The American Civil War is viewed as the most significant event in the country’s history. But why did the United States and the Confederate States go to war? In this talk we will explore why and how the American Civil war was fought. Along the way we will visit Bull Run, Gettysburg and Antietam (illustrated with photographs I have taken on my visits to these battlefields), meet Abraham Lincoln, Jefferson Davies and Robert E. Lee and learn how the war produced the United States we know today.
