Answer:
southern legislatures to set blacks aside as a caste separate from whites and subject to special restraints.
Step-by-step explanation:
Black codes were laws that were made in the United States of America by white southerners to control and limit the freedom of black people and also make sure that they will continue to be used for cheap labour after the civil war.
The black Americans were required to sign labour contracts every year and if they refused to sign it, they were forced to do so and wages were withheld from them.
