Which of the following occurred as a result of the Mexican American war

There are several significant outcomes of the Mexican-American War:

1. The Treaty of Guadalupe Hidalgo: This treaty, signed in 1848, ended the war and established the Rio Grande as the southern border of Texas. Mexico also ceded a vast amount of territory, including present-day California, Nevada, Utah, Arizona, New Mexico, Colorado, and parts of Wyoming, Kansas, and Oklahoma, to the United States.

2. Gadsden Purchase: In 1853, the United States acquired additional land from Mexico through the Gadsden Purchase. This territory, located in present-day southern Arizona and southwestern New Mexico, was needed to build a transcontinental railroad.

3. Increased Manifest Destiny: The Mexican-American War and the subsequent territorial acquisitions strengthened the idea of Manifest Destiny, the belief that the United States was destined to expand across the continent from the Atlantic to the Pacific. The war provided justification for westward expansion and paved the way for further territorial acquisitions.

4. Tensions over Slavery: The acquisition of new territories from Mexico reignited the debate over the expansion of slavery, leading to increased tensions between the Northern and Southern states. The issue of whether these territories would allow slavery or be free states intensified the ongoing sectional divisions that eventually led to the American Civil War.

5. Effects on Mexico: Mexico suffered significant territorial losses and economic devastation as a result of the war. Losing over half of its territory, Mexico faced challenges in rebuilding and recovering from the conflict.

6. Emergence of Prominent Military Leaders: The Mexican-American War provided a platform for several military officers who later became important figures during the Civil War. Leaders like Ulysses S. Grant, Robert E. Lee, and Stonewall Jackson gained valuable battlefield experience and sharpened their skills during this conflict.
