History of the US-Mexico Border

The US-Mexico border’s history is a story of shifting landscapes, politics, and migration that goes back to the early 1800s. It was first established in 1848 after the Mexican-American War through the Treaty of Guadalupe Hidalgo. This treaty gave a large part of Mexico’s northern land to the United States, which includes today’s California, Arizona, New Mexico, and Texas. In 1853, the Gadsden Purchase added another strip of land to the U.S. to help build a southern railroad. Over time, the border changed from being a mostly open area to a more controlled and monitored one, reflecting the political, social, and economic changes between the two countries.
