What treaty ended the Mexican War and granted control of Texas to the U.S.?

The Treaty of Guadalupe Hidalgo is significant because it formally ended the Mexican-American War in 1848. Under this treaty, Mexico ceded a vast amount of territory to the United States, which included present-day Texas, California, Arizona, New Mexico, Nevada, and parts of Colorado and Utah. This acquisition significantly expanded the territorial boundaries of the United States, fulfilling the concept of Manifest Destiny, which was the belief that it was the nation's destiny to expand its territory across the North American continent.

In contrast, the Treaty of Paris refers to agreements that ended different conflicts between nations but is not related to the Mexican-American War. The Treaty of Versailles is connected to the conclusion of World War I and does not pertain to territorial negotiations involving Mexico and the United States. The Treaty of Tordesillas, established in 1494, divided newly discovered lands outside Europe between Spain and Portugal and is unrelated to the events of the Mexican-American War or the status of Texas. Thus, the Treaty of Guadalupe Hidalgo stands out as the correct choice for ending the Mexican War and solidifying the U.S. claim to Texas.
