How Was Propaganda Used In The First World War???

Propaganda was used mostly by images. These images were shown to make their allies or other countries around the world feel bad or angry about what’s happening, or to influence someone to do something. For an example, in class we learnt about this photo that the German soldiers were escorting the Belgium civilians somewhere. No-one knows if the soldiers were helping or just taking them to a camp to set them in jail/execute them. But what we do know is that this photo made Brittan influenced to help them and that resulted in millions of deaths. So all this time, the German soldiers were probably trying to escort the Civilians somewhere so they can be safe and not in the gunfire and Brittan just started war with them for no reason, or Brittan started war for a good reason to save the people of Belgium and to bring the German people to a halt and stop their evil across the globe. Propaganda could of been used for anything. For all we knew the whole ‘war’ could of been a setup. For all we know, the president of Austria-Hungary and his wife didn’t get shot as this COULD of been used just to trigger a war between many peaceful nations.
