One of the best ways to inspire the oppressed to action is through slogans. That way, they can get an idea of what they're fighting for.
This is page has a list of slogans from the Soviet Union celebrating the 60th anniversity of the October Revolution of 1917. I don't have any from China or Cuba, but if I get some I will add them to this list. To see the whole list of Soviet slogans, please visit the 73 Slogans of the Soviet Union website.
