The Town of Cicero is one of the oldest and largest municipalities in the State of Illinois and the only incorporated town in Cook County. It bears the name of the great Roman statesman of the First Century B.C., Marcus Tullius Cicero.

Cicero was one of the greatest statesmen of Rome and an advocate of constitutional government. He died in the political turmoil which followed the assassination of Julius Caesar, but his writings and beliefs survived. Centuries later, the principles Cicero espoused would flourish again in a young republic with a new constitution, capitol and senate, the United States of America.

Illinois, part of the old Northwest Territory which the United States had acquired from Great Britain in 1783, joined the Union as the 21st state in 1818. Most of the early Illinoisans were from the South, where counties were the basis of local government and so the new state was divided into counties. Cook County was established in 1831, comprising what is today Cook, DuPage, Iroquois, Lake, McHenry and Will Counties.
