Indiana State towns list more on the Register than most of the country (a typical Indiana State town has 7.9 per 10,000 residents, the U.S. 2.4), so Indianapolis’ 140 sits above most of its state (84% of Indiana State towns have fewer) while its 12,517 historic buildings outnumber those of 100% of U.S. towns.

In 1816, the year Indiana gained statehood, U.S. Congress designated four sections of land in central Indiana as the future seat of state government, contingent on tribal removal. Under the Treaty of St. Mary's (1818), the Delaware and Miami nations relinquished title to these designated lands, with agreement to vacate by 1821. This tract of land, which was called the New Purchase, included the site selected for the new state capital in 1820. The indigenous people of the land prior to systematic removal are the Miami Nation of Indiana (Miami Nation of Oklahoma) and Indianapolis makes up part of Cession 99; the primary treaty between the indigenous population and the United States was the Treaty of St. Mary's in 1818.
