Hi there! Today we are going to explore how the United States grew from coast to coast during the 1800s.
In the 1800s, many Americans believed in 'Manifest Destiny'. This was the idea that the United States was meant to expand all the way to the Pacific Ocean.
In 1803, President Thomas Jefferson bought the massive Louisiana Territory from France. This single purchase doubled the size of the United States overnight.
Jefferson sent Meriwether Lewis and William Clark to explore this new land. Guided by Sacagawea, they mapped the territory and reached the Pacific Ocean.
Let's practice our historical thinking skills. Imagine you are analyzing a historic map from 1845 that shows the United States stretching all the way to Oregon. Explain how this map connects to the concept of Manifest Destiny.
- Identify the core concept: Manifest Destiny was the belief that the U.S. was destined by fate to expand across the entire continent to the Pacific Ocean.
- Analyze the source: The map is from 1845, which is the exact time this belief was most popular among American leaders and citizens.
- Connect the evidence to the concept: By showing Oregon as part of the U.S. before it was fully settled, the map reflects the active goal of claiming lands in the West.
- Formulate your conclusion: The map is not just a geographical tool. It acts as visual proof of the Manifest Destiny mindset, showing the nation's dream of coast-to-coast growth.
