At the end of the 19th century, two American families along the West Virginia/Kentucky border, the Hatfields and the McCoys, engaged in a now infamous feud. Twelve members of the families were killed in various instances of violence along with a few bounty hunters. It got to the point where the original source of the feud (an ownership dispute over a pig) didn’t matter. Instead, what mattered was that Hatfields killed McCoys, and McCoys killed Hatfields.
