Identifying the Mexican-American War and its outcome. The conflict stretched from 1846 to 1848 and concluded with the Treaty of Guadalupe Hidalgo. It grew out of disputes over Texas and other western territories, leading to U.S. forces winning key battles and pushing toward negotiation. The treaty established the Rio Grande as the border for Texas and forced Mexico to cede a large stretch of its northern lands—California, Nevada, Utah, Arizona, New Mexico, and parts of Colorado and Wyoming—to the United States. In exchange, the U.S. paid Mexico $15 million and assumed Mexican debts owed to American citizens. This dramatically expanded U.S. territory and reshaped the map of North America. The other wars listed occurred in different times: the War of 1812 was earlier, the Spanish-American War happened in 1898, and the Mexican Civil War was an internal Mexican conflict later in the 19th century.
