Which of the following was a result of the Mexican-American war?

There were several results of the Mexican-American War. Some of the key outcomes include:

1. Treaty of Guadalupe Hidalgo: This treaty, signed in 1848, officially ended the war. Under the terms of the treaty, Mexico ceded vast territories to the United States, including California, Nevada, Utah, Arizona, New Mexico, Wyoming, and parts of Colorado and Oklahoma. This acquisition nearly doubled the size of the United States.

2. Rio Grande as the Border: The war confirmed the Rio Grande as the official boundary between Texas and Mexico, resolving a longstanding territorial dispute.

3. Loss of Mexican Territory and Population: Mexico lost approximately 55 percent of its pre-war territory, which included some of its most resource-rich regions. The war also led to a significant loss of population in Mexico, as many Mexican citizens living in ceded territories chose to become U.S. citizens or moved back to Mexico.

4. Expansion of Slavery Debate: The acquisition of new territories reignited the debate over the expansion of slavery, as some areas acquired from Mexico were open to slavery. This dispute eventually contributed to the tensions leading up to the American Civil War.

5. Strengthening of the United States: The war solidified the United States as a continental nation, expanding its territory from the Atlantic to the Pacific. It also confirmed U.S. military strength, as American forces defeated a more prominent Mexican army.

6. Long-term Tensions with Mexico: The war left lasting animosity between the United States and Mexico, with resentment still lingering in some sections of Mexican society. This animosity has occasionally strained U.S.-Mexico relations throughout history.
