President Thomas Jefferson commissioned the expedition after the Louisiana Purchase in 1803. Lewis and Clark were given the mission to explore the newly acquired territory, establish an American presence in the area, and find a practical route to the west. Along the way, they were to also study the region’s plant and animal life and establish trade with Native American tribes. They were accompanied by Sacagawea, a Shoshone woman who helped act as an interpreter during the journey. In November 1805, the group arrived to the Pacific Ocean.

Almost two and a half years after they began their journey, the Lewis and Clark Expedition finally returned to St. Louis on September 23, 1806 with a wealth of information about the new lands.
