Governments and other political institutions employ propaganda to sway public opinion, instill ideas, and exert a degree of control over people.

So what exactly constitutes propaganda and how does it work? Does it always involve lies or falsehoods? Can propaganda ever be morally justified or is it a pernicious form of communication?
