Indigenous peoples lived in the area as early as 10,000 BC. In 1818, the Lenape gave their territory to the U.S. in the Treaty of St. Mary's. In 1821, Indianapolis was made as a planned city to be the new capital of Indiana. The old capital was Corydon. The city was platted by Alexander Ralston and Elias Pym Fordham on a 1-square-mile (2.6 km2) grid next to the White River. The finishing of the National and Michigan roads and the start of railroad building made the city an important transport hub. Two of the nicknames for Indianapolis (the "Crossroads of America" and "Railroad City") matches the city's history with transportation. In 1970, Indianapolis and Marion County were combined. This system is called Unigov. The city is led by an elected 25-member city-county council led by the mayor.
