Migrating to the West
Settling the Spanish Borderlands
Main Idea: In the Southwest in the early 1800s, conflict between Spanish settlers and Native
Americans was frequent and destructive. However, New Mexico and California eventually gained
stability, resulting in high populations and economic growth.
Americans Look Westward
Main Idea: By 1821, American expansionists soon began to covet New Mexico, Texas, and
California. Thinly settled but rich in resources, the three provinces had great appeal for American
pioneers.
The Journey Westward
Main Idea: Following John C. Frémont’s vivid and romantic reports from his western expedition,
the overland trails drew thousands of settlers west to California and Oregon.

Texas and the Mexican-American War
Texas Wins Independence
Main Idea: Tensions grew between American settlers and the Mexican government. Following a
rebellion against Mexican rule, Texans declared their independence and adopted a republican
constitution.
Americans Debate Expansion
Main Idea: Sam Houston asked that the United States annex Texas, but many in Congress
were opposed because of the impact this would have in the slavery debate.
The Mexican-American War
Main Idea: Texas claimed the land south and west of the Nueces River as far as the Rio Grande
as its own. Outraged, the Mexicans refused to recognize the annexation. The war that followed
resulted in an American victory.

Effects of Territorial Expansion
America Achieves Manifest Destiny
Main Idea: The United States finally achieved Manifest Destiny after its victory in the MexicanAmerican War. Yet, the long-term effects of the war served to highlight growing differences
between North and South and set the stage for future conflict.
The California Gold Rush
Main Idea: To most Americans, the new lands in the West seemed too distant for rapid
settlement. But in early 1848, sawmill workers found flecks of gold in the American River east of
Sacramento, California, starting a mass migration to the region.
Effects of the Gold Rush
Main Idea: The rapid settlement of California had unforeseen consequences on both the territory
and the nation. The most immediate effects were felt by the people who already lived there.
Among these effects were discrimination and violence towards Indians and Mexicans.
