Origins and Ideologies of the American Revolution
This is one of the Great Courses which are usually very good. Once in a while you will get a boring Professor but most of the time these are excellent.
I have four degrees but still have a thirst for knowledge and it helps me with the FunTrivia games once in a while.
These Great Courses come in various forms-- online, video, and audio.
This is also a good one--
American Civil War | The Great Courses
And this looks very interesting--
The Great Debate: Advocates and Opponents of the American Constitution | The Great Courses
I slugged my way through this one--
Great Minds of the Western Intellectual Tradition, 3rd Edition Prof. Kors-Philosophy & Intellectual History
Some of the local libraries have some of these as well as older The Great Courses offerings.
