While the literature on slave flight in nineteenth-century North America has commonly focused on fugitive slaves escaping to the U.S. North and Canada, Conditional Freedom: Free Soil and Fugitive Slaves from the U.S. South to Mexico's Northeast, 1803-1861 (Brill, 2024) provides new insights on the social and political geography of freedom and slavery in nineteenth-century North America by exploring the development of southern routes of escape from slavery in the U.S. South and the experiences of self-emancipated slaves in the U.S.–Mexico borderlands. In Conditional Freedom, Thomas Mareite offers a social history of U.S. refugees from slavery, and provides a political history of the clash between Mexican free soil and the spread of slavery west of the Mississippi valley during the nineteenth-century.
