What many people do not realize is that these statues aren't Civil War memorials, they are in reality, monuments of white supremacy ...
Reconstruction is generally dated from 1865 to 1877 when the federal government withdrew federal troops and allowed the restoration of so-called ‘home rule’ in the South. But black political power and biracial political coalitions didn’t disappear overnight. Though the sheet anchor protecting black citizenship was withdrawn, it took the better part of a generation for what we now recognize as the Jim Crow system to be firmly entrenched throughout the South. To note but one example, the judicial cornerstone of Jim Crow, ‘separate but equal’, only became the law of the land with Plessy v Ferguson in 1896.
That statuary which is only beginning to come down in our day dates largely from this era and constituted a celebration and affirmation of this victory. Not the victory of the Civil War, which was of course a defeat but the sectional victory to define the post-war settlement.
Consider some dates: Lee Circle in New Orleans, 1884; Lee Statue on Monument Avenue, Richmond, Virginia, 1890; Robert E. Lee Monument (Marianna, Arkansas), 1910; the Robert Edward Lee sculpture in Emancipation Park, Charlottesville, Virginia, commissioned 1917, erected 1924. All of these statues date not from the Civil War Era but from the decades of the establishment of Jim Crow, to celebrate the South’s ability to establish an apartheid system on the ruins of the Antebellum slave South. A statue of Lee in uniform, mounted on a horse in a southern town square has only ever had one meaning: white supremacy. These statues didn’t come to be associated with racism and Jim Crow only after the Civil War had receded into memory. They were created, from the start, to mark and celebrate the foundations of Jim Crow, uncontested white rule. More mythically, but to the same end, they were built to glorify a vision of the South in which her black citizens had no place.
