In this Feb. 8, 2017 photo, a mannequin depicting one of abolitionist John Brown’s raiders rests in the attic of the restored farmhouse in Dargan, Md., where Brown’s party launched their failed, 1859 seizure of a federal armory in nearby Harpers Ferry, W.Va. Historians cite Brown’s raid as the opening salvo in the Civil War because it incited strong passions, especially in the slave-holding South. The farmhouse, now a national historic landmark, stands near a dance hall that hosted a dazzling array of black entertainers a century later, during the racially segregated 1950s and early ’60s.
