The Treaty of Guadalupe Hidalgo was signed in February 1848, bringing an official end to the Mexican-American War. Among other things, it moved the southern boundary of the U.S. to the Rio Grande River, instead of the Arkansas River. Part of the original treaty is on display at the El Pueblo History Museum in Pueblo.
History professor Dr. Fawn Amber Montoya coordinates Chicano Studies at Colorado State University-Pueblo. 91.5 KRCC's Abigail Beckman spoke with Montoya about the implications of the treaty, which drastically changed the lives of the people living in this region.
