Answer: B) panic and fear of black people in the Southern states.
The Nat Tuner's Rebellion was a slave revolt that took place in Virginia in 1831. It was named after Nathanial Turner, a black slave. Well-educated, he became a leader in his plantation, arguing that he had been chosen by God to free the slaves. The rebellion killed 55 to 65 people, at least 51 being white.
The rebellion spread panic throughout the South, leading to the development of new legislation limiting the "rights" of slaves, such as assembly and education. White militias were organized in retaliation, and these killed approximately 120 black Americans.
