The history of Chicago's city government dates back to March 4, 1837 when the town of Chicago, with a population of approximately 4,006, was granted a city charter by the Illinois state legislature. Seven hundred and nine (709) of Chicago's citizens voted in the first major election on May 2, 1837, selecting a mayor, treasurer, city clerk and common council. A census, taken by the city a few months after the charter was granted, revealed, in part, that there were 398 dwellings, 5 churches, 26 liquor dispensaries, 10 taverns, 19 groceries, 17 law offices and 3 drug stores in the newly chartered city.
The Common Council, the predecessor of the present City Council, was comprised of ten (10) aldermen representing the city's six (6) wards. At that time, each ward had two (2) aldermen, with the exception of the 3rd and 5th wards which had only one each.
The aldermanic term was a (1) year in length and city-wide elections were held on the first Tuesday in March. Eligible voters cast their votes orally until the Common Council changed the practice on February 10, 1840 requiring ballot boxes and election judges.
During the early years, the Common Council was called upon to confront many issues. The complete devastation caused by the great Chicago fire on October 8, 1871 was the most significant crisis the city government ever faced. Overnight, flames swept through the streets causing three (300) hundred deaths and rendering ninety-four (94,000) thousand people homeless. However, the city by the river of the Wild Onion rose from the ashes. Twenty (20) years after the Great Fire, not a scar remained of the calamity. The city approached a million and a quarter (102,50,000) in population and entertained the world at the Columbian Exposition in 1893. Indeed, Chicago, growing in population and prosperity, would go on to become one of the world's greatest cities during the twentieth century (20th).
Historically, 44 men and one (1) women collectively served 80 terms of office as mayor, beginning with the city's first mayor, William B. Ogden (1837 - 1838), and ending with the current mayor, Richard M. Daley.

Sixth City Hall (1885-1908): Chicago and Cook County once again joined efforts to construct a dual purpose building located at LaSalle, Washington, Clark and Randolph (the present site). A gas explosion on the County side in 1905 led to the demolition of the entire building and paved the way for the construction of the present City Hall.

Seventh City Hall (1911-present): The seventh and present City Hall and County Building, bounded by LaSalle, Randolph, Clark, and Washington, went under construction in 1906. Construction was begun on the County portion (east half facing Clark) in January of 1906. Construction on the City Hall portion (west half facing LaSalle) was begun on April 15, 1909. The entire stucture, built in accordance to the Burnham Architectural Plan, was completed in 1911.
