Until 1861, municipal elections were held in March. In that year, legislation changed them to April. In 1869, however, election time was changed to November, and terms expiring in April of that year were lengthened.

In 1875, the election day was moved back to April by the city's vote to operate under the Cities and Villages Act of 1872. Lester L. Bond was the acting mayor when Joseph Medill left to a tour around Europe. Thomas Hoyne won election as mayor, but could not become the mayor so the election became a void. As of 1995, no mayor can run for a political party, they are considered as nonpartisans.
