Introduction : history of US border
The history of the United States-Mexico border is filled with tales of conflict, migration, and cultural exchange. However, one lesser-known chapter in this complex history is the story of “Texas fever,” a deadly cattle disease that had profound implications for the development of the American West and the shaping of the borderlands. This article delves into the history of Texas fever, its impact on the cattle industry, and how it influenced the dynamics along the US-Mexico border.

What is Texas Fever? : history of US border
Texas fever, also known as bovine babesiosis, is a disease caused by a protozoan parasite transmitted by ticks. The disease primarily affects cattle, history of US border causing symptoms such as high fever, anemia, and death. In the late 19th century, Texas fever posed a significant threat to the burgeoning cattle industry in the United States, particularly in the southern states. history of US border
Origins of the Disease
The disease was first identified in Texas, hence the name “Texas fever.” The cattle herds in Texas were particularly susceptible to the disease, as the region’s warm climate provided an ideal environment for the ticks that carried the protozoan parasite. history of US border However, Texas longhorns, a breed that had adapted to the harsh conditions of the region, developed a level of resistance to the disease. This resistance, however, was not shared by cattle from other parts of the country, which proved disastrous as the cattle drives from Texas began to expand northward.
The Spread of Texas Fever
As Texas cattle were driven north to markets in Kansas, Missouri, and other states, they brought the disease with them. Northern cattle, which had no natural resistance to Texas fever, were particularly vulnerable, leading to devastating outbreaks that decimated herds. The disease spread rapidly, history of US border causing significant economic losses for cattle ranchers and leading to growing tensions between southern and northern cattlemen. history of US border
The Impact on the Cattle Industry
The spread of Texas fever had far-reaching consequences for the American cattle industry. The disease created a rift between southern and northern cattlemen, history of US border as the latter sought to protect their herds from the deadly disease. This tension played a significant role in shaping the policies and practices that governed the cattle trade and the movement of livestock across state lines. history of US border

The Quarantine Laws
In response to the threat of Texas fever, several states in the Midwest and Northeast enacted quarantine laws to prevent the importation of Texas cattle. history of US border These laws prohibited the entry of cattle from Texas during certain times of the year when the risk of disease transmission was highest. The quarantine laws were controversial, as they effectively cut off Texas ranchers from lucrative northern markets and exacerbated regional tensions.
The Role of the US Government
The federal government eventually intervened to address the crisis, establishing the Bureau of Animal Industry in 1884. The bureau was tasked with controlling the spread of livestock diseases, including Texas fever, and played a crucial role in developing strategies to combat the disease. This included efforts to eradicate the ticks that transmitted the disease and the development of quarantine stations along the cattle trails to inspect and treat herds before they were allowed to move further north.
Texas Fever and the US-Mexico Border
The impact of Texas fever extended beyond the United States and into Mexico, where the disease also posed a significant threat to cattle herds. The movement of cattle across the US-Mexico border became a contentious issue, as both countries sought to protect their livestock industries from the disease.
Cross-Border Tensions
The spread of Texas fever led to increased tensions between the United States and Mexico, as American ranchers blamed Mexican cattle for introducing the disease into the country. These tensions were further exacerbated by the fact that the border region was a hotspot for cattle rustling and other illicit activities, making it difficult to control the movement of livestock and the spread of disease.
In response to the challenges posed by Texas fever, both the US and Mexican governments began to develop more formal systems for managing the movement of cattle across the border. This included the establishment of inspection stations and the implementation of measures to prevent the spread of the disease, such as dipping cattle in chemical solutions to kill ticks before they were allowed to cross the border.
The Legacy of Texas Fever
While Texas fever is no longer the threat it once was, its legacy can still be seen in the systems and policies that govern the cattle industry and the US-Mexico border today. The disease played a significant role in shaping the development of the American West, influencing everything from the rise of the cattle industry to the creation of modern veterinary practices.
Advances in Veterinary Science
The battle against Texas fever led to significant advances in veterinary science, including the development of vaccines and treatments for the disease. The research conducted to combat Texas fever also contributed to a broader understanding of tick-borne diseases, benefiting both human and animal health.
Shaping the US-Mexico Border
The efforts to control Texas fever were instrumental in shaping the US-Mexico border as we know it today. The disease highlighted the need for a more structured and regulated border, leading to the creation of systems and practices that continue to influence border management and cross-border trade.
Conclusion
The story of Texas fever is a lesser-known but crucial chapter in the history of the US-Mexico border. The disease had a profound impact on the cattle industry and the development of the American West, shaping the policies and practices that govern the movement of livestock and the management of the border.

While the threat of Texas fever has long since passed, its legacy lives on in the systems and structures that continue to define the US-Mexico border and the cattle industry today.
