In the 1840s, Mexico and the Republic of Texas continued to fight primarily about **the location of the US-Mexico border**. The annexation of Texas by the United States in 1845 exacerbated tensions, particularly concerning whether the border was the Nueces River or the Rio Grande. This disagreement over the boundary contributed to the outbreak of the Mexican-American War in 1846.
