Here’s Professor William Cooper of LSU giving a class lecture on the role of “honor” in Antebellum Southern culture. It’s a pretty good lecture, and near the end he begins the linkage of this concept to secession and the war.
The video’s description reads, “This week, Professor William Cooper examines the idea of honor in the Antebellum South. Professor Cooper explains how a person’s “honor” was significantly defined by public perception. And for a gentleman, any perceived slight of a person’s honor demanded defense, usually through a duel. This hour long class took place at Louisiana State University.”
