In this book, James Lewis demonstrates the centrality of American ideas about and concern for the union of the states in the policymaking of the early republic. For four decades after the nation's founding in the 1780s, he says, this focus on securing a union operated to blur the line between foreign policies and domestic concerns. Such leading policymakers as Thomas Jefferson, James Madison, James Monroe, John Quincy Adams, and Henry Clay worried about the challenges to the goals of the Revolution that would arise from a hostile neighborhood--whether composed of new nations outside the union or the existing states following a division of the union. At the center of Lewis's story is the American response to the dissolution of Spain's empire in the New World, from the transfer of Louisiana to France in 1800 to the independence of Spain's mainland colonies in the 1820s. The breakup of the Spanish empire, he argues, presented a series of crises for the unionist logic of American policymakers, leading them, finally, to abandon a crucial element of the distinctly American approach to international relations embodied in their own federal union.

In contrast to later imperial pursuits in Mexico, Cuba, and the Philippines, the early United States extended its boundaries through less sensational modes of territorialization: land deals, slavery expansion, treaty diplomacy, immigration and settlement, and the addition of new states on the border. Never the exclusive top-down product of any single strategic plan, empire building relied rather on a hazy, ever-shifting boundary between state and non-state action. Territories of Empire examines the border writings of U.S. explorers, politicians, travelers, novelists, merchants, newspapermen, and other eye-witnesses to the rapid expansion of the United States in the aftermath of the Louisiana Purchase. It traces how different authors and texts imagined the relations between nation-state and border and reveals how continental ambitions were achieved through the uneven and unpredictable process of territorialization. Andy Doolen looks to writings as dissimilar as Kentucky newspaper accounts of the Aaron Burr conspiracy, the explorer Zebulon Pike's 1810 account of making peace with the Santee Sioux before becoming terribly lost near the upper Rio Grande, and Timothy Flint's 1826 novel about a young New Englander who fights in the Mexican independence struggle in showing how national sentiments were galvanized in support of greater territorial and commercial growth. To this end, Doolen makes clear how both private citizens and government officials collectively authored the spatial logic of a continental republic. Combining textual analysis with theories of transnationalism and empire, Territories of Empire reconstructs the development of a continental imaginary highly attuned to the objectives of U.S. imperialism, while often betraying an unsettling awareness of resistance and diversity beyond the border.

This fascinating study sheds new light on antebellum America's notorious "filibusters--the freebooters and adventurers who organized or participated in armed invasions of nations with whom the United States was formally at peace. Offering the first full-scale analysis of the filibustering movement, Robert May relates the often-tragic stories of illegal expeditions into Cuba, Mexico, Ecuador, Nicaragua, and other Latin American countries and details surprising numbers of aborted plots, as well. May investigates why thousands of men joined filibustering expeditions, how they were financed, and why the U.S. government had little success in curtailing them. Surveying antebellum popular media, he shows how the filibustering phenomenon infiltrated the American psyche in newspapers, theater, music, advertising, and literature. Condemned abroad as pirates, frequently in language strikingly similar to modern American denunciations of foreign terrorists, the filibusters were often celebrated at home as heroes who epitomized the spirit of Manifest Destiny. May concludes by exploring the national consequences of filibustering, arguing that the practice inflicted lasting damage on U.S. relations with foreign countries and contributed to the North-South division over slavery that culminated in the Civil War.
