A former town of south-central Mexico, now part of the suburbs of Mexico City. The Virgin of Guadalupe, revered throughout Mexico, is said to have appeared to an Indian convert in this vicinity in 1531, and the basilica erected in her honor is a popular pilgrimage site. On February 2, 1848, a treaty ending the Mexican War was signed here.
When the United States acquired possession of New Mexico, the best portions of the Territory were held in private ownership under Spanish and Mexican grants, which were confirmed by the treaty of Guadalupe-Hidalgo.
Several months later, however, it was separated from these two provinces and became a Territory; in 1836 it was officially designated as a department, and remained as such until ceded to the United States by the treaty of Guadalupe-Hidalgo, in 1848.
By the treaty of Guadalupe-Hidalgo, in 1848, the United States government recognized them as citizens.
It was then occupied by the American army under General Winfield Scott, and held by them until the signing of the treaty of Guadalupe-Hidalgo (May 1848).
