This occasional paper is a concise overview of the history of the US Army's involvement along the Mexican border and offers a fundamental understanding of problems associated with such a mission. Furthermore, it demonstrates how the historic themes addressed disapproving public reaction, Mexican governmental instability, and insufficient US military personnel to effectively secure the expansive boundary are still prevalent today.

An extensive history examining how North American nations have tried (and often failed) to police their borders, Border Policing presents diverse scholarly perspectives on attempts to regulate people and goods at borders, as well as on the ways that individuals and communities have navigated, contested, and evaded such regulation. The contributors explore these power dynamics though a series of case studies on subjects ranging from competing allegiances at the northeastern border during the War of 1812 to struggles over Indian sovereignty and from the effects of the Mexican Revolution to the experiences of smugglers along the Rio Grande during Prohibition. Later chapters stretch into the twenty-first century and consider immigration enforcement, drug trafficking, and representations of border policing in reality television. Together, the contributors explore the powerful ways in which federal authorities impose political agendas on borderlands and how local border residents and regions interact with, and push back against, such agendas. With its rich mix of political, legal, social, and cultural history, this collection provides new insights into the distinct realities that have shaped the international borders of North America.

Political awareness of the tensions in U.S.-Mexico relations is rising in the twenty-first century; the American history of its treatment of illegal immigrants represents a massive failure of the promises of the American dream. This is the untold history of the United States Border Patrol from its beginnings in 1924 as a small peripheral outfit to its emergence as a large professional police force that continuously draws intense scrutiny and denunciations from political activism groups. To tell this story, MacArthur "Genius" Fellow Kelly Lytle Hernández dug through a gold mine of lost and unseen records and bits of biography stored in garages, closets, an abandoned factory, and in U.S. and Mexican archives. Focusing on the daily challenges of policing the Mexican border and bringing to light unexpected partners and forgotten dynamics, Migra! reveals how the U.S. Border Patrol translated the mandate for comprehensive migration control into a project of policing immigrants and undocumented “aliens” in the U.S.-Mexico borderlands.
