Jefferson, Lewis, and the Western Plan

In 1803, the United States changed in a single stroke. Thomas Jefferson bought the Louisiana Territory from France for fifteen million dollars, doubling the size of the nation and giving it control of the Mississippi River system and New Orleans. He believed the country now had a chance to become a continental republic, not a small nation pressed against the Atlantic coast.

Jefferson did not want this new land to remain a blank space on the map. He wanted to know its rivers, plants, animals, peoples, and trading routes, and he still hoped there might be a practical route to the Pacific. He also understood that Britain, Spain, and many Native nations already had strong interests in the West, so exploration was not just about science. It was also about power, trade, and the future direction of the United States.

For that task, Jefferson chose Meriwether Lewis. Lewis was not the most polished scholar in America, but he was strong, disciplined, brave, and deeply familiar with the frontier. Jefferson trusted him completely, first as a private secretary in Washington and then as the leader of a western expedition that would become one of the most important journeys in American history.

As Jefferson’s secretary, Lewis learned how government worked at the highest level. He lived in close contact with the president, discussed western strategy, and absorbed Jefferson’s wide interests in geography, natural science, and Native cultures. Jefferson also noticed that Lewis sometimes suffered from dark moods, but he still saw in him the rare mix of toughness and intelligence needed for a journey into the unknown.
