This Day in History: The United States Officially Enters World War I

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.
