3. World War I The Great War
Begins in Europe in 1914; United States enters in 1917
Nearly 50 million die as a result of war
Ends with Treaty of Versailles in 1919
Devastation changes U.S. view of itself and world
BACKGROUND INFORMATION:
The war was fought between two groups: the Central Powers (Germany, Austria-Hungary, Bulgaria, and Turkey) and the Allies (France, Great Britain, Russia, Italy, Japan, and the United States).
The Russians withdrew from the war in 1918 after the Bolshevik revolution.
More than 500,000 soldiers died in 10 months in a battle near the town of Verdun in France.

4. World War I Trench Warfare
Armies fought from trenches, or deep ditches
Cold, wet, and dirty conditions
Disease spread rapidly
No-man’s-land—area between trenches— strewn with barb wire and land mines
BACKGROUND INFORMATION:
Trenches might be simple holes or complex networks with rooms for sleeping and eating. Trenches along the Western Front stretched for more than 400 miles, from the North Sea to the border of Switzerland.
Battles began with massive artillery barrages. Then, soldiers went “over the top” of the trenches and charged across no-man’s-land toward the enemy’s trenches. As they ran, thousands were cut down by a hail of machine-gun fire.

5. World War I New Weapons Poison gas Airplanes Machine guns Submarines
Tanks
BACKGROUND INFORMATION:
Machine guns could fire 400 to 600 rounds of ammunition per minute. Huge guns launched artillery shells—some of which contained poison gas.
Both sides used poison gas—chlorine gas and mustard gas. Poison gas destroyed soldier’s lungs, killing them slowly. Soldiers used gas masks to protect themselves from the poison gas.
Allied and Central Powers used airplanes mainly to gather information. As the war went on, both sides installed machine guns on fighter planes and shot down enemy scouts. Later, both sides built large bombers and developed planes that could take off from ships.
Germany used its U-boats, or submarines, to sink Allied ships.
British and French forces developed armored tanks to support infantry attacks on trenches.
