Final answer:
True, in reaction to Nat Turner's Rebellion, southern states passed legislation that reinforced slavery and curtailed the freedoms of slaves and free blacks, including prohibiting education and regulating religious meetings.
Step-by-step explanation:
True, Nat Turner's Rebellion sparked fear among southern whites in a way that no other rebellion had done before. In response, southern states took drastic measures to reinforce the institution of slavery and limit potential future rebellions. Virginia's legislature, which was already reconsidering the state constitution, put an end to discussions of making manumission easier. Instead, they passed legislation that, among other restrictions, made it illegal to teach slaves, free blacks, or mulattoes to read or write. Religious meetings held by black congregations were also regulated, requiring a licensed white minister to be in attendance.
This was presumably to ensure that messages about slavery and freedom were controlled. The intensified fear of rebellion and the subsequent crackdowns were mirrored in other southern states as well, leading to broad implementations of what would come to be known as Black Codes.
