Hess, SophieHollow Ground: Industry, Extraction, and Ecology in the Floodplains of Early Maryland,” investigates histories of natural resource commodification, environment, and culture in the Patapsco River Valley, or “The Hollow” as it was called by its first European settlers. Beginning in the seventeenth century, English colonists seized the powerful currents of the Patapsco and the forests surrounding it, the ancestral floodplains of Piscataway and Susquehannock peoples, to build large-scale agricultural projects and industrial factories. These operations altered the environment, and as the valley grew into a center of extractive production, its communities experienced more frequent and severe floods which have continued into the present. This dissertation examines these entwined consequences of environmental capitalism and settler colonialism through a site-specific, multi-century lens, studying how humans, plants, and animals within various spaces of production—iron furnaces, wheat fields, grist and cotton mills, schools, prisons, local governments, and family units —experienced industrialization. It traces trace labor ecologies within communities of enslaved, convict, and low-wage workers, and the ways that soil exhaustion, flooding, and other environmental forces both threatened these enclaves and created opportunities for freedom. This work uses a microhistorical methodology to intervene in histories of energy transition, labor, and the Anthropocene. “Hollow Ground” argues that early American industrialism can help us to better understand how local desires for capital growth have accumulated into global processes of toxic emissions, and how the frontline issues faced by post-industrial communities today relate not only to global production but to local histories of extraction and the culture that perpetuates it. These same communities also hold critical histories of commoning, stewardship, labor resistance, and environmentalism that can help create a blueprint for survival in the face of the climate crisis.enHollow Ground: Industry, Extraction, and Ecology in the Floodplains of Early MarylandDissertationHistoryEnvironmental studiesCapitalismCultural HistoryFloodingPatapsco RiverSettler ColonialismState Parks
