Treaty of Guadalupe Hidalgo Signed

The Treaty of Guadalupe Hidalgo was signed at the Basilica of Guadalupe north of Mexico City on February 2, 1848. Mexico ceded approximately 525,000 square miles — over half its pre-war territory — including present-day California, Nevada, Utah, most of Arizona and New Mexico, and parts of Colorado, Wyoming, Kansas, and Oklahoma. The US paid Mexico $15 million and assumed $3.25 million in claims by American citizens against Mexico. The Rio Grande became the permanent US-Texas border.
