The Quad Cities is a group of cities. 

The Quad Cities is a group of five cities. 
Long ago, many people lived near the river. They used the water to live and trade. 
Boats used to travel on the river. The water had rocky spots. This made it hard for boats to pass.
People built a bridge to cross the water. This helped people move much faster.
Many people work in big factories here. One famous company is John Deere.

Long ago, Native American tribes lived by the river. They used the water to trade. Later, steamboats traveled the river. The water had rocky spots called rapids. These rocks made travel hard. Now, the rocks are under a lake. 
Many people work in big factories. One famous company is John Deere. It started in Moline in 1848. It is the largest employer in the area today. 
The Quad Cities is a special region made of five cities. 


Long ago, many different cultures lived near these rivers. Indigenous peoples used the riverbanks for their homes for thousands of years. The Sauk and Fox tribes used the water for trading. The Sauk people had a large village called Saukenuk. Later, steamboats became a major way to travel. The river had rocky spots called the Rock Island Rapids. These rapids were hard for boats to cross. Pilots like Phillip Suiter helped guide boats through the rocks. Today, those rocks are six feet under a lake. 
Industry helped the cities grow very quickly. Many people wanted to use the river for power. In 1848, John Deere moved his plough business to Moline. 
The region has changed its name many times. In the early 1900s, people called the area the "Tri-Cities." This name described Davenport, Rock Island, and Moline. By the 1930s, people started using the name "Quad Cities." This was because East Moline became an important part of the group. 
Life in the Quad Cities has seen many changes. In the late 1970s, many large factories closed down. Companies like International Harvester and Caterpillar had to change how they worked. Since the 1990s, people have worked hard to make the area new again. 

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. 
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. 
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. 
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. 
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. 
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. 
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.
