Step-by-step explanation:
The laws passed by the new southern governments that attempted to regulate the lives of former slaves were known as the Black Codes. These codes were enacted in most southern states in 1865-1866 and were based on the Slave Codes that were in effect before emancipation. The Black Codes aimed to maintain the social and economic structure of racial slavery by restricting the civic participation of freed enslaved people, depriving them of rights such as voting, serving on juries, owning or carrying weapons, and renting or leasing land.
