This course offers an introduction to the key questions, methods, and sources in the field of environmental history. We will ground our study of environmental history in place-based case studies drawn from across areas over which the United States has claimed sovereignty, throughout North America, the Caribbean, the Pacific, and the Arctic. Drawing examples from across what has sometimes been called “the Greater United States,” the course explores how nature, people, and environmental change transcend and trouble the boundaries of the nation-state. By thinking transnationally and comparatively beyond the traditional bounds of U.S. environmental history and the continental United States, we will consider the environmental and social impacts of the far reach of U.S. empire and colonialism. Over the course of the semester, we will focus on themes such as conservation, extraction, science, and migration as we consider the history of how various agents of U.S. empire and communities living in U.S. territories and colonies have thought about and interacted with nature and state power at large and small scales.
