Book excerpt: The 2,000-mile-long international boundary between the United States and Mexico gives shape to a unique social, economic, and cultural entity. David Lorey here offers the first comprehensive treatment of the fascinating evolution of the region over the past century. Exploring the evolution of a distinct border society, Lorey traces broad themes in the region's history, including geographical constraints, boom-and-bust cycles, and outside influences. He also examines the seminal twentieth-century events that have shaped life in the area, such as Prohibition, World War II, and economic globalization. Bringing the analysis up to the present, the book considers such divisive issues as the distinction between legal and illegal migration, trends in transboundary migrant flows, and North American free trade. Informative and accessible, this valuable study is ideal for courses on the U.S.-Mexico borderlands, Chicano studies, Mexican history, and Mexican-American history.
