What was the main purpose of the Lewis and Clark Expedition?

The main purpose of the Lewis and Clark Expedition was to explore and map the newly acquired western territories of the United States. Commissioned by President Thomas Jefferson after the Louisiana Purchase in 1803, the expedition aimed to gather detailed information about the geography, resources, and inhabitants of the vast lands acquired from France.

Lewis and Clark were tasked with finding a water route to the Pacific Ocean, documenting the diverse ecosystems they encountered, and studying the cultures of Native American tribes in the region. Their findings significantly contributed to the United States' understanding of the West and laid the groundwork for future exploration, settlement, and expansion. The expedition's successful mapping of this territory was essential for promoting further migration and economic development in the years to come.
