Louisiana Purchase, 1803. 1  The Louisiana Purchase encompassed 530,000,000 acres of territory in North America that the United States purchased from France in 1803 for $15 million.
The Louisiana Purchase would have cost $233 million in 2011 dollars. That's around 42 cents per acre. Some historians claim that Napoleon had no right to sell the Louisiana Territory to the United States. The issue of slavery in the western lands of the Louisiana Purchase became a major issue in later years and part of the cause of the American Civil War. The land had been owned by Spain for a while before they sold it back to France in 1800.
