William Clark

William Clark is famous as one of the leaders on the Lewis and Clark Expedition, but he was also a soldier, a politician, and Indian agent. When he was a young boy, America became an independent country and by the time he died, the young country had expanded beyond the Mississippi and more than doubled in size. William served in the Army, explored and mapped new territory, served as governor of the Missouri Territory, and worked to keep the peace between Native Americans and new American settlers moving west as the country expanded.
