Which laws enacted immediately after the civil war were designed to maintain the social structure of slavery?

A series of laws called the Black Codes were enacted after the Civil War to maintain a social structure of slavery.

Explanation:

Black Codes were passed in the southern states to keep the now free African Americans in a social condition similar to slavery.  This meant that they could not participate in politics or rise up high on the economic scale.  The laws varied from state to state, being more rigid in some places and granting a bit more freedom in others.  White supremacist groups made sure to continue oppression of blacks to ensure their control of land, resources, and power.  For many African Americans, the black codes meant their lives remained pretty much the same as when they were slaves.

These laws set the precedent for the Jim Crow laws that would be enacted in the future.
