How is propaganda used in Animal Farm?

Propaganda
is satirized throughthe pig. He symbolizes Stalin and the government's control over all media
and information being given to the peasants. Because they were uneducated, the peasants could
not follow twisted or illogical arguments when they were presented  by someone whom they
respected and considered intelligent.  Furthermore, just like in Soviet Russia, the people had
once trusted the government's intentions, so they trust the pigs and Squealer, and don't want to
seem ungrateful or confrontation by questioning things that confuse them (especially because
they know they don't have to the ability to argue back).
