Bloomingdale Township 's history traces back to mid-1800's. When Cook County was created by the Illinois legislature in 1831, Bloomingdale, along with eight other townships, formed the south-western section of the county. Those same townships were subsequently organized into DuPage County . On November 6, 1849, Bloomingdale Township of DuPage County was officially organized. The first town meeting was held on Tuesday, April 1, 1850 in the Baptist Church building at Second and Franklin Streets in Bloomingdale. The elected officials were the Township Supervisor, Town Clerk, two Justices of the Peace, two Constables and two Commissioners of highways. The major occupation in the area was agriculture. In the year 1850, Bloomingdale Township recorded a population of 895 persons. Today, the figure surpasses 111,000. The boundaries are the same as when the township was platted in 1839. Today, however, portions of seven communities comprise the township. These include the entire Village of Bloomingdale and portions of the Villages of Addison, Carol Stream, Glendale Heights , Hanover Park, Itasca, and Roselle . Unincorporated areas of the township include the areas of Medinah, Glen Ellyn Countryside, Keeneyville and a small portion of Schaumburg . The Township is bounded on the north by Devon Avenue in Roselle, on the south by North Avenue, on the east by Rohlwing Road and on the west by Kuhn Road and consists of 36 square miles. The first Town Hall was located at 108 S. Bloomingdale Road , Bloomingdale. The Township sold this building to the Bloomingdale Park District for $1.00 by a resolution adopted by the electors of the Town of Bloomingdale at a special town meeting on May 6, 1965. It currently houses the Bloomingdale Park District Museum
