As he approached the rostrum to speak before historians gathered in Chicago in 1893, Frederick Jackson Turner appeared nervous. He was presenting a conclusion that would alarm all who believed that westward expansion had fostered the nation’s principles of democracy. His conclusion: The frontier—the encounter between European traditions and the native wilderness—had played a fundamental role in shaping American character, but the American frontier no longer existed. Turner’s statement raised questions. How would Americans maintain their unique political culture and innovative spirit in the absence of the frontier? How would the nation expand its economy if it could no longer expand its territory?
Later historians would see Turner’s Frontier Thesis as deeply flawed, a gross mischaracterization of the West. But the young historian’s work greatly influenced politicians and thinkers of the day. Like a muckraker, Turner exposed the problem; others found a solution by seeking out new frontiers in the creation of an American empire.
