 In 1809, after the Indiana Territory was divided to create the Illinois Territory, Congress further altered the makeup of the territorial legislature.Voters in the Indiana Territory would continue to elect members to its House of Representatives; however, they were also granted permission for the first time to elect members to its Legislative Council (upper house).The major political issue in Indiana's territorial history was slavery; however, there were others, including Indian affairs, the formation of northern and western territories from portions of the Indiana Territory, concerns about the lack of territorial self-government and representation in Congress, and ongoing criticisms of Harrison's actions at territorial governor.
