The correct answer to this open question is the following.
As there are no options attached to this question, we can assume that the Black Codes and Jim Crow laws were born as a result of both slavery and racist policies to restrict the rights of black Americans after the Civil War.
After the Civil War and as part of the Reconstruction, radical Republicans approved the passing of the 15th Amendment to the United States Constitution that granted political and civil rights to African Americans. But the southern states did agree at all with that decision and established the Black Codes to limit the rights of black people. Later, the Jim Crow laws were a series of legislations that authorized racial segregation in southern states. This produced many confrontations between blacks and whites.
