None of the above.

To understand the policies of the Black Codes and what they did, one would need to research the historical context during the Reconstruction era following the American Civil War. Here's a step-by-step guide on how to find information on the subject:

1. Start by consulting credible sources such as history textbooks, academic journals, or reputable websites. Sources that specialize in American history or the Reconstruction era are particularly useful.

2. Search for keywords related to the topic, such as "Black Codes," "Reconstruction era," or "policies after the Civil War." This will help you narrow down your search and find relevant information.

3. Look for sources that provide an overview of the Black Codes. These sources should explain what the Black Codes were, who implemented them, and why they were enacted.

4. Read about the specific provisions of the Black Codes. Black Codes were a series of laws enacted by southern states after the Civil War with the intention of restricting the freedom and rights of newly freed African Americans. The provisions of the Black Codes varied from state to state but generally included elements such as labor contracts, restrictions on movement and occupation, and limitations on accessing education and political rights.

5. Analyze the impact of the Black Codes. After understanding the policies, it's important to explore their consequences. The Black Codes were seen as an attempt to reintroduce elements of slavery and maintain white control over the newly freed African Americans. They severely limited the rights and opportunities of African Americans, perpetuating racial discrimination and inequality.

By following these steps and conducting thorough research, you should be able to gain a comprehensive understanding of what the policies of the Black Codes did. Remember to critically evaluate your sources to ensure accuracy and objectivity.
