the answer is religion
In the Civil War time period, the Ku Klux Klan could be considered a unifying and dis-unifying force. If you think about it, it was unifying because it brought strong radicals of the south ( the southern democrats) together to try and pass their beliefs and show they did not want to be part of the union again, and show that they do indeed hate blacks or any other minority for that matter and were willing to do whatever it took (even murder) to get that point across. These acts were quite disruptive; they broke the law, committed heinous crimes, I'm sure without even explaining you know what they were notorious for. So yeah, if it comes down to it the KKK could be considered in most cases a unifying and dis-unifying force.
