Effective October 1, 1804, the Louisiana Purchase lands were divided into the Territory of Orleans (most of which would later become the state of Louisiana) and the District of Louisiana. Since the newly acquired District of Louisiana lacked an established local government, it was placed temporarily under the jurisdiction of the Indiana Territory, allowing the governor and judicial system there to oversee administrative and legal matters until a permanent structure could be implemented.
