Mapa de los Estados Unidos de Méjico

This map of Mexico shows the vast expanse of the country as it was organized in 1828, just seven years after winning independence from Spain.

Coahuila y Tejas is outlined in pink with the Nueces River as the southern border of Tejas. Texas would later claim the Rio Grande as its border, a dispute that culminated in war between the United States and Mexico from 1846 to 1848.

This map was used as the basis for another map by the same title published by John Disturnell in the 1840s. The Disturnell map was used to determine the border between Mexico and the United States as part of the Treaty of Guadalupe Hidalgo in 1848.
