LOUISIANA PURCHASE
April 30, 1803

The purchase of the Louisiana Territory by means of the Louisiana Treaty took place in 1803. Thomas Jefferson was president at the time.

The United States bought the land from the French, who sold it for less than 3 cents per acre. Talk about a good deal.

The Louisiana Purchase expanded the territory of the United States by 828,000 square miles.

Although the purchase was signed on May 2, 1803, it was backdated to April 30.
