This in-depth history examines how a stronghold of slavery in Pennsylvania became a central hub for the abolitionist cause. Much like the rest of the nation, South Central Pennsylvania has a fraught history of struggle over slavery. The institution lingered locally for more than fifty years, even as it went virtually extinct everywhere else within Pennsylvania. Gradually, abolitionist views prevailed as the region became an important destination for enslaved people escaping the south. The Appalachian Mountains and the Susquehanna River provided natural cover for fugitive, causing an influx of travel along the Underground Railroad. Locals like William Wright and James McAllister assisted these runaways while publicly advocating to abolish slavery. In this expert study, historian Cooper Wingert reveals the struggles between slavery and abolition in South Central Pennsylvania.
