Today's Lesson

In this lesson, we'll explore westward expansion and trails. Understanding history and society helps us become informed citizens.

Westward expansion was the movement of Americans from the East Coast toward the Pacific Ocean in the 1800s. Reasons included: desire for land and resources, discovery of gold, belief in Manifest Destiny (the idea that America should stretch from coast to coast), and new opportunities. The Louisiana Purchase (1803) doubled U.S. territory. Trails like the Oregon Trail brought settlers west. Expansion had major impacts: growth and opportunity for some, but displacement and harm to Native Americans. Understanding expansion shows both progress and its costs.

As you work through today's material, pay attention to the examples and try to identify the patterns or strategies being used. This will help you apply these concepts to new problems.
