Marion County is located in the United States. The White River flows southwest through the central part of the county; it joins Eagle Creek and Fall Creek, which have dams in the county that form Eagle Creek Reservoir and Geist Reservoir, respectively. Marion County has two Indiana state parks, Fort Harrison State Park and White River State Park, as well as many municipal parks. Marion County was created on April 1, 1822, from part of the New Purchase land that had been obtained from its inhabitants, the Lenape, by the Treaty of St.
It is named after Francis Marion, a brigadier general from South Carolina in the United States War of Independence. Marion County has a consolidated city-county government, known as Unigov, in which only four municipalities retain full government autonomy (including a mayor and city council) as excluded cities. The remaining municipalities within the county are included cities and exercise very limited authority, mainly in zoning and appointing their own police departments and maintaining some of their own municipal services and city identities. They retain the capacity to collect taxes for these purposes.
Marion County has nine municipalities roughly organized in a three-by-three grid pattern. This layout can be seen below, with the top facing north. The Indianapolis City-County Council is the combined legislative body of Indianapolis and Marion County. Consolidated government, known as Unigov, was formally established in 1970 following the merger of city government with county government.
The council approves ordinances for the city and county, and makes appointments to certain boards and commissions. The Auditor, Assessor, and Treasurer form the County Board of Commissioners. The six municipalities in the north and center lean more Democratic, especially the Downtown Township that contains downtown Indianapolis, and the township of Pike in the northwest corner with an African-American majority. In contrast, the three least-populated southern municipalities with the largest Caucasian population (Decatur, Perry, and Franklin) lean more toward Republicans.
