The Quad Cities is a region of four counties in northwest Illinois and Southeastern Iowa. The urban core consists of five principal cities: Davenport and Bettendorf in Iowa, and Rock Island, Moline, and East Moline in Illinois. These cities are the center of the Quad Cities Metropolitan Area, which, as of 2013, had a population estimate of 383,781 and a CSA (Combined Statistical Area) population of 474,937, making it the 90th largest CSA in the nation.

Before European settlers came to inhabit the Quad Cities, the confluence of rivers had attracted many varying cultures of indigenous peoples, who used the waterways and riverbanks for their settlements for thousands of years. At the time of European encounter, it was a home and principal trading place of the Sauk and Fox tribes of Native Americans. Saukenuk was the principal village of the Sauk tribe and birthplace of its 19th-century war chief, Black Hawk. In 1832, Sauk chief Keokuk and General Winfield Scott signed a treaty in Davenport after the US defeated the Sauk and their allies in the Black Hawk War. The treaty resulted in the Native Americans' ceding 6 million acres (24,000 km²) of land to the United States in exchange for a much smaller reservation elsewhere. Black Hawk State Historic Site in Rock Island preserves part of historic Saukenuk and is listed on the National Register of Historic Places.
The history of urban settlements in the Quad-Cities was stimulated by riverboat traffic. For fourteen miles (21 km) between LeClaire, Iowa, and Rock Island, the Mississippi River flowed across a series of finger-like rock projections protruding from either bank. These rapids were difficult for steamboats to traverse. As demand for river-based transportation increased along the upper Mississippi, the navigability of the river throughout the "Rock Island Rapids" became a greater concern. Over time, a minor industry grew up in the area to meet the steamboats' needs. Boats needed rest areas to stop before encountering the rapids, places to hire expert pilots such as Phillip Suiter, who was the first licensed pilot on the upper Mississippi River, to guide the boat through the rocky waters, or, when the water was low, places where goods could be removed and transported by wagon on land past the Rapids. (Today, the troublesome rocks are submerged six feet underwater by a lake formed by two locks and dams.)
As the Industrial Revolution developed in the United States, many enterprising industrialists looked to the Mississippi River as a promising source of water power. The combination of energy and easy access to river transportation attracted entrepreneurs and industrialists to the Quad Cities for development. In 1848, John Deere moved his plough business to Moline. His business was incorporated as Deere & Company in 1868. Deere & Company is the largest employer today in the Quad Cities.
The first railroad bridge built across the Mississippi River connected Davenport and Rock Island in 1856. It was built by the Rock Island Railroad Company, and replaced the slow seasonal ferry service and winter ice bridges as the primary modes of transportation across the river. Steamboaters saw the nationwide railroads as a threat to their business. On May 6, 1856, just weeks after completion of the bridge, an angry steamboater crashed the Effie Afton into it. John Hurd, the owner of the Effie Afton, filed a lawsuit against The Rock Island Railroad Company. The Rock Island Railroad Company selected Abraham Lincoln as their trial lawyer and won after he took the case to the US Supreme Court. Phillip Suiter was one of his expert witnesses. It was a pivotal trial in Lincoln's career.
Evolution of an identity
After the Civil War, the region began to gain a common identity. The river towns that were thoughtfully planned and competently led flourished, while other settlements, usually get-rich-quick schemes for speculators, failed to pan out. By World War I, the towns of Davenport, Rock Island, and Moline had begun to style themselves as the Tri-Cities, a cluster of three more-or-less equally sized river communities growing around the small bend of the Mississippi River where it flows west. But with the growth of Rock Island County, during the 1930s the term Quad Cities came into vogue, as East Moline was given "equal status". Despite the fact that the region had earned the name "Quad Cities", the National Basketball Association had a franchise in Moline, Illinois from 1946 to 1951 called the Tri-Cities Blackhawks. Then, with the opening of an Alcoa plant East of Davenport in 1948, the town of Bettendorf underwent so much growth that many people in the community discussed the adoption of the name Quint Cities. And indeed, eventually Bettendorf passed East Moline in size. But by this time, the name "Quad Cities" had become known well beyond the area, and "Quint Cities" never caught on, despite the efforts of WOC-TV (as KWQC-TV was then called) and others.
