96 World War I was a total war, in which the participants channeled all their resources into the war effort. Both sides set up systems to recruit, arm, transport, and supply their armies. Nations imposed universal military conscription, or "the draft." requiring all young men to be ready to fight. Women also played a critical role. As millions of men left to fight, women took over their jobs and kept national economies going.
International law allowed wartime blockades to confiscate contraband, but British blockades kept ships from carrying other supplies, such as food, in and out of Germany. In retaliation, German U-boats torpedoed the British passenger liner Lusitania. Both sides used propaganda to control public opinion, circulating tales of atrocities, some true and others completely made up.
As time passed, war fatigue set in. Long casualty lists, food shortages, and the failure to win led to calls for peace. The morale of both troops and civilians plunged. In Russia, stories of incompetent generals and corruption eroded public confidence and led to revolution.
Until 1917, the United States had been neutral, but in that year it declared war on Germany. Many factors contributed to this decision, including Germany's unrestricted submarine warfare.

A final showdown on the Western Front began in March 1918. With American troops, the Allies drove back German forces. In September, German generals told the kaiser that the wat could not be won.
