What are John Brown Mysteries? ...the local slaves who supported Brown's raid...Harpers Ferry rifles in an attic in Catonsville, Maryland...two trains, stopped by armed black men on October 17, 1859...the self defense organization called African Mysteries... Who are Allies for Freedom? We research and write on the events of John Brown's revolutionary movement, and evidence of African leadership and connectivity. We are teachers and local history activists, artists and photographers--and longtime members of civil rights associations in West Virginia and Maryland, northern California, and Canada.
