Treaty of Guadalupe Hidalgo
Treaty of Guadalupe Hidalgo (2 Feb 1848) - The Treaty of Guadalupe Hidalgo was a treaty between Mexico and United States signed in Guadalupe Hidalgo ending the Mexican War (1846-1848).
Officially proclaimed on 4 Jul 1848.
All or parts of 10 U.S. states were formed from the land ceded by Mexico in the treaty. In return the, U.S. agreed to pay 15 million dollars in five yearly payments to Mexico and to assume the debt of 3.25 million dollars that Mexico owed to U.S. citizens. The Gadsden Purchase in 1853 added the present day lower parts of New Mexico and Arizona to the lands obtained from Mexico.
The exact borders were surveyed and laid out by a series of boundary commissions. A series of 53 markers were eventually placed at critical points along the border, many of them crudely built. Many of the markers had to be reset and rebuilt in the 1890s.
