Who were the leaders of the Lewis and Clark expedition, commissioned by President Jefferson?

The Lewis and Clark expedition, officially known as the Corps of Discovery, was led by Meriwether Lewis and William Clark. Commissioned by President Thomas Jefferson in 1803, the expedition aimed to explore the newly acquired Louisiana Territory and to establish trade and sovereignty over the Native American tribes along the way. Lewis was Jefferson's personal secretary and had a background in military service and natural sciences, which made him well-suited for the task. Clark, a skilled frontiersman and cartographer, joined Lewis as the co-leader of the expedition.

The collaboration between these two leaders was instrumental in the success of the journey, as they worked together to document new species of plants and animals, map the regions they traversed, and establish diplomatic relations with various Native American tribes. Their observations contributed significantly to American geography and helped the U.S. expand its understanding of the westward regions of the continent.
