Map of the US-Mexican War of 1846-1848 — This map illustrates the US-Mexican War of 1846-1848, triggered by the US annexation of Texas and a disputed border at the Río Grande. Under President James K. Polk (1845-1849) and a succession of Mexican leaders, fighting spread from the Gulf Coast to the Pacific, reshaping North America's political map.

The conflict unfolded in three main theaters. In the north, US armies pushed across the Río Grande and secured the frontier, halting Mexican counteroffensives. In the west, naval squadrons and volunteer columns occupied California and New Mexico, severing Mexico's Pacific flank. A Gulf-coast landing then opened the road to the Mexican heartland, where a sustained campaign captured the capital and compelled peace. The Treaty of Guadalupe Hidalgo (2 February 1848) ended hostilities: Mexico ceded vast northern territories, including California and New Mexico, and accepted the Río Grande as the Texas boundary.
