Manifest Destiny and the Wagon Trains
In the 1840s, Americans believed in Manifest Destiny—the idea that the U.S. was meant to expand to the Pacific Ocean.
Thousands of families packed their lives into covered wagons to travel west on the Oregon Trail.
The journey was dangerous and took months. Pioneers faced disease, harsh weather, and difficult terrain as they crossed the plains and mountains to start new lives in the West.
