History of Native Americans in the Southwest

🌽History of Native Americans in the Southwest Unit 9 – US Expansion and Mexican-American War

The US rapidly expanded westward in the early 19th century, driven by Manifest Destiny and population growth. This period saw the annexation of Texas, conflicts with Native American tribes, and technological advancements that facilitated migration. The Mexican-American War (1846-1848) resulted from tensions over Texas and border disputes. The conflict ended with the Treaty of Guadalupe Hidalgo, ceding vast territories to the US and reshaping North America's political landscape.

Historical Context
