Known as the first major conflict driven by the doctrine of Manifest Destiny, the Mexican-American War (1846-1848) was a pivotal event in North American history that reshaped the continent's boundaries, gave birth to new states, and left an enduring impact on the region's politics, economy, and culture.
The seeds of conflict were sown in 1836, when the Republic of Texas declared independence from Mexico. The Lone Star State, as it came to be known, sought annexation by the United States, a prospect that Mexico deeply resented.
