John Brown was a charismatic and deeply religious man who heard the God of the Old Testament speaking to him, telling him to destroy slavery by any means. When Congress opened Kansas territory to slavery in 1854, Brown raised a band of followers to wage war. His men tore pro-slavery settlers from their homes and hacked them to death with broadswords. Brown’s violence pointed ambitious Illinois lawyer and former officeholder Abraham Lincoln toward a different solution to slavery: politics. Lincoln spoke cautiously and dreamed big, plotting his path back to Washington and perhaps to the White House. Yet his caution could not protect him from the vortex of violence Brown had set in motion.
