Step-by-step explanation:
Harpers Ferry National Historic Park is located in what is now the state of West Virginia. This site is significant because it was the location of a notable event in the years leading up to the Civil War - John Brown's raid on Harper's Ferry. In October 1859, the radical abolitionist John Brown led a group of men in an attack on the federal arsenal at Harpers Ferry with the goal of arming enslaved people and initiating a revolt against slavery. Although the raid was ultimately unsuccessful and Brown was captured and executed, the event is marked as an important point in the antislavery movement and heightened tensions between the North and the South. The park today preserves the historic site where these momentous events unfolded.
