Hello!
First, I would review what the freedmen and the black codes are.
Freedmen - The freedmen are the group of slaves that were released from their previous masters, the freed slaves.
Black Codes - The black codes were a set of rules that applied to black people, passed back in the slave era. They included rules that restricted the ownership of property, relationships with white women, etc.
These therefore impacted the lives of the freedmen, as it restricted their actions.
The rules caused them to have to watch what they were doing in public spaces, or else there would be bad consequences (If you want to further look into the bad consequences, the story of Emmett Till is an example)
Hope this helped!
