Prado challenges false boundaries scholars have constructed between the Spanish and Portuguese empires. He reveals how commercial, family, and political networks linked the two worlds in the South Atlantic."—Hal Langfur, author of The Forbidden Lands: Colonial Identity, Frontier Violence, and the Persistence of Brazil’s Eastern Indians, 1750–1830 "In Edge of Empire, Prado switches smoothly between local, regional, and imperial frames of analysis and offers a compelling alternative to traditional nation-centered narratives about the end of Iberian colonialism in South America. This book does not just employ an Atlantic paradigm, it improves on it." —Bianca Premo, Associate Professor of History, Florida International University
