Treaty of Guadalupe Hidalgo

Signed in 1848, the Treaty of Guadalupe Hidalgo ended the war between the United States and Mexico and gave a large portion of Mexico's northern territories to the United States. The language of the treaty was designed to deal fairly with the people who became residents of the United States by default. However, as Richard Griswold del Castillo points out, articles calling for equality and protection of civil and property rights were either ignored or interpreted to favor those involved in the westward expansion of the United States rather than the Mexicans and Indians living in the conquered territories.
