Texas claimed the Rio Grande as its southern border, a claim that was disputed by Mexico. The disagreement over the boundary was one of the significant issues that led to the Mexican-American War in the mid-19th century. Mexico argued that the southern border of Texas was the Nueces River, while Texas and later the U.S. maintained that it was the Rio Grande.

Answer

Wrong

I apologize for any confusion. The correct southern border claimed by Texas that was disputed by Mexico was indeed the Rio Grande. Mexico argued that the border was at the Nueces River. If there's a different context or specific detail you're looking for, please let me know!
