Why did John Brown lead a raid on Harper's Ferry Virginia?

John Brown led a raid on Harper's Ferry, Virginia, in October 1859 to incite a slave rebellion and promote the abolition of slavery in the United States. He aimed to seize the federal armory there, gather weapons, and arm enslaved people, believing that violent uprising was necessary to end slavery. Brown viewed the raid as a pivotal act of resistance against the institution of slavery, although it ultimately failed and led to his capture and execution. His actions, however, heightened tensions between the North and South, contributing to the onset of the Civil War.
