Propaganda is information used to promote a point of view or political cause.
The word first took this meaning in the first world war. In those days, it was a neutral term. It referred to information that was generally helpful with no political objective. These days the word has negative connotations.
Propaganda is usually seen as information that presents only one side of an issue, thus promoting a biased view of a situation.
Propaganda is especially popular for governments during war time. During the second world war, in particular, there were some very famous examples of propaganda posters. They encouraged citizens to sacrifice themselves for their countries and distrust people from other countries.
