This collaborative multi-authored volume integrates interdisciplinary approaches to ethnic, imperial, and national borderlands in the Iberian World (16th to early 19th centuries). It illustrates the historical processes that produced borderlands in the Americas and connected them to global circuits of exchange and migration in the early modern world. The book offers a balanced state-of-the-art educational tool representing innovative research for teaching and scholarship. Its geographical scope encompasses imperial borderlands in what today is northern Mexico and southern United States; the greater Caribbean basin, including cross-imperial borderlands among the island archipelagos and Central America; the greater Paraguayan river basin, including the Gran Chaco, lowland Brazil, Paraguay, and Bolivia; the Amazonian borderlands; the grasslands and steppes of southern Argentina and Chile; and Iberian trade and religious networks connecting the Americas to Africa and Asia. The volume is structured around the following broad themes: environmental change and humanly crafted landscapes; the role of indigenous allies in the Spanish and Portuguese military expeditions; negotiations of power across imperial lines and indigenous chiefdoms; the parallel development of subsistence and commercial economies across terrestrial and maritime trade routes; labor and the corridors of forced and free migration that led to changing social and ethnic identities; histories of science and cartography; Christian missions, music, and visual arts; gender and sexuality, emphasizing distinct roles and experiences documented for men and women in the borderlands. While centered in the colonial era, it is framed by pre-contact Mesoamerican borderlands and nineteenth-century national developments for those regions where the continuity of inter-ethnic relations and economic networks between the colonial and national periods is particularly salient, like the central Andes, lowland Bolivia, central Brazil, and the Mapuche/Pehuenche captaincies in South America. All the contributors are highly recognized scholars, representing different disciplines and academic traditions in North America, Latin America and Europe.

Long before the Spanish colonizers established it in 1598, the "Kingdom of Nuevo Mexico" had existed as an imaginary world-and not the one based on European medieval legend so often said to have driven the Spaniards' ambitions in the New World. What the conquistadors sought in the 1500s, it seems, was what the native Mesoamerican Indians who took part in north-going conquest expeditions also sought: a return to the Aztecs' mythic land of origin, Aztlan. Employing long-overlooked historical and anthropological evidence, Danna A. Levin Rojo reveals how ideas these natives held about their own past helped determine where Spanish explorers would go and what they would conquer in the northwest frontier of New Spain-present-day New Mexico and Arizona. Return to Aztlan thus remaps an extraordinary century during which, for the first time, Western minds were seduced by Native American historical memories. Levin Rojo recounts a transformation-of an abstract geographic space, the imaginary world of Aztlan, into a concrete sociopolitical place. Drawing on a wide variety of early maps, colonial chronicles, soldier reports, letters, and native codices, she charts the gradual redefinition of native and Spanish cultural identity-and shows that the Spanish saw in Nahua, or Aztec, civilization an equivalence to their own. A deviation in European colonial naming practices provides the first clue that a transformation of Aztlan from imaginary to concrete world was taking place: Nuevo Mexico is the only place-name from the early colonial period in which Europeans combined the adjective "new" with an American Indian name. With this toponym, Spaniards referenced both Mexico-Tenochtitlan, the indigenous metropolis whose destruction made possible the birth of New Spain itself, and Aztlan, the ancient Mexicans' place of origin. Levin Rojo collects additional clues as she systematically documents why and how Spaniards would take up native origin stories and make a return to Aztlan their own goal-and in doing so, overturns the traditional understanding of Nuevo Mexico as a concept and as a territory.
