After losing the Civil War, Southern states quickly adopted the Black Codes, laws designed to reestablish white supremacy by dictating what the freedmen could and couldn’t do. One common provision barred blacks from possessing firearms. To enforce the gun ban, white men riding in posses began terrorizing black communities. In January 1866, Harper’s Weekly reported that in Mississippi, such groups had “seized every gun and pistol found in the hands of the (so called) freedmen” in parts of the state. The most infamous of these disarmament posses, of course, was the Ku Klux Klan.
