<Tr> <Td_colspan="2"> Today part of </Td> <Td> United States Canada </Td> </Tr> <P> The Louisiana Purchase (French: Vente de la Louisiane "Sale of Louisiana") was the acquisition of the Louisiana territory (828,000 square miles or 2.14 million km2) by the United States from France in 1803 . The U.S. paid fifty million francs ($11,250,000) and a cancellation of debts worth eighteen million francs ($3,750,000) for a total of sixty - eight million francs ($15 million, equivalent to $300 million in 2016). The Louisiana territory included land from fifteen present U.S. states and two Canadian provinces . The territory contained land that forms Arkansas, Missouri, Iowa, Oklahoma, Kansas, and Nebraska; the portion of Minnesota west of the Mississippi River; a large portion of North Dakota; a large portion of South Dakota; the northeastern section of New Mexico; the northern portion of Texas; the area of Montana, Wyoming, and Colorado east of the Continental Divide; Louisiana west of the Mississippi River (plus New Orleans); and small portions of land within the present Canadian provinces of Alberta and Saskatchewan . Its non-native population was around 60,000 inhabitants, of whom half were African slaves . </P> <P> The Kingdom of France controlled the Louisiana territory from 1699 until it was ceded to Spain in 1762 . In 1800, Napoleon, then the First Consul of the French Republic, hoping to re-establish an empire in North America, regained ownership of Louisiana . However, France's failure to put down the revolt in Saint - Domingue, coupled with the prospect of renewed warfare with the United Kingdom, prompted Napoleon to sell Louisiana to the United States to fund his military . The Americans originally sought to purchase only the port city of New Orleans and its adjacent coastal lands, but quickly accepted the bargain . The Louisiana Purchase occurred during the term of the third President of the United States, Thomas Jefferson . Before the purchase was finalized, the decision faced Federalist Party opposition; they argued that it was unconstitutional to acquire any territory . Jefferson agreed that the U.S. Constitution did not contain explicit provisions for acquiring territory, but he asserted that his constitutional power to negotiate treaties was sufficient . </P> <P> Throughout the second half of the 18th century, Louisiana was a pawn on the chessboard of European politics . It was controlled by the French, who had a few small settlements along the Mississippi and other main rivers . France ceded the territory to Spain in the secret Treaty of Fontainebleau (1762). Following French defeat in the Seven Years' War, Spain gained control of the territory west of the Mississippi and the British the territory to the east of the river . </P>
