Final answer:
African-Americans in the South were expected to follow specific rules and regulations called Black Codes, which aimed to control their behavior and maintain white supremacy. These codes granted some rights to African-Americans but denied them other fundamental rights. This limited their mobility and forced them into exploitative labor contracts.
Step-by-step explanation:
African-Americans were expected to behave in a certain way in the South during this time due to the establishment of Black Codes, which were laws aimed at controlling black behavior and maintaining white dominance.
These codes granted some rights to African Americans, such as the right to own property and make contracts, but stripped away many fundamental rights. They were denied the right to serve on juries or in state militias, their testimonies against white people were not recognized, and severe vagrancy laws were enforced.
These unwritten rules limited the mobility of African-Americans, criminalized their leisure, and forced them into exploitative farming contracts. This effectively maintained a system of control and dominance over black labor.
