In this Grade 8 lesson from IMPACT California Social Studies, Chapter 11: Manifest Destiny, students examine the competing claims over the Oregon Country in the early 1800s, including the roles of the Adams-Onís Treaty, joint occupation with Great Britain, and the fur trade economy in drawing Americans westward. Students trace key events on a timeline from 1819 to 1846 and analyze how geography and economic demand for beaver pelts shaped expansion into the Pacific Northwest. The lesson also connects the Oregon boundary dispute to the 1844 presidential campaign and the broader concept of Manifest Destiny.
Section 1
Nations Compete for Oregon
In the early 1800s, four nations competed for the valuable Oregon Country. The United States, Great Britain, Spain, and Russia all claimed the territory, seeking its rich resources and access to the Pacific Ocean.
Diplomatic agreements soon simplified the rivalry. Spain gave up its claim in the 1819 Adams-Onís Treaty, and Russia later withdrew its claims. This left only the United States and Great Britain as the main rivals for the region.
Section 2
Mountain Men: Trapping and Trailblazing
In the early 1800s, beaver fur was in high demand for hats back East and in Europe. This made the fur trade a very profitable business, drawing trappers to the unexplored western wilderness.
These rugged individuals became known as mountain men. They lived a dangerous and lonely life, exploring remote streams and valleys in the Rocky Mountains to trap beavers for their valuable pelts.
Section 3
Pioneers Travel the Oregon Trail
In the 1840s, many Americans left their homes in the East due to economic hardship. They were drawn to the promise of fertile farmland in Oregon. Families packed their belongings into canvas-covered wagons and set out for a new life in the West.
These pioneers traveled for months along the 2,000-mile Oregon Trail. The journey was long and dangerous, filled with challenges like harsh weather, difficult river crossings, and deadly diseases.
Section 4
Americans Justify Westward Expansion
In the 1840s, a powerful belief known as Manifest Destiny swept across the United States. This was the idea that the nation was destined to expand its borders across the continent, from the Atlantic to the Pacific Ocean. Proponents of this idea believed it was America's obvious and inevitable mission to spread its democratic institutions and values.
This ideology provided a strong justification for Americans to settle new territories, particularly the Oregon Country. While mountain men had initially entered the region for the fur trade, Manifest Destiny inspired thousands of farmers and families to undertake the difficult journey west. They saw settling Oregon not just as an opportunity for new land, but as a patriotic duty to claim the region for the United States.
