Which one of the following was an effect of John Browns raid?

Answer 1

John Brown's raid on Harpers Ferry in 1859 heightened tensions between the North and South, intensifying the national debate over slavery. It galvanized abolitionist sentiment in the North while inciting fear and anger in the South, leading to increased calls for secession. Brown's actions also contributed to the growing divide that ultimately culminated in the Civil War. Additionally, his trial and execution made him a martyr for the abolitionist cause.
