Border Law: The First Seminole War and American Nationhood

The First Seminole War of 1816–1818 played a critical role in shaping how the United States demarcated its spatial and legal boundaries during the early years of the republic. Rooted in notions of American exceptionalism, manifest destiny, and racism, the legal framework that emerged from the war laid the groundwork for the Monroe Doctrine, the Dred Scott decision, and U.S. westward expansion over the course of the nineteenth century, as Deborah Rosen explains in Border Law. When General Andrew Jackson’s troops invaded Spanish-ruled Florida in the late 1810s, they seized forts, destroyed towns, and captured or killed Spaniards, Britons, Creeks, Seminoles, and African-descended people.
