What can be inferred from the passage of the black codes?

From the passage about the black codes, it can be inferred that after the Civil War, southern states attempted to restrict the rights and freedoms of African Americans through a series of discriminatory laws. These laws aimed to control and regulate the behavior and movement of African Americans, limit their economic opportunities, and maintain white supremacy in the post-slavery South. The passage suggests that the black codes were a means to perpetuate racial discrimination and ensure the continuation of a racially hierarchical society.
