Moving Toward War (cont.)
What events led to the United States
declaring war against Germany?
Moving Toward War (cont.)
The British navy blockaded Germany to keep it from
getting supplies. To get around the blockade, Germany
deployed U-boats. The Lusitania, a British passenger
liner, was hit by the Germans, killing almost 1,200
passengers including 128 Americans. A German official,
Arthur Zimmermann, cabled the German ambassador in
Mexico, proposing that Mexico ally itself with Germany. In
return, Mexico would regain territory it had earlier lost to
the United States. The Zimmermann telegram was
intercepted by British intelligence and leaked to American
newspapers. In February 1917, Germany went back to
unrestricted submarine warfare and, soon after, sank six
American merchant ships. On April 6, 1917, the
United States declared war against Germany.
