Mr. Dowling
The Mexican War

How did the United States accomplish Manifest Destiny?

Some Americans were in favor (Southerners) of annexing Texas while others were not (Northerners)

annex-to add on

Many were afraid that annexing Texas would cause a war with Mexico.

To get the US to agree to add Texas, Sam Houston tricked the Americans into believing the Texans would become allies with the British.

The Mexicans were not happy about this. They were also unhappy that the Americans claimed the border between Mexico and Texas was the Rio Grande. Mexico believed it was the Neuces River.

Fighting began on the disputed land in 1846

It ended in 1848 with the Treaty of Guadalupe Hidalgo. Since the Americans won the war, they gained the Mexican Cession for only $15 million. (US offered $30 million years before.)

The Mexican Cession included California, Nevada, Utah and Arizona

The United States did not look good after this "land grab". To make the US look better they purchased a tiny strip of land in Arizona and New Mexico for $10 million. This was known as the Gadsden Purchase.
