The Mexican-American War

The Mexican-American War took place from 1846 to 1848 and was primarily driven by the United States' desire to expand its territory. Tensions escalated when the U. S. annexed Texas, which had won independence from Mexico. This led to disputes over borders and resulted in armed conflict.

The war ended with the signing of the Treaty of Guadalupe Hidalgo, which resulted in the U. S. acquiring significant territories, including California and New Mexico. The conflict had lasting implications, reshaping the map of North America and intensifying debates over slavery in the newly acquired territories.
