that is a recent development. from the late 1860s to the 1960s, most civil war history was written by Southern authors. Their works are collectively referred to as the “Lost Cause”.

I have no idea if that's true because I have never made any effort to tabulate who wrote what and where they were from.

But aside from that, an interesting question would be, "Where was all this stuff published?"
