Through which treaty did the US acquire 334 million acres in 1848?

The Treaty of Guadalupe Hidalgo, signed in 1848, was pivotal in shaping the territorial boundaries of the United States. This treaty marked the end of the Mexican-American War and resulted in the U.S. acquiring a significant portion of Mexico's territory, which amounted to approximately 334 million acres. This acquisition included present-day California, Nevada, Utah, Arizona, and parts of Colorado, New Mexico, and Wyoming.

The importance of this treaty lies in its role in the westward expansion of the U.S. and the concept of Manifest Destiny, which held that the nation was destined to expand across the continent. The other treaties listed do not relate to the same historical context of land acquisition from Mexico. The Treaty of Paris primarily dealt with the end of the American Revolutionary War, the Treaty of Versailles marked the end of World War I, and the Treaty of Ghent concluded the War of 1812, none of which involved the large-scale territorial acquisition from Mexico that resulted from the Treaty of Guadalupe Hidalgo.
