Nat turner’s efforts in 1831 brought

 Stricter measures to prevent slave uprisings in southern states  

Explanation:

Slave rebellions also began to occur and caused slave owners to implement even more harsh restrictions on slaves. The Black preacher, Nat Turner, believed his mission on Earth was to free his people from slavery. Seeing an 1831 solar eclipse as a message from God, he led a slave rebellion on four Virginia plantations. Approximately 60 whites were killed before Turner and his followers were captured, tried, and executed. Fear and anger over the murder of primarily white women and children led to many innocent Blacks becoming victims of mob violence. Virginia, a state that had been considering a ban on slavery, instead passed a series of laws to strengthen the institution of slavery. Other southern states quickly passed laws that emulated Virginia’s revised slave codes to reflect more strict control.
