Bridging the multiple histories and present-day iterations of U.S. settler colonialism in North America and its overseas imperialism in the Caribbean and the Pacific, the essays in this groundbreaking volume underscore the United States as a fluctuating constellation of geopolitical entities marked by overlapping and variable practices of colonization. By rethinking the intertwined experiences of Native Americans, Puerto Ricans, Chamorros, Filipinos, Hawaiians, Samoans, and others subjected to U.S. imperial rule, the contributors consider how the diversity of settler claims, territorial annexations, overseas occupations, and circuits of slavery and labor—along with their attendant forms of jurisprudence, racialization, and militarism—both facilitate and delimit the conditions of colonial dispossession. Drawing on the insights of critical indigenous and ethnic studies, postcolonial theory, critical geography, ethnography, and social history, this volume emphasizes the significance of U.S. colonialisms as a vital analytic framework for understanding how and why the United States is what it is today.
