Civil Rationing
Rationing was first introduced into the war on the side of the Allies. The unrestricted warfare of the Germans caused the British to force their people to eat less. One of the main staples in the diet of the British is bread. The rationing propaganda poster was used to help people understand and sympathize with the government's efforts to curtail food intake. The restrictions introduced by Defense of the Realm Act failed and the government then tried to introduce a voluntary code of rationing whereby people limited themselves to what they should eat. The standard was set by the Royal Family. However, this did not work. Those who worked in the munitions factories did not have enough food while anyone with money could get more than enough food on the black market. Any area that could grow food was converted to do so - gardens were turned into allotments and chickens etc. were kept in back gardens.
Propaganda
Propaganda is the government's way of reinforcing and introducing ideas into the minds of the public. As opposed to impartially providing information, propaganda, in its most basic sense, presents information primarily to influence an audience. Propaganda often presents facts selectively (thus possibly lying by omission) to encourage a particular synthesis, or uses loaded messages to produce an emotional rather than rational response to the information presented. The desired result is a change of the attitude toward the subject in the target audience to further a political or religious agenda. Propaganda can be used as a form of political warfare. This warfare commenced by the government was internal and easily controlled. Thus, it was often used as a means of mass manipulation. It proved so effective that it would continue for all wars to come.
