Finally, the moment you have been waiting for . . .

The United States enters World War I

Reminders:

• WWI began in 1914.
• The two sides were
  • Central Powers: Germany and Austria- Hungary
  • Allies: France, Great Britain, and Russia
• Russia dropped out because Czar Nicholas and his entire family were murdered.
• The war has waged for 3 years with no clear winner.

The four pictures you see represent the four most well-known causes that the United States got involved in WWI.  It is important to remember that from 1914 when the war broke out until 1917 the United States was considered isolationist.  (That means the U.S. tried to isolate itself and stay away from the fighting nations to avoid conflict.)  Isolationism didn’t work for long.  By 1917 the U.S. was fighting in WWI.
