The Louisiana Purchase was a land deal made in 1803, in which the United States purchased 828,000 square miles (2,144,510 km²) of land west of the Mississippi River from France for $15 million, or an average of three cents per acre. The purchase nearly doubled the territorial size of the United States and fostered the westward expansion of the young republic.
