Whether or not this war progressed the country or not is debatable, and depends on what you prioritize. The south economy was completely devastated and the north still saw a small inflation. 1000's of Americans died, considering that it was American on American. A president was assassinated. The only good that came out of this was that the slaves were freed. But still, they were nowhere near equal. So in my opinion, not, the Civil War did not show progress in history.
