who were the first known inhabitants in louisiana
History of Louisiana The history of the territory that is now Louisiana began roughly 10,000 years ago. The first traces of permanent settlement, ushering in the Archaic period, appear about 5,500 years ago (Mound Builders).
Louisiana Purchase 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.[1]
