Huffington Post has the article The Confederate General Who Was Erased.
By now, Americans interested in the Confederate monument removal project have had it drilled into them that the monuments were erected decades after the end of the Civil War as testimonies to white supremacy in all its various manifestations: segregation, disenfranchisement, lynching, peonage, and second-class citizenship across the board. But the monuments were not merely commemorative. They were designed to conceal a past that their designers wanted to suppress. That past was the period after Reconstruction and before Jim Crow, years in which African Americans in the former Confederacy exercised political power, ran for public office, published newspapers, marched as militias, ran businesses, organized voluntary associations, built schools and churches: a time, in other words, when they participated as full members of society.
This description of history jibes with my readings of that history. I have read about the progress toward equality that was made after the Civil War and how it was turned back in the early 20th century. This is the history we must remember when having arguments over statues that glorify the Confederate cause.
