In the beginning of this week, we’re going to explore how the US moves closer and closer to Civil War. We talked earlier about how the Mexican War leads us into the Civil War, as well as Uncle Tom’s Cabin, the Kansas-Nebraska Act and the Dred Scott Case. Each plays its own role. Now, we’re going to look at the issues through the story of a History Channel documentary called America: The Story of Us. Here are three of our first assignments.
