I see that Acton Media has a film coming out this month that looks like it addresses some important issues and provides some useful historical context. See The Birth of Freedom - A Documentary on the History of Freedom for more information, to view the trailer, or to arrange a screening. (Warning: the trailer includes images of torture and war dead and other nasty stuff. It's in context, but it might not be suitable for children.)
The official website also has a useful list of primary documents and websites, information on important people, and relevant court cases.
hat tip: Acton Institute
Update: The film is just shy of an hour long, if that makes any difference to you if you're hoping to set up a screening.
