Blog #4: Migra!

The U.S. Border Patrol is often portrayed as a simple law enforcement agency tasked with securing the nation’s borders. But its origins tell a darker story of racialized labor control, state violence, and a binational system of exploitation. Historian Kelly Lytle Hernández’s groundbreaking research dismantles the myth of the Border Patrol as a neutral security force, revealing instead how it was designed to regulate Mexican labor, enforce racial hierarchies, and serve economic interests on both sides of the border.

The Birth of the Border Patrol:

In the early 20th century, U.S. agribusiness desperately needed cheap, exploitable labor. Chinese immigrants, indigenous workers, and black migrants had previously filled this role. Still, racist policies, such as the Chinese Exclusion Act (1882) and California’s Alien Land Laws (1913, 1920)-systematically excluded them. Japanese workers, who initially replaced them, were also excluded by racial exclusion laws and international agreements such as the Gentleman’s Agreement of 1907.

In the 1920s, Mexican workers became the primary target of recruitment and repression. They were welcomed when farms needed hands but hunted down when their labor was deemed “illegal”. The Border Patrol, formally established in 1924, was never just about stopping unauthorized migration, it was about managing the flow of Mexican workers to suit American economic needs.

The 1940s Crackdown:

World War II intensified the demand for labor, leading to the Bracero Program (1942–1964), a binational agreement that brought Mexican workers to the U.S. on temporary contracts. But even as the U.S. relied on these workers, it criminalized those who crossed outside the system.

Under Chief W.F. Kelly, the Border Patrol shifted from scattered local enforcement to militarized, large-scale operations. In 1944, Kelly launched Special Mexican Deportation Parties-mobile task forces that conducted mass raids in “hot spot” regions, arresting thousands in a matter of weeks. For example, in June 1944, a single raid in McAllen, Texas, resulted in 6,900 arrests, and by November 1944, California had deported 42,928 Mexican nationals through these operations. These raids weren’t just about removing unauthorized workers-they were about sending a message: Mexican labor was acceptable only on U.S. terms.

Mexican Government Complicity:

Hernández’s work shatters the illusion that border enforcement was a unilateral U.S. project. In reality, the Mexican government played an active role in shaping Border Patrol tactics. When Mexican officials threatened to withdraw from the Bracero Program, the U.S. responded with tougher enforcement, proving that migration control was a negotiated system, not just American policy. Mexican authorities publicly condemned illegal crossings, warning of dangers such as coyote abuse and drownings in the Rio Grande, but quietly allowed migration to continue as an economic escape valve.

The hypocrisy benefited both nations: The U.S. got a disciplined, deportable workforce and Mexico relieved economic pressure while maintaining the appearance of protecting its citizens.

The human cost:

The consequences of this system were devastating for Mexican and Mexican American communities. The number of interrogations increased from 473,720 (1940) to 9.3 million (1943). However, only 0.009% of these interrogations resulted in arrests. This means that millions of innocent people were harassed.

Operation Wetback (1954) was often praised as a success, but it was really about controlling people. Mass deportations made people afraid, separated families, and reinforced racial differences. Even the way the Border Patrol was set up made things worse. Officers and their families lived in close-knit communities within the agency, not in border towns. This made it easier for agents to treat people badly.

The U.S. Border Patrol packed Mexican immigrants into trucks when transporting them to the border for deportation during Operation Wetback.

Hernández’s work shows the Border Patrol as a mix of different things, a group that enforces labor rules, a tool of racial terror, and a way for different countries to work together. The Special Mexican Deportation Parties, internal staffing problems, and Border Patrol family networks all support her idea that enforcement was never just about security. It was also about managing race and money across borders.

However, a deeper look at migrant agency, gender dynamics, and non-Mexican targets could further complicate her narrative. One of her most important contributions is her discussion of how Mexican state influence played a role in the border’s construction. This shows that the border was not decided by the U.S. alone, but was created through negotiations where the U.S. had more power.
