[Footnote: This territory was created in 1787, and included all the public land north of the Ohio. It embraced the present States of Michigan, Ohio, Indiana, Illinois, Wisconsin, and part of Minnesota. It was a part of New France before the French authority ceased in 1763. The British held possession for twenty years, when the country was ceded to the United States (see Map of VIth Epoch, and p. 146)] LOUISIANA, the eighteenth State, was admitted to the Union April 8, 1812. The territory was named in honor of Louis XIV, king of France. The French explored the river Mississippi to the sea in 1682 (see p. 34), but their first settlement was made by Iberville at Biloxi, near its mouth, in 1699. New Orleans was founded in 1718. [Footnote: The colony was granted to the great Mississippi Company, organized by John Law, at Paris, for the purpose of settling and deriving profit from the French possessions in North America. When this bubble burst, the French crown resumed the country. (See Brief History of France, p. 176.)] The territory was ceded to Spain in 1762, but in 1800 was receded to France. When the United States purchased it (see p. 155), Louisiana included all the region north and west between the Mississippi and the Pacific (except those portions then occupied by Spain: see California) and north to the British possessions. In 1804, this region was divided into two parts--the territory of Orleans, which included the present State of Louisiana, and the district of Louisiana, which comprised the remainder. The former was admitted to the Union as Louisiana, and the name of the latter changed to Missouri. INDIANA, the nineteenth State, was admitted to the Union December 11, 1816. The name is derived from the word Indian. The exact date of the first settlement is undetermined. When Ohio was taken from the Northwestern Territory, the remainder was called Indiana. It was reduced to its present limits in 1809, and was the second State admitted from the Northwestern Territory. After the Indian difficulties which hindered its early development had subsided, its growth was very rapid. Between 1810 and 1820, its population increased five hundred per cent.
