Born into a family of distinguished soldiers in Virginia, he had no formal education. His older brother George Rogers Clark (1775-1783) was a hero of the American Revolutionary War and a General in the Virginia Militia. When the American Revolution ended, George took his family to then-fronteir land near Louisville, Kentucky where they made their permanent home.
Following the Treaty of Paris in 1783, the Mississippi and all the land west of it were to be open to citizens of the United States and Great Britain. Britain still held Canada; Spain controlled Texas. The Louisiana Territory also belonged to Spain, and the Spanish were attempting clandestinely to take the Territory from the United States. In 1800, Spain handed over the Territory to France, ruled by the military powerhouse Napoleon. Napoleon was having trouble financing his European battles and sold it to the United States for $15 million.
President Jefferson decided that the U.S. Army must occupy, economically exploit, and control the Territory as quickly as possible. The Army had only about 3,000 troops. Jefferson appointed his personal assistant Infantry Captain Meriweather Lewis and Second Artillary Lieutenant William Clark to led the expedition, which they called the Corps of Discovery. Its purpose was “to explore...the most direct and practicable water communication across the continent, for the purpose of commerce.“ They trained fourteen soldiers for a year before seting out. |
