===Proposed mergers===
Over the years, several communities in the Quad Cities region have proposed or performed mergers. As it grew, Davenport annexed the communities of Rockingham, Nahant, Probstei, East Davenport, Oakdale, Cawiezeel, Blackhawk, Mt. Joy, Green Tree, and others. Bettendorf annexed portions of Pleasant Valley in the 1970s. In 1987, Rock Island, Moline, East Moline, Milan, Carbon Cliff, Hampton, Coal Valley and Silvis considered a super-city merger which would have seen the Illinois cities become the second-largest city in the state,<ref>{{cite web |last1=Schmeltzer |first1=John |title=Quad Cities Toying with Supercity Idea |url=https://www.chicagotribune.com/news/ct-xpm-1987-08-19-8703050010-story.html |website=Chicago Tribune |access-date=11 August 2019 |date=1987-08-19}}</ref> but the proposal ultimately failed.
