Final answer:
The black codes from the perspective of white southerners aimed to maintain racial slavery's social and economic structure and uphold white supremacy. They restricted the civic participation of freed enslaved people and limited their rights and social mobility.
Step-by-step explanation:
The stated purposes and goals of the black codes from the perspective of white southerners were to maintain the social and economic structure of racial slavery in the absence of slavery itself and to uphold white supremacy. These laws aimed to restrict the civic participation of freed enslaved people by depriving them of rights such as voting, serving on juries, owning or carrying weapons, and renting or leasing land. The black codes essentially aimed to perpetuate control over black labor and limit the social mobility of African Americans.
