Slave Revolt Scare (Lexington, KY)
The fear of a slave revolt was such a terrifying thought that a number of slaves were arrested and jailed in Lexington, KY in 1810; there was a supposed slave revolt plot. Rumors of slave uprisings were constantly circulated. In response, in 1811 the Kentucky Legislature made insurrection or a conspiracy to start an insurrection by [free] Negroes or slaves punishable by death.
