Kirkus Review
A study of how the eponymous demarcation line has long been seen as far more than just an abstract border. The surveying party led by Charles Mason and Jeremiah Dixon was organized in the aftermath of the French and Indian War to settle border disputes among Pennsylvania, Delaware, Maryland, and Virginia. The region, writes Florida State historian Gray, had long been torn by war: neighbor against neighbor, white against Indigenous, with spectacular violence committed against the peaceful peoples of the Susquehanna River area. Indeed, "the story of the Line is really a story of Americans and their relationship to government," a relationship largely marked by hostility and antagonism, and by the usual ironies: The settlers along the borderlands demanded security from the government but resisted paying the taxes to underwrite that protection. Ironically, the Mason-Dixon line, which took that name decades after the survey was completed, would eventually come to be seen as the dividing line between North and South, between slavery and freedom--ironically, that is, because, as Gray notes in this data-rich narrative, for much of the 18th century New York had nearly three times more enslaved people than Pennsylvania, whose Quaker leaders took to abolitionism early on. During the Civil War, though they remained in the Union, Delaware and Maryland allowed slavery, at least in a roundabout way. Their politicians opposed the slave trade but not slavery itself, which had the effect of raising the prices of enslaved people. Delaware defied emancipation, albeit "the position of Delaware's Democrats was more the stuff of farce than even the rudest form of political posturing." Finally, if briefly, the Line marked the division between free and slave states, long after it had acquired ethnic partition lines that more or less continue today, grouping a few Indigenous communities, a small number of African Americans, and sometimes contending European populations dominated by Protestant German and Scots-Irish farmers. A rich history of regional distinctions, especially as they shaped the antebellum Republic. Copyright (c) Kirkus Reviews, used with permission.
