Question

Mexico insisted that the southern border of Texas was the ______ River, and the U.S. said it was the ___ ______ River.

Answer 1

Mexico insisted that the southern border of Texas was the Rio Grande River, and the U.S. said it was the Nueces River.

Step-by-step explanation:

During the Texas-Mexico border dispute in the 19th century, Mexico insisted that the southern border of Texas was the Rio Grande River, while the United States argued that it was the Nueces River.

This difference in interpretation of the border contributed to tensions and ultimately played a role in the outbreak of the Mexican-American War (1846–1848).

The Treaty of Guadalupe Hidalgo, which ended the war, established the Rio Grande as the southern border of Texas.
