America Joins World War I

A huge war had been raging in Europe for almost three years when America decided to help.

President Woodrow Wilson said America must fight to 'make the world safe for democracy.'

Millions of young men signed up, called themselves 'doughboys,' and boarded ships for France.

There was a cheerful song called 'Over There' that everyone sang as the soldiers left home.

American help gave the tired Allies the boost they needed to end the war a year and a half later.
