In his memoirs, Albert Parsons describes his experiences after the Civil War, which included accepting the end of slavery, supporting the Reconstruction amendments, and opposing the Ku Klux Klan. While only a minority of former Confederates took this path, Parsons mentions Robert E. Lee’s subordinate General James Longstreet as the most prominent of the Reconstructed Confederates.
Here is the relevent section of the Parsons memoir:
The deeper I delve into the sources, the more the popular tropes about the War and postwar era are shown to be false. Men like Parsons belie the stereotypes, and while there were plenty of racists in the Reconstruction South, so too were they numerous in the North. The fact that Parsons not only supported racial harmony but toiled for worker’s rights demonstrates how forward thinking he truly was. Thank you for illuminating this chapter of postwar America for me.
