LOUISIANA PURCHASE. LOUISIANA PURCHASE. A watershed event in American history, the purchase of the Louisiana Territory from France in 1803 nearly doubled the land mass of the young nation: for a purchase price of $15 million, the United States increased its size by some 828,000 square miles.
Louisiana Purchase summary: The United States bought 828,000 square miles of land from France in 1803.
