The Mexican-American War began following disputes over Texas and border claims in 1846.

The Mexican-American War began when tensions over the annexation of Texas led to a military conflict between the United States and Mexico. The official start of the war was marked by a skirmish between Mexican and American troops along the Rio Grande on April 25, 1846. This event escalated into a full-scale war that lasted for two years, resulting in significant territorial gains for the United States. The outcome of the war saw Mexico ceding vast territories to the United States, including present-day California, Nevada, Utah, Arizona, and parts of Colorado, New Mexico, and Wyoming. The conflict had far-reaching consequences for both countries and reshaped the geopolitical landscape of North America. #MexicanAmericanWar #USA #HistoricalConflict #TerritorialExpansion
