What treaty ended the Mexican War and resulted in significant land acquisitions for the U.S.?

The Treaty of Guadalupe-Hidalgo is the correct answer because it officially ended the Mexican-American War, which lasted from 1846 to 1848. Signed on February 2, 1848, this treaty had significant repercussions for the United States as it resulted in the U.S. acquiring a vast portion of Mexico’s territory. The land obtained included present-day California, Nevada, Utah, Arizona, and parts of Colorado and New Mexico, dramatically expanding the geographical and cultural landscape of the nation.

This treaty marked a pivotal moment in American history, reflecting the prevailing attitudes of Manifest Destiny, which suggested that the United States was destined to expand across the North American continent. The outcomes of the treaty also had long-term impacts on U.S.-Mexico relations and set the stage for future conflicts and discussions related to expansionism and the status of territories acquired through war.
