Question 24

Dispute over Texas-Mexico border

One of the primary causes of the 1846-48 U.S.-Mexico War was the dispute over the Texas-Mexico border, particularly following the annexation of Texas by the United States. This territorial disagreement escalated tensions between the two nations, ultimately leading to military conflict.

A) Pancho Villa raids

Pancho Villa's raids occurred much later, in the early 20th century, specifically in the 1910s. Therefore, they are not relevant to the causes of the U.S.-Mexico War of 1846-48, making this option incorrect.

B) Dispute over Texas-Mexico border

This option accurately represents the core issue that fueled the conflict. The U.S. claimed the Rio Grande as the southern border of Texas, while Mexico asserted that the Nueces River was the correct boundary. This fundamental disagreement over territory was a significant catalyst for the war.

C) California statehood

While California's status did become a concern during the war, it was not a direct cause of the conflict. The war was primarily initiated due to border disputes and the annexation of Texas, rather than California's pursuit of statehood.

D) U.S. occupation of Veracruz

The occupation of Veracruz occurred later in the context of U.S.-Mexico relations and was not a cause of the 1846-48 war. This option is incorrect as it pertains to a different historical event, specifically the Mexican Revolution and its aftermath.

Conclusion

The dispute over the Texas-Mexico border was the definitive cause of the 1846-48 U.S.-Mexico War, as it directly led to military engagements. Other options either relate to events outside this time period or do not address the fundamental territorial disagreements that sparked the conflict. Thus, Option B stands out as the correct answer.
