Answer:
The Ku Klux Klan was a domestic terrorist organization to maintain white supermacy. They used intimidation, violence and murder in the Southern governments.
The Southern states were known as the Confederacy, which broke away from the Union to protect their right to own black people as slaves. The Union won, and the 11 Southern states became part of the United States again. Enslaved African Americans were freed.
However, they used tactics to target the newly freed African Americans. Their whole purpose was to have white people control in the South and have advantages in government and society.
Black people suffered intimidation and violence and couldn't have the right to vote.
