Why were Southerners upset with John Brown raid?

Southerners were upset with John Brown's raid on Harpers Ferry in 1859 because they viewed it as a direct attack on their way of life and an incitement to slave rebellion. Brown's attempt to arm enslaved people fueled fears of violence and insurrection, leading to heightened tensions between the North and South. Additionally, many Southerners saw the support Brown received from some Northerners as evidence of growing abolitionist aggression against the institution of slavery. This incident further deepened the divide between the regions and contributed to the escalating conflict that eventually led to the Civil War.
