How was the territory of Louisiana divided?

Louisiana Territory was formed out of the Indiana Territory-administered District of Louisiana, which consisted of all Louisiana Purchase lands north of the 33rd parallel. The 33rd parallel now forms the southern border of Arkansas and the northern border of Louisiana. The territory's predecessor, the District of Louisiana, as well as the District of Orleans, were formed from the lands acquired by the United States in the Louisiana Purchase, in which colonial Louisiana was purchased from France.
