Although it failed miserably what was a consequence of John Brown's raid on the Federal arsenal at Harper's Ferry?

John Brown's raid on Harper's Ferry in 1859, despite its failure, heightened national tensions over slavery and galvanized abolitionist sentiment in the North. It alarmed Southern slaveholders, leading them to fear that such insurrections could become more common. The raid also drew attention to the deep divisions in the country, contributing to the polarization that ultimately led to the Civil War. Brown's execution turned him into a martyr for the abolitionist cause, inspiring further activism against slavery.
