Unigov is the colloquial name adopted by the city of Indianapolis, Indiana to describe its consolidated city–county government.  By an act of the Indiana General Assembly, Indianapolis consolidated with the government of Marion County in 1970.  Within Unigov are eleven "included towns".  Under state law Indiana Code 36-3-1-4 sec. 4(a)(2)), included towns are legally part of the Consolidated City of Indianapolis and are fully subject to the laws and control of the government of Indianapolis.  Four other municipalities in Marion County are not part of the Indianapolis government ("excluded cities and towns"), but receive county-level services from Unigov and are represented by the Indianapolis City–County Council and mayor.

During the American Civil War, Indianapolis, the state capital of Indiana, was a major base of support for the Union.  Governor Oliver P. Morton, a major supporter of President Abraham Lincoln, quickly made Indianapolis a gathering place to organize and train troops for the Union army.  The city became a major railroad hub for troop transport to Confederate lands, and therefore had military importance.  Twenty-four military camps were established in the vicinity of Indianapolis.  Camp Morton, the initial mustering ground to organize and train the state's Union volunteers in 1861, was designated as a major prisoner-of-war camp for captured Confederate soldiers in 1862.  In addition to military camps, a state-owned arsenal was established in the city in 1861, and a federal arsenal in 1862.  A Soldiers' Home and a Ladies' Home were established in Indianapolis to house and feed Union soldiers and their families as they passed through the city.  Indianapolis residents also supported the Union cause by providing soldiers with food, clothing, equipment, and supplies, despite rising prices and wartime hardships, such as food and clothing shortages.  Local doctors aided the sick, some area women provided nursing care, and Indianapolis City Hospital tended to wounded soldiers.  Indianapolis sent an estimated 4,000 men into military service; an estimated 700 died during the war.  Indianapolis's Crown Hill National Cemetery was established as one of two national military cemeteries established in Indiana in 1866.
