With the 1803 purchase of Louisiana from the French, the U.S. more than doubled its size with land to the west of the Mississippi River. Thomas Jefferson was able to advance his vision to expand an America dedicated to liberty to the western edge of the continent. After Lewis and Clark explored the land, many settlers began to venture beyond the Mississippi River. For Native American tribes in the West, liberty as they knew it would begin to fade away. Lewis and Clark wintered in a Mandan village near present-day Washburn, North Dakota. Sakakawea joined the Corps of Discovery in North Dakota.
