@aidenhistorypolitics: Mexican American Nationalist war Edit #edit #nationlist #usa #right #mexico war The Mexican–American War was an armed conflict fought between the United States and Mexico from April 1846 to February 1848. Causes of the War • Texas Annexation: The U.S. annexed the Republic of Texas in 1845, which Mexico still considered part of its territory. • Boundary Dispute: The two nations disagreed on the southern border of Texas—the U.S. claimed the Rio Grande, while Mexico claimed the Nueces River further north. • Manifest Destiny: U.S. President James K. Polk sought to fulfill the belief that the U.S. was destined to expand across the continent to the Pacific Ocean, leading to failed offers to purchase California and New Mexico from Mexico. Major Campaigns and Battles • Northern and Border Campaigns: U.S. General Zachary Taylor won early battles at Palo Alto and Resaca de la Palma in April 1846, followed by victories at Monterrey and Buena Vista. • California and New Mexico: U.S. forces and naval units under Stephen Kearny, John C. Frémont, and Robert F. Stockton occupied New Mexico and California. • Central Mexico & Capture of the Capital: General Winfield Scott led an amphibious landing at Veracruz, fought through Cerro Gordo, and captured Mexico City in September 1847. • Los Niños Héroes: Young Mexican military cadets bravely defended Chapultepec Castle in Mexico City against U.S. forces. Outcome and Treaty of Guadalupe Hidalgo • Peace Agreement: Signed on February 2, 1848, the Treaty of Guadalupe Hidalgo officially ended the war. • The Mexican Cession: Mexico ceded over 500,000 square miles of territory—including present-day California, Nevada, Utah, Arizona, New Mexico, and parts of Colorado and Wyoming—to the U.S.. • Compensation: The U.S. paid Mexico $15 million and assumed claims of U.S. citizens against the Mexican government. Long-Term Impact • Sectionalism and Civil War: Gaining vast new territories reopened intense U.S. political debates over the expansion of slavery (such as through the Wilmot Proviso), directly contributing to the tensions that caused the American Civil War. • Military Training: Many future American Civil War generals (such as Ulysses S. Grant and Robert E. Lee) gained critical combat experience during this conflict. Watch this breakdown of the conflict's
