Barrington is a suburban village in Cook County and Lake County, Illinois, United States. The population was 10,327 at the 2010 census. Located approximately 32 miles (51 km) northwest of Chicago, the area features wetlands, forest preserves, parks, and horse trails in a country-suburban setting.
The Barrington area ZIP code, 60010, is the seventh-wealthiest ZIP code in the United States among areas with a population of 20,000 or more.
Barrington is part of the Chicago metropolitan area and serves as the hub of activity for the surrounding 90-square-mile (230 km2) region which consists of six independent villages including North Barrington, South Barrington, Barrington Hills, Lake Barrington and Tower Lakes, as well as small portions of Carpentersville, Deer Park, Hoffman Estates, Fox River Grove, Port Barrington and Inverness. The village's motto is "a great place to live, work, and play!"
The original settlers of the Barrington area were the indigenous peoples of the Native American Prairie Potawatomi or Mascoutin tribes, which later divided into the Potawatomi, Chippewa, and Ottawa tribes. Many local roads still in use today, including Algonquin Road, Rand Road, Higgins Road, and St. Charles Road, were originally Native American trails. For many years, Barrington was considered part of the Northwest Territory, then the Illinois Territory.
By treaty dated September 26, 1833, ending the Black Hawk War, the Chippewa, Ottawa and Potawatomi tribes ceded to the United States all lands from the west shore of Lake Michigan west to the area that the Winnebago tribe ceded in 1832, north to the area that the Menominees had previously ceded to the United States, and south to the area previously ceded by an 1829 treaty at Prairie du Chien, a total of approximately 5,000,000 acres (20,000 km2). Through this treaty, the Sacs, Fox, Winnebago, Chippewa, Ottawa and Pottawatomi tribes ceded all title to the area east of the Mississippi River. Between 1833 and 1835, the U.S. government paid approximately $100,000 in annuities and grants to the Potawatomi, Ottawa, and Chippewa tribes, presumably as payment for the land.
Following this treaty, pioneers traveling from Troy, New York, via Fort Dearborn (now the city of Chicago) to live in Cuba Township in Lake County.
