The Treaty of Guadalupe Hidalgo, signed in 1848, officially ended the Mexican-American War and established a new boundary between the United States and Mexico. Under the treaty's terms, Mexico ceded over 500,000 square miles of territory, which included present-day California, Arizona, New Mexico, Nevada, Utah, and parts of Colorado and Wyoming. In exchange, the U.S. agreed to pay Mexico $15 million and assume claims by American citizens against the Mexican government. This treaty significantly altered the geographical and political landscape of North America and intensified debates over slavery in the new territories.
