The 1804-06 exploration of the Louisiana Purchase, which broke ground for America's westward expansion.
In 1803, when the United States purchased Louisiana from France, the great expanse of this new American territory was a blank -- not only on the map but in our knowledge. President Thomas Jefferson keenly understood that the course of the nation's destiny lay westward and that a national "Voyage of Discovery" must be mounted to determine the nature and accessibility of the frontier. He commissioned his young secretary, Meriwether Lewis, to lead an intelligence -- gathering expedition from the Missouri River to the northern Pacific coast and back.
From 1804 to 1806, Lewis, accompanied by co-captain William Clark, the Shoshone guide Sacajawea, and thirty-two men, make the first trek across the Louisiana Purchase, mapping the rivers as he went, tracing the principal waterways to the sea, and establishing the American claim to the territories of Idaho, Washington, and Oregon.
