The memory of the war in the white South crystallized in the myth of the "Lost Cause": that the Confederate cause was just and heroic. The myth shaped regional identity and race relations for generations.
Alan T. Nolan notes that the Lost Cause was expressly a rationalization, a cover-up to vindicate the name and fame of those in rebellion. Some claims revolve around the insignificance of slavery as a cause; some appeals highlight cultural differences between North and South; the military conflict by Confederate actors is idealized; in any case, secession was said to be lawful.
