What was the purpose of the Lewis and Clark Expedition?

The primary purpose of the Lewis and Clark Expedition was to explore the newly acquired Louisiana Territory. Following the Louisiana Purchase in 1803, the United States sought to understand the vast expanse of this territory, which included diverse landscapes and various Native American tribes. The expedition aimed not only to chart the land but also to gather information about the geography, natural resources, and potential routes for trade and travel.

The expedition produced valuable maps and scientific data, leading to greater knowledge about the western part of the continent. By exploring the territory and documenting their findings, Lewis and Clark significantly contributed to the westward expansion of the United States. Their journey paved the way for future explorers, settlers, and traders, helping to shape the nation's understanding and utilization of this critical region.
