What was the significant territorial outcome of the Mexican War?

• A. The annexation of Texas
• B. The nation’s borders extended to the Pacific Ocean
• C. The acquisition of Florida
• D. Control over California

Answer: (B)

The annexation of the territory that extended the nation's borders to the Pacific Ocean is a significant outcome of the Mexican War. This war, fought between 1846 and 1848, resulted in the United States acquiring a vast expanse of land through the Treaty of Guadalupe Hidalgo. This treaty not only confirmed Texas's annexation but also ceded a large portion of Mexico's northern territories, including present-day California, Nevada, Utah, Arizona, and parts of Colorado and New Mexico. This territorial expansion fulfilled the idea of Manifest Destiny—the belief that the United States was destined to expand across the North American continent—effectively giving the nation access to the Pacific Ocean. This directly influenced the economic, political, and demographic landscape of the country, laying the groundwork for westward expansion and settlement.