Beginning in the late 1970s, economic conditions caused major industrial restructuring, which disrupted the basis of the region's economy. The major companies, agricultural manufacturers, ceased or scaled back operations in the Quad Cities. Factories which closed included International Harvester in Rock Island and Case IH in Bettendorf. Moline-based John Deere cut its labor headcount by one half. Later in the 1980s, Caterpillar Inc. closed its factories at Mount Joy and Bettendorf.
Since the 1990s, the Quad Cities governments, businesses, non-profits and residents have worked hard to redevelop the region. They have achieved national attention for their accomplishments.
Examples of revitalization and rebirth:
- Davenport's River Renaissance (a downtown revitalization project that includes a River Music History Center), an ag-tech venture capital campus, and the Figge Art Museum opened or were completed during the first decade of the 21st century.
- Moline has invested in what was once a robust downtown. The "John Deere Commons" and i wireless Center (formerly "The MARK of the Quad Cities") both opened during the 1990s.
- In 2007, Davenport and Rock Island competed for and won the title of "most livable small city" from the National Council of Mayors, based upon an unfunded proposal called RiverVision.
- In 2008 Bettendorf was ranked by CNN as one of the ten best places to buy a house in the United States.
- In 2010, The Quad Cities was named "The Most Affordable Metro" by Forbes magazine.
- In 2012, Davenport housing market ranked 2nd in the nation beating the housing bubble, due to its lack of foreclosures and their low unemployment.
- In 2012, the Quad Cities Metropolitan Area was ranked among the fastest-growing areas in the nation in the growth of high-tech jobs.
- In 2012, the Quad Cities was named the "2012 All American City"
- In 2013, Modern Woodman Park was voted the best Minor League Ballpark in America.
The Quad Cities are located at the confluence of the Rock and Mississippi rivers, approximately 140 miles (230 km) west of Chicago, and is the largest metropolitan area along the Mississippi River between Minneapolis–Saint Paul and the St. Louis metropolitan area. Interstate 80 crosses the Mississippi River here. The Quad Cities area is distinctive because the Mississippi River flows from east to west as it passes through the heart of the area; the Iowa cities of Davenport and Bettendorf are located due north of Rock Island and Moline, respectively.
The Quad Cities area is one where the telephone companies cooperate with regional phone calls. Iowa and Illinois have different area codes (563 and 309 respectively), yet most calls originating and terminating within the core urban area are placed without long-distance charges by dialing just a 7-digit number. This helps the bi-state area promote itself as a single community, "joined by a river."
The Quad Cities Metropolitan Area consists of three counties: Scott County in Iowa, Rock Island County, and western Henry County county in Illinois. The Quad City metro population is 272,000. The Quad Cities Metropolitan Area is also considered part of the Great Lakes Megalopolis.

Amtrak currently does not serve the Quad Cities. The closest station is about 50 miles (80 km) away in Galesburg, Illinois. In 2008, the two current United States Senators from Iowa, Tom Harkin and Chuck Grassley, Illinois Senator Dick Durbin, and former Senator Barack Obama sent a letter to Amtrak asking them to begin plans to bring rail service to the Quad Cities. In October 2010, a $230 million federal fund was announced that will bring Amtrak service to the Quad Cities, with a new line running from Moline to Chicago. They hope to have the line completed in 2015, and offer two round trips daily to Chicago. In December 2011, the federal government awarded $177 million in funding for the Amtrak connection. It will establish passenger rail for the first time since the 1970s.
The Quad Cities are served by the Quad City International Airport, Illinois' third-busiest airport, located in Moline.
