Lesson 1: The West

In this Grade 8 lesson from America: History of Our Nation, students explore the concept of the western frontier in the early 1800s, identifying key destinations such as Oregon Country and the Southwest's Spanish Borderlands. Students examine the distinct culture of the Southwest, shaped by Spanish and Mexican rule, mercantilism, and the blending of peninsulares, creoles, and mestizos. The lesson also introduces the idea of Manifest Destiny and its role in driving American westward expansion beyond the Great Plains.

Section 1

Settlers Cross Plains to Reach Western Frontiers

Early 1800s Americans traveled across the Great Plains toward Oregon Country in the Northwest or Mexican lands in the Southwest, seeking better farming opportunities beyond Mississippi River territories.

Section 2

Cultures Blend to Create Southwestern Identity

Spanish settlers, Native Americans, and Africans intermarried in the Southwest, creating distinct mestizo culture. They exchanged language, religion, foods, and building techniques like adobe architecture.

Section 3

Mexico Transforms Land Policies After Independence

After gaining independence in 1821, Mexico allowed foreign trade and distributed land grants to rancheros and some American settlers, unlike Spain which restricted trade and limited land ownership.

Section 4

Americans Embrace Manifest Destiny Vision

By the 1840s, many Americans believed the United States was destined to expand from Atlantic to Pacific. This powerful concept drove westward expansion and shaped America's approach to territorial growth.
