Final answer:
The statement is false; laws following Nat Turner's Rebellion restricted the rights of free blacks but did not require them to stay in Mississippi. Some laws even required free blacks to leave certain states.
Step-by-step explanation:
The statement that "After Nat Turner's slave revolt the law required free blacks to stay in Mississippi" is False. Laws reacting to Nat Turner's Rebellion in 1831 restricted the rights of free blacks across the southern states, including Mississippi, but these laws did not require free blacks to stay in any particular state. Instead, the laws imposed more stringent controls and limited movement, assembly, and education among other rights. In fact, some laws in places like Virginia required free blacks to leave the state.
