Step-by-step explanation:
Impact of John Brown's Raid on Harper's Ferry
John Brown's Raid on Harper's Ferry in 1859 was a seminal event that contributed significantly to the rising tensions between the North and South, leading up to the Civil War. The raid, which was an attempt to initiate an armed slave revolt, did not result in the emancipation of enslaved individuals in Virginia but rather led to increased violence and mistrust between the two regions. Southerners perceived John Brown as a terrorist and his actions as indicative of the lengths to which Northerners would go to abolish slavery. This conviction grew and was manifested in various forms, including heightened support for secession in Southern states.
Through the raid, issues such as state rights and the moral conflict over slavery were drawn into even sharper focus. The violence and divisiveness of the period set the stage for the Election of 1860, which saw Abraham Lincoln rise to the presidency, prompting the secession of the lower South and the birth of the Confederate States of America.
