• Zimmerman Telegram
– From: Arthur Von
Zimmerman To: German
Ambassador in Mexico
• Russian Revolution - if US
entered war they did not
want to support a czar or
king - 1917
• Events and contributing factors that led the U.S. into the
war were
• The United States strong pro-English leanings,
• Wilson's belief in democracy as the most humane and
Christian form of government,
• American investments in Allied countries,
• The interception of the Zimmerman telegram-which revealed
Germany's attempt to bring Mexico into the war on their side,
• Germany's unrestricted submarine warfare, which cost the
United States heavily in lives and goods
• The necessity of keeping the trade doors open for the
economic survival of the United States, and primarily,
• Wilson's fear of a German victory, a victory which would
mean the domination and conquest of countries that would
bring an end to all of Wilson's dreams of peace and
democracy.
Supplying the Allies
• The American entry into the war made an
immediate difference. 
• The United States Navy helped the British find
and destroy German submarines. 
• Convoys–teams–of navy destroyers escorted
groups of merchant ships across the Atlantic,
reducing Allied shipping losses from 900,000 to
300,000 tons a month.
Russian Withdrawal
• In November 1917, the Bolsheviks, a group of
communists, overthrew the democratic Russian
government. 
• Led by Vladimir Lenin, the Bolsheviks wanted to
end Russia’s participation in the war. 
• In March 1918, the Treaty of Brest-Litovsk was
signed with Germany, surrendering territory to the
Germans. 
• The Germans were able to move troops from the
Eastern Front–line of battle–to the Western Front
in France.
German Offensive
• The Germans now launched a powerful offensive
against the Allies, pushing them back to within
50 miles of Paris. 
• It suddenly looked as if Germany might win the
war.
• Although the first American soldiers had
reached France in June 1917, many months
passed before they were ready for battle. 
• When they finally began to fight, the Americans
helped turn the war around.

on the Marne River and then advanced to nearby
Belleau Wood.
• By the middle of July, the Allies had stopped the
German offensive and began an offensive of their
own.
• In mid-September 550,000 American troops defeated
the Germans at Saint Mihiel, east of Verdun.
• Then, American troops joined the Allies in the Battle
of the Argonne Forest (seven weeks)
• In early November, the Allies finally pushed back the

Controlling Public Opinion
• Many Americans were opposed to the war. 
– Some German Americans and Irish Americans
sympathized with the Central Powers.
– Many socialists–people who believe industries
should be publicly owned–and pacifists–people
opposed to the use of violence–opposed the war.
– Some of the strongest antiwar sentiment came
from women’s groups such as the Women’s
Peace Party.
Controlling Public Sentiment
• In 1917 Congress passed the Espionage Act,
which provided stiff penalties for espionage–
spying–as well as for aiding the enemy or
interfering with army recruiting. 
• The Sabotage and the Sedition Acts of 1918
made it a crime to say, print, or write almost
anything perceived as negative about the
government. 
• Such actions would be considered sabotage–
secret action to damage the war effort.
