The Legislature passed "Black codes" that restricted free slave rights.
Step-by-step explanation:
Black codes are laws that are designed to limit the freedom of African Americans. During civil war, this black code was implemented on African Americans to work for low wages.
Southern states framed black codes or black laws during 1865 and 1866. The black laws were passed after the American Civil War.
After the constitution of 1866, the freedom of African Americans was restricted. To help the former slaves an organization called “Freedmen's Bureau” was created.
