County is located in the U.S. State of Indiana.
Census 2010 recorded a population of 903,393,
making it the largest county in the state and 55th
most populated county in the country, greater than
the population of six states. The county seat is
Indianapolis, the state capital and largest city.
Marion County is consolidated with Indianapolis
through an arrangement known as Unigov.
Marion County is included in the
Indianapolis-Carmel-Anderson, IN Metropolitan
Marion County was created on April 1, 1822, from
part of the so-called "New Purchase" lands that
had been obtained by the Treaty of St. Mary's; the
Lenape had previously occupied the area. It is
named for Francis Marion, a Brigadier General from
South Carolina in the American Revolutionary War.
The state capital was moved to Indianapolis in
Marion County from Corydon on January 10, 1825.
This began a period of rapid growth in population.
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 towns" and exercise very
limited authority, mainly in zoning and appointing
their own police departments and maintaining some
of their own municipal services and town
identities. They retain the ability to levy taxes
for these purposes. Since many of these included
towns were and remain fairly wealthy and
influential within the county, they can still have
considerable unofficial clout. Likewise, some
neighborhoods that had already been formally
incorporated into Indianapolis (such as Broad
Ripple) possess similar influence.
