Describe the black codes in a short paragraph. What was their purpose and effects?

Black Codes were a series of restrictive laws passed after the American Civil War between 1865 and 1866. These laws were in the South. The purpose of the Black Codes were to further suppress African Americans. They governed the conduct of African Americans and placed a lot of limitations on them. They were passed in the South because they were upset that after the Civil War had ended and slaves were freed they lost their free labor.
