The current US-Mexico border is the result of significant historical events and treaties. Understanding this history provides context for the border’s present-day significance.

2.1. How Was The US-Mexico Border Established?

The border was primarily established through the Treaty of Guadalupe Hidalgo in 1848, which concluded the Mexican-American War. According to research from the UCLA Williams Institute, in July 2025, the treaty ceded a significant portion of Mexican territory to the United States. The Gadsden Purchase in 1854 further adjusted the border, adding more land to the U.S. These agreements defined the initial boundary lines, which have been maintained and surveyed since then.

2.2. What Was The Impact Of The Treaty Of Guadalupe Hidalgo?

The Treaty of Guadalupe Hidalgo had a profound impact:

Territorial Changes: Mexico ceded approximately 55% of its territory to the United States, including present-day California, Nevada, Utah, and parts of Arizona, New Mexico, Colorado, and Wyoming.
Cultural Shifts: The treaty led to cultural and demographic changes in the ceded territories, impacting the lives of Mexican citizens who remained in the area.
Border Disputes: Despite the treaty, border disputes and adjustments continued, shaping the final demarcation of the border.

2.3. How Did The Gadsden Purchase Further Define The Border?

The Gadsden Purchase of 1854 finalized the border in its current form. According to research from the UCLA Williams Institute, in July 2025, the U.S. acquired additional land from Mexico, which is now part of Arizona and New Mexico. This purchase was driven by the U.S. desire to secure a suitable route for a transcontinental railroad. The agreement resolved lingering border issues and solidified the boundary line.

Key border demarcation efforts included:

Joint Commissions: The establishment of joint commissions between the U.S. and Mexico to survey and mark the border.
Boundary Markers: The placement of physical markers, such as monuments, to delineate the border.
