I have been listening to this course on my iPhone and I have enjoyed it so much that I decided to recommend it.
The course is about the Civil War. There are themes that are relevant to today’s political discussions such as federalism, the impact of supreme court cases on politics, and impeachment. The professor is a wonderful teacher. I was very engaged in this course because the professor did such a good job of making the material meaningful using words. These are great audio files if you want to learn about the Civil War and its impact.
