What treaty ended the Mexican-American War and recognized Texas as part of the U.S.?

The Treaty of Guadalupe-Hidalgo is the correct answer because it formally concluded the Mexican-American War, which lasted from 1846 to 1848. This treaty was signed on February 2, 1848, and it had significant implications for U.S. territorial expansion. One of the key provisions of the treaty was the recognition of Texas as part of the United States, reinforcing the annexation of Texas that had occurred in 1845.

Additionally, the treaty resulted in Mexico ceding a large portion of its northern territory, including present-day California, Arizona, New Mexico, Nevada, Utah, and parts of Colorado and Wyoming, to the United States. This acquisition significantly altered the borders of the United States and contributed to the concept of Manifest Destiny, the belief that the U.S. was destined to expand across the continent.

In contrast, the other treaties listed do not pertain to the outcomes of the Mexican-American War. The Treaty of Paris is associated with the end of the Revolutionary War, the Treaty of Fort Laramie pertains to agreements with Native American tribes, and the Treaty of Versailles ended World War I. Each of these treaties addressed different historical contexts and therefore, do not relate to the recognition of Texas within the U.S.
