Step-by-step explanation:
After the Civil War, southern governments enacted legislation known as Black Codes to restrict the rights of freedmen. These laws granted some rights to African Americans, such as the right to own property and make contracts, but they also imposed severe restrictions. Freedmen were denied the right to serve on juries or in state militias, and their testimony against white people was not recognized. Vagrancy laws were used to arrest and fine freedmen who couldn't prove means of employment, effectively reasserting control over their labor.
