12. The Concept is……. Manifest Destiny The belief that the United States had the clear right and duty to expand to the Pacific Ocean. Goal: make the United States more powerful while educating and “saving” natives and Mexicans that lived in the west

13. Reason #1 = Texas What caused the Mexican War? Americans moved into Texas (1820’s) led by Stephen Austin. Had slaves and were protestant (both against Mexican Law) 1830: Mexico began to enforce those laws 1833: Dictator, General Santa Ana, took over Mexico. 1836: Texas won independence from Mexico. Mexico refused to recognize Texas 1845: Texas became a state = Mexico very mad.

14. Reason #2 = Manifest Destiny What else?Manifest Destiny: Belief that the United States had the right and duty to expand to the Pacific Ocean. James K. Polk supported this idea. He was elected because he promised to expand US or fight! (Either Oregon or Texas) Americans believed they were superior to Mexicans and Native Americans. Opponents worried about slavery spreading

15. Why is it a problem if the US takes land from Mexico or Britain?

16. Reason #3 = Americans in Mexican Territory And? Texas, New Mexico (Utah, Arizona, and Nevada were included), and California. Looking for inexpensive land, gold, or motivated by religion had moved to those territories. Those people wanted to become part of the US. Brigham Young led Mormons to Utah

17. The colored diagonal lines show the “disputed territory.” This is land both the US and Mexico claimed because they could not agree on the Southern border of Texas.

18. The Mexican War What happened in the War? 1846-48: Started over Texas and where the border was. Compromised with Britain over Oregon Americans under Zachary Taylor overpowered Mexico. Americans took over New Mexico and California during the war. By 1847, Americans took Mexico City. Mexico forced to agree to the Treaty of Guadalupe-Hidalgo: gave California and New Mexico to the US for $15 million (Mexican Cession).

20. What will this mean?

21. What does it mean = Manifest Destiny leads to problems over slavery!

22. War’s Aftermath What were the results of the war? 1.Manifest Destiny was achieved! 2.Reopened the slavery debate = made worse in new lands! OK? Not OK? 3.War Heroes = important leaders and experience for years to come 4.New settlers: Mormons to Utah, the Gold Rush to California (mostly from North), and more immigration (from all over) 5.People from different cultures living together = diversity!
