Through the Treaty of Guadalupe Hidalgo in 1848, the direct aftermath of the U.S-Mexico War between 1846 and 1848, and later on the Garden Purchase in 1853, the U.S. successfully incorporated Mexico’s northernmost provinces into its sovereignty, in return for $15 million and, later on, an additional $10 million compensation package for Mexico.
The Treaty is of interest to the project because it was a critical moment that profoundly shaped the U.S-Mexico border we know today.
