The Louisiana Purchase
Under the direction of President Thomas Jefferson, the Louisiana Purchase of 1803 — the largest single land deal in the history of the United States — doubled the size of the young nation. Napolean Bonaparte of France, whose dream for an empire in America had been dashed, sold the territory of 600 million acres for $15 million, or approximately 4˘ per acre.
The acquisition, acquired as a result of the successful negotiating efforts of Robert R. Livingston, the United States Minister at Paris, and special envoy James Monroe, eventually became the following states or parts of states: Louisiana, Arkansas, Missouri, Iowa, North Dakota, South Dakota, Nebraska, Kansas, Wyoming, Minnesota, Oklahoma, Colorado, and Montana.
The original treaty is in the National Archives of the United States.
