Grade 5 · History · Free lesson

Hi there! I am Studyfin, your friendly learning buddy. Today, we will explore how the United States grew from coast to coast!

In the 1800s, many Americans believed in an idea called Manifest Destiny. This was the belief that the United States was meant to expand all the way to the Pacific Ocean. People wanted to move west to find new land, build homes, and start farms.

In 1803, the United States bought a giant piece of land from France called the Louisiana Purchase. This single purchase doubled the size of the nation! It opened up brand new areas for people to explore and settle.

To see what was in this new land, President Thomas Jefferson sent Lewis and Clark on an expedition. They mapped the land, met Native American tribes, and studied new plants and animals. Their long journey helped show people the way to the West.

Explain how the concept of Manifest Destiny and the Louisiana Purchase worked together to change the United States. Walk through the steps to connect these two historical details.

  1. First, identify the main idea of Manifest Destiny. This was the belief that the U.S. should expand its borders all the way to the Pacific Ocean.
  2. Next, look at the Louisiana Purchase of 1803. This event gave the U.S. a massive amount of new land west of the Mississippi River.
  3. Now, connect the two ideas. Manifest Destiny was the goal or the dream, while the Louisiana Purchase provided the physical land to make that dream possible.
  4. Finally, explain the result. Because of both the idea and the land, thousands of families started moving west, which completely changed the shape and size of the nation.
