geography Maturity 11-13 Next article →

The Quad Cities is a major metropolitan region in the United States. It is located within the Mississippi River Valley. The area consists of five distinct cities spanning two different states. Davenport and Bettendorf are located in southeastern Iowa. Rock Island, Moline, and East Moline are located in northwestern Illinois.

This region is the largest metropolitan area along the Mississippi River between St. Louis and Minneapolis–Saint Paul. It is also considered a part of the Great Lakes Megalopolis. As of 2023, the metropolitan area had a population estimate of 467,817. The Combined Statistical Area (CSA) population was slightly higher at 474,019. This makes it the 90th-largest CSA in the nation.

Long before European settlers arrived, the confluence of rivers was a vital location. Many different indigenous cultures lived there for thousands of years. They used the riverbanks and waterways for their many settlements. At the time of European contact, the Sauk and Fox tribes lived there. The Sauk tribe had a principal village called Saukenuk. This was the birthplace of the 19th-century war chief, Black Hawk.

In 1832, the US defeated the Sauk and their allies in the Black Hawk War. Following this, Sauk chief Keokuk signed a treaty in Davenport. This treaty resulted in the Native Americans ceding their land to the United States. Today, the Black Hawk State Historic Site in Rock Island preserves part of the historic Saukenuk area.

Early urban growth was driven by riverboat traffic on the Mississippi. Between LeClaire, Iowa, and Rock Island, the river contained the Rock Island Rapids. These were finger-like rock projections that protruded from the banks. These rapids made it very difficult for steamboats to travel through. A small industry grew to help these boats navigate the water. Boat crews needed rest areas before they reached the dangerous rapids. They also needed to hire expert pilots to guide them through the rocks. One famous pilot was Phillip Suiter, the first licensed pilot on the upper Mississippi.

When water levels were low, goods were moved by wagon around the rapids. Today, the rocks are submerged six feet underwater by a lake. This lake was created by the use of two locks and dams.

The Industrial Revolution brought even more development to the region. Entrepreneurs looked to the Mississippi River for power generation. The combination of energy and easy transport attracted many industrialists. In 1848, John Deere moved his plough business to Moline. His company was incorporated in 1868. Today, John Deere is the largest employer in the Quad Cities.

Transportation also changed with the arrival of the railroad. In 1856, the Rock Island Railroad Company built the first bridge across the Mississippi. This bridge connected Davenport and Rock Island. It replaced slow seasonal ferries and winter ice bridges. This new technology even led to a famous legal case. After a steamboat crashed into the bridge, Abraham Lincoln served as the trial lawyer. He won the case after taking it to the US Supreme Court.

The identity of the region has evolved through several different names. After the Civil War, the river towns began to develop a common identity. By World War I, Davenport, Rock Island, and Moline called themselves the "Tri-Cities." They grew around a small bend in the Mississippi River. During the 1930s, the term "Quad Cities" became popular as East Moline gained equal status.

The name changed again when Bettendorf grew very quickly. An Alcoa plant opened east of Davenport in 1948. This growth led some to suggest the name "Quint Cities." However, the name "Quad Cities" was already too famous to change. Local officials chose to keep the name to remain inclusive of all five cities.

Economic changes in the late 1970s caused significant industrial restructuring. Many large agricultural manufacturing companies scaled back their operations. Factories like International Harvester in Rock Island and Case IH in Bettendorf closed. Moline-based John Deere also cut its labor headcount by half. Later, Caterpillar closed factories in Mount Joy and Bettendorf. Since the 1990s, the region has worked hard to revitalize its economy.

New projects include the River Renaissance in Davenport. Moline has also invested in its downtown area. They opened the John Deere Commons and the Vibrant Arena at The MARK. These efforts helped the area regain its strength.

The Quad Cities have received many honors for their recent growth. In 2007, Davenport and Rock Island were named the "most livable small city." In 2008, CNN ranked Bettendorf as a top place to buy a house. The area was also named the "most affordable metro" by Forbes in 2010. By 2012, the region was recognized for fast growth in high-tech jobs.

Modern Woodman Park was even voted the best minor league ballpark in America in 2013. These successes show how the region continues to adapt and grow.
