That drop in contra dancing after the Civil War is nicely documented in
"A Short History of Contra" on YouTube here

If you haven't watched that video I strongly (!!!) recommend watching it.
Yes, contra has survived, but it went through several rough patches.
I had lived on a commune (hippy) and, coming back to Atlanta,
found contra dancing something I could make sense of.
(That sentence will make sense after watching the video.)
