This Day in History: The United States
Officially Enters World War I April 6, 1917 War against Germany was
declared in both the Senate and
House of Representatives by votes
of 82-6 and 373-50, respectively.
President Woodrow Wilson
had called for the declaration
of war four days earlier.
The U.S. had been preparing
for war since the passage of a
$250 million arms appropriations bill in Feb.
Though initially against joining
the war in Europe, American public
opinion shifted as German attacks
on ocean liners escalated.
The first U.S. troops landed
in France in late June.
The arrival of fresh and well-supplied
forces proved to be a turning point in
the war after four years of bloody combat.
