Congress has declared the existing governments of the South illegal, and divided the South into 5 military districts, each one with a general in charge. The military will rule a district until the district ratifies the Fourteenth Ammendment, repeals their black codes, and gives African Americans equal rights. Some states, like Texas, will even have to ratify the Fifthteenth Ammedment, which allows African Americans the right to vote. Congress also required many white Southerners to take the Ironclad Oath if they wanted to vote, take office, or serve on juries. The Ironclad Oath states that you have not previously aided the Confederacy, and because many white Southerners had, they could not be granted those rights.
Freedmen get the vote!
Freedmen exercising their right to vote at the polls
Freedmen are being helped to register to vote by General Griffin's army, the Freedmen's Bureau, and other freedmen. So far, by 1886, 50,000 freedmen have already been registered to vote. Unfortunately, the KKK (Ku Klux Klan) have come along. The KKK is a large group of racist white adults who want to stop freedmen from exercising their rights, including the right to vote. The KKK opposes carpetbaggers (Northerners who came to the South to help reconstruct) because they are coming to interfere with the KKK's plan and the oppose scalawags (white Southerners who support reconstruction) because they are supposedly "traitors."
The KKK has recently attacked a school belonging to the Freedmen's Bureau in North Texas to protest black voting rights (and other rights). Dozens killed, families devastated. May their souls rest peacefully.
