Which treaty ended the Mexican-American War?

• A. Treaty of Paris
• B. Treaty of Guadalupe Hidalgo
• C. Adams-Onís Treaty
• D. Treaty of Ghent

Answer: (B)

Ending a conflict through a treaty is what often sets new borders and terms for both nations. The one that ended the Mexican-American War in 1848 was the Treaty of Guadalupe Hidalgo. It forced Mexico to cede a huge portion of its territory to the United States—lands that would become California, Nevada, Utah, Arizona, and parts of Colorado, New Mexico, and Wyoming—while the Rio Grande was recognized as the southern border of Texas. The United States also paid Mexico $15 million and assumed some of Mexico’s debts. This treaty dramatically expanded U.S. territory and intensified debates over the spread of slavery into the new lands, a major issue in the years leading up to the Civil War. By contrast, the other treaties named ended very different conflicts: the Treaty of Paris ended the American Revolutionary War, the Adams-Onís Treaty settled the Florida boundary, and the Treaty of Ghent ended the War of 1812.
