Which is a good organizing topic for the post–civil war era?

A topic for the Civil War era would have to be "Reconstruction." Reconstruction is the reestablishment of the seceded states in the Union after the American Civil War. So in this case it would be a good topic to go over since how it help rebuild states in the Union after the war ended.

Hope this helps!

Ithink a. cause egyptians worship a status and i havent even heard of c in my life.
