About Barrington Illinois

Barrington and its surrounding areas have a rich history dating back to the Blackhawk War of 1832. Until that time, the area that now includes Barrington had for centuries been the home to tribes of Pottawatomi and Mascouten Indians. Late that year, under the terms of a treaty signed by Chief Blackhawk, the migration of the Indians across the Mississippi River began, thus opening up vast tracts of land along the Fox River to early settlers who began moving to the area in 1834.

Barrington is a village in Cook County and Lake County, Illinois, United States. The population was 10,327 at the 2010 census. A northwest suburb of Chicago, the area features wetlands, forest preserves, parks, and horse trails in a country-suburban setting.

In the 1920s, advancements in transportation allowed wealthy families from Chicago to move into the Barrington area and build family estate homes. The location of the Village and its attractive environment appealed to those who had become wealthy during the booming 1920s. The Village’s population growth slowed during the difficult times of the 1930s and 1940s, but then resumed in the 1950s, 1960s, and 1970s as a result of the suburbanization in the Chicago area and the post–World War II baby boom.

In 2015, the Village celebrated its sesquicentennial (150th) anniversary. A series of celebratory events were held to commemorate Barrington’s milestone birthday. More can be learned here.
