
“alliance” is
partnership.
When people
form alliances,
they become
partners.
With a partner,
compare and
contrast
nationalism and
militarism.
SO…Europe Goes to War!
World
War I has
begun!
 Let’s organize this information:
 Many European countries believe in militarism, so
ALIKE countries form alliances.
2 Biggest Alliances
 Allied Powers (Allies)
Serbia, Russia,
Belgium, and France
 Central Powers
Austria-Hungary, Germany
 Cause: Serbian assassinated Archduke
Ferdinand (Archduke=Austria-Hungary) Effect:
Austria-Hungary declared war on Serbia (Russia
steps in to help Serbia; Germany steps in to help
Austria-Hungary…
 and also declares war on Belgium and France!
World War I Has
Begun!
 Soon all of Europe was at war!
 Germany and Austria-Hungary …Which side?
 Central Powers
 Russia, Great Britain, and France were allies and

became the leaders of an alliance known as…
The Triple Entente
The conflict eventually involved nations around the
world.
Was now called WORLD WAR I
Partners: Tell why it was known as WWI.

World War I
 At first, most US citizens wanted to stay out of
the war.
 They believed it was Europe’s fight, not theirs.
Do you remember what this is called???
 ISOLATIONISM!
 President Woodrow Wilson won re-election in
1916 vowing not to get the US involved in
the fighting.
 But…over time, a number of things happened
that led the United States to enter the war…
LESSON 2
U-Boats and the Lusitania
 During WWI, Germany used U-boats.
 U-boats were submarines (ships that sail under
water).
 Could stay hidden beneath the surface of the water
as they fired torpedoes that sank ships
 German U-boats fired not only on enemy ships but
also on ships from other countries
 Germany believed these ships were actually carrying
goods meant to help the nations it was fighting.
Here’s the problem…
U-Boats and the Lusitania
 Some of these ships carried US citizens!
 In May of 1915, German submarines sank a
passenger ship called the Lusitania.
 Over 100 US passengers died!
German
submarines

Lusitania.

People in
the U.S.
were
FURIOUS!
U-Boats and the Lusitania
 In reality, the US government was secretly


using the Lusitania and other passenger
ships to sneak military supplies to Great
Britain and its allies.
To most people, however, Germany’s actions looked
like an evil attack against innocent civilians.
Public opinion started to change.
More people in the US begin to favor war.
What is your opinion? Do you think
Germany had a right to sink the Lusitania?
Discuss this with a neighbor.
The Most Destructive War in History At
That Time
 Because of these new technologies: submarines,
airplanes, mustard gas, armored tanks, hand
granades, etc. this was a highly destructive war!
 A concept called Trench Warfare was developed.

Lesson 3
Other Key Vocabulary
•Rations
•Propaganda
•Armistice
•Isolationism
An island is
isolated…so
isolationism
means far
away, from
other lands.
Problem:
Soldiers needed
supplies to fight
in the war.
Solution:
Businesses and
workers worked
hard together to
make supplies
for the soldiers.
What does this have to do
with economics? Turn to a
neighbor and explain how
this would affect supply
and demand during this
time period.

SUMMARIZER: With a
partner, discuss the
concepts of nationalism,
militarism, imperialism,
and isolationism.
The Roaring Twenties
 Building an army to fight in World War I meant that
the nation needed weapons and supplies. Such
production created jobs and high demand for
products. As production and jobs increased, so did
prosperity. After the war ended, most citizens just
wanted to return to normal and enjoy the new
wealth. The decade that followed the war became
known as the Roaring Twenties.
The Jazz Age
 The first years of the 1920s were called the Jazz Age.
Jazz was a new form of music that made its way from
New Orleans to northern cities early in the decade.
African American musicians created it. It is a style of
music in which performers use brass, woodwinds,
and percussion instruments to improvise (play
without looking at notes) rather that rely on sheet
music. The fast and spirited beat of jazz made it
popular with both blacks and whites. Jazz led to the
creation of several new dances in the 1920s.
Trumpeter Louis Armstrong became one of the most
famous jazz musicians in history during this period.
The Harlem Renaissance
 Another important movement among the African
American community was the Harlem Renaissance.
It involved black writers and artists. It was named
for Harlem, New York, the mostly black community
where it began. Langston Hughes became famous for
his poems and stories of black life in America.
Henry Ford and the Automobile
 Early in the twentieth century, only a few people
owned automobiles. Only the rich could afford to buy
them. Then, a man named Henry Ford introduced
the idea of mass producing cars. He wanted to make
so many cars that he could afford to sell them
cheaper and still make a profit. This would make
Ford a lot of money and make it possible for
common people to own an automobile. Ford
introduced a new kind of assembly line.
Henry Ford and the Automobile
 An assembly line allows workers to focus on one task
rather than trying to assemble the whole product.
Each of Ford’s workers was responsible for
assembling one part of each car. Earlier assembly
lines required workers to walk from station to
station. Ford’s brought the parts to the workers. His
employees could stand in one spot while the parts
came to them. This made the work much faster and
increased production. Ford paid his employees $5 a
day (a good salary back then) so that they could
afford to buy his cars.
Henry Ford and the Automobile
 Henry Ford’s first mass-produced car was known as
the Model T. It revolutionized the auto industry.
Ford’s ideas about mass production and his assembly
line helped make other businesses better as well.
American Heroes
 American heroes arose during the 1920s. One of the
most popular was Babe Ruth. Ruth was a great
baseball player. He played most of his career with the
New York Yankees. Ruth became famous for his
powerful hitting. Before he left the game, he became
the all-time home run leader. His 714 homeruns
stood as a record until 1974, when Atlanta Brave
named Hank Aaron finally broke it. Babe Ruth still
rank third on the all-time homerun leaders list.
American Heroes
 Charles Lindbergh also became a hero during this
period. Lindbergh became the first person in history
to fly a solo flight non-stop across the Atlantic
Ocean. He flew from the United States to Paris,
France, in 1927. Today, Lindbergh’s plane hangs
from the ceiling of the National Air and Space
Museum in Washington, D.C.
Other Important People
 Duke Ellington
 Margaret Mitchell
 Jesse Owens
