What side was john brown on union or confederacy?

John Brown was an ardent abolitionist who opposed slavery and fought for its eradication. He was not aligned with either the Union or the Confederacy in the traditional sense, as his primary focus was on ending slavery rather than supporting either side in the Civil War. His actions, including the raid on Harpers Ferry in 1859, were aimed at inciting a slave uprising and promoting the abolitionist cause. Brown's radical approach ultimately made him a martyr for the abolitionist movement.
