On May 14, 1804, Captain Meriwether Lewis and Second Lieutenant William Clark embarked on the nation’s first expedition to explore the Western U.S. all the way to the Pacific coast. The expedition, commissioned by President Jefferson following the Louisiana Purchase, began in St. Louis and lasted from May 1804 until September 1806. The main objectives of the expedition were to explore the newly acquired territory, develop a travel route, and establish a presence in the area.
