Wiki: The New Orleans massacre of 1866 occurred on July 30, when a peaceful demonstration of mostly Black Freedmen was set upon by a mob of white rioters, many of whom had been soldiers of the recently defeated Confederate States of America, leading to a full-scale massacre.[4] The violence erupted outside the Mechanics Institute, site of a reconvened Louisiana Constitutional Convention.[5] According to the official report, a total of 38 were killed and 146 wounded, of whom 34 dead and 119 wounded were Black Freedmen. Unofficial estimates were higher.[6] Gilles Vandal estimated 40 to 50 Black Americans were killed and more than 150 Black Americans wounded.[7] Others have claimed nearly 200 were killed.[2] In addition, three white convention attendees were killed, as was one white protester.[8]
Tangentially, why the fuck were confederates allowed to keep their political offices? The mayor at the time was a reinstated pro-confederacy Democrat. Unhung traitors truly are the death of a republic.
