This illustrates something that even a lot of liberals don’t always get. Most of these monuments were not erected right after the Civil War. In fact, all the way to 1890 there were very few statues or monuments dedicated to Confederate leaders. Most of them were built much later. And since I’m not an academic, I feel comfortable squeezing this history into a very short, oversimplified summary:
1861-1865: Civil War.
1865-1875: Reconstruction Era.
1875-1895: Reconstruction Era ends. Blacks are steadily disenfranchised, allowing Southern whites to enact Jim Crow laws. In 1896, Jim Crow is cemented into place when the Supreme Court rules it constitutional.
1895-1915: With blacks disenfranchised and Jim Crow laws safely in place, Southern whites begin a campaign of terror against blacks. Lynchings skyrocket, the KKK becomes resurgent, and whites begin building Confederate statues and monuments in large numbers.
