The document discusses how propaganda was used during WWI on the homefront. Propaganda was used for four main reasons: to encourage men to enlist in the armed forces, to encourage people to conserve resources on the homefront, to encourage any contribution to the war effort, and to make people hate the Germans. Propaganda posters and other media used both positive messages to encourage support and negative messages playing on fears. The two main styles were positive propaganda appealing to patriotism and helping win the war, and negative propaganda portraying the enemy as a threat.
