Explanation:

The Black Codes were a series of laws that were passed after the Civil War. These laws were generally passed in the South, and their main objective was to restrict the freedom of the recently freed black population. These laws restricted the places where freedmen could go, prevented them from accessing some employment and forced them to work for low wages. These laws made it difficult for African Americans to fully exercise their civil and political rights.
