Abstract
From the colonial era of waterborne transport, through nineteenth-century changes in transportation and communication, to globalization, the history of the Great Lakes Basin has been shaped by the people, goods, and capital crossing and recrossing the U.S.-Canadian border. During the past three centuries, the region has been buffeted by efforts to benefit from or defeat economic and political integration and by the politics of imposing, tightening, or relaxing the bisecting international border.
