Louisiana (New France) - Nature and Geography

Nature and Geography

In the 18th century, Louisiana included most of the Mississippi River Valley, from what is now the Midwestern United States south to the coast of the Gulf of Mexico. Demarcating the exact territory is difficult as it did not have formal, defined borders in the modern sense. Within this vast territory, only two areas saw substantial French settlement: Upper Louisiana (French: Haute-Louisiane), also known as the Illinois Country (French: Pays des Illinois), which consisted of settlements in what are now the states of Missouri, Illinois, and Indiana; and Lower Louisiana, which comprised parts of the modern states of Louisiana, Arkansas, Mississippi, and Alabama. Both areas were dominated numerically by Native American tribes.

"At times, fewer than two hundred soldiers were assigned to all of the colony, on both sides of the Mississippi. In the mid-1720s, Louisiana had some 2,500 French, plus 1,500 slaves. In contrast, Louisiana Indians numbered well over 35,000."

Generally speaking, Louisiana bordered the Great Lakes, particularly Lake Michigan and Lake Erie towards the north. On the east, the French colony was separated by the Appalachian Mountains from the Thirteen British Colonies. The Rocky Mountains region marked the western extent of the French claim. Louisiana's southern border was formed by the Gulf of Mexico, which served as the port for the colony.

The colony was mostly flat, which aided European movement through the territory. Its average elevation is less than 1,000 metres. The territory becomes more mountainous towards the west, with the notable exception of the Ozark Mountains, which are located in the mid-south.
