Which of the following did mexico and the republic of texas continue to fight about in the 1840s? the location of the us-mexico border, the practice of slavery in texas, the location of the mexico-texas border, the practice of slavery in mexico

The correct answer is C) the location of the Mexico-Texas border.

On the 1840’s, Mexico and the Republic of Texas continue to fight about the location of Mexico-Texas border.

The government of Mexico and Texas disagreed on the location of the border. Texans considered its border the Rio Grande. Mexico did not agree on that. The government of Mexico considered the border with Texas the Nueces River. In 1845, when the United States annexed Texas, the problems increased in size. In 1846 the United States declared war against Mexico, initiating the Mexican-American War that ended in 1848 with the Treaty of Guadalupe-Hidalgo.
